A number of different methods and techniques are recognized in the art for making depth maps. The words “depth map” (and “3Dmap” in the patent application ) can be used interchangeably to mean a representation of a scene in two-dimensional pixels. Each pixel is associated with a specific location in the scene, and each pixel has a respective value which indicates the distance between the reference location and the actual location. The depth map is a type of image in which the values of the pixels indicate topographical information rather than the hue or brightness of objects in the scene.
Depth maps can be made, for example, by the detection and processing of images of an object over which the pattern is projected, like a laser speckle pattern as described in the PCT International Publication WO 2007/043036 A1, whose disclosure is included herein by reference. U.S. Patent Application Publication 08/0240502 provides a method for mapping objects by using an illumination assembly. It comprises an opaque that contains the pattern fixed with spots that projects the pattern onto an object. An image capture assembly captures images of the pattern that is projected onto an object. The image captured by the image capassembly is processed by a computer to create a 3D model of the object.
In reality, depth mapping systems (as with other imaging systems) are constrained by light intensity and optical resolution. The embodiments of the invention are described below and provide techniques that could be used to optimize these resources in order to enhance overall system performance.
In accordance with an embodiment of the invention there is a method of depth mapping. This involves providing resources for depth mapping that include an illumination module which project patternedoptical radiation into the volume of interest that contains the object and an image capture module that records patterns reflected by the object. The resources are utilized to create a depth map of the object. At the very least, one resource is applied non-uniformly across the volume of importance.
Some embodiments have the volume of interest having an incline that alters with angle relative to the image capture and illumination modules. This means that the most likely resource will be applied differently that is, it can change the application of at least one of the resources according to the angle’s different depth. In one embodiment disclosed the area of interest is the shape of a pentagonal, and has a vertex at the image capture module. Varying the application of the at the very least one of them in a non-uniform manner could involve angularly altering the intensity distribution of the patterns of the optical radiation produced by the illumination module. Additionally or alternatively, varying the application of the at least one of the resourcesnon-uniformly may include optically distorting the image captured by the image capture module.
The illumination module in the described embodiments is constructed to project a spatial pattern from the optical radiation on an object. In order to generate the depth map, it involves determining the depth coordinates of the object using shifting of the transverse in the spatial pattern.
In accordance with a different version of the invention there is a device to map depth. The apparatus comprises depth mapping resources, including an illumination module that projects the pattern of the optical radiation into a volume of interest that includes the object as well as an image capture module that detects the pattern that is reflected off of it. At least one of the resources is used non-uniformly over the volume of the object of interest. Aprocessor is used to process the image to create an image of depth.
In accordance with a different embodiment of the invention, there is also an apparatus to map depth. It includes an illumination module designed to project patterned optical radiation with a given patterndistortion into an area of interest containing an item. An image capture module comprises an objective optics and an image sensor. It is configured to produce an image of the pattern that is captured by the image sensor while applying optical distortion to the image to help compensate for at least part of the distortion of the pattern. The image is processed by a processor to create a depth map.
The disclosed embodiment includes an F-theta-lens as the objective optics. A radiation emitter is used to send the DOE to generate the patterned optical radiation.

What is a patent?
A patent is granted by the government to safeguard an invention. The patent grants the inventor the exclusive rights to develop, use and sell the idea. Society gains when new technology is introduced to the market. The benefits can be realized immediately when people can achieve previously impossible feats and indirectly by the opportunities for economic growth that innovation provides (business growth, employment).
Patent protection is demanded out by many university researchers and drug companies for research and development. A patent can cover the physical or abstract nature of a product or process or a method or composition of material unique to the area. Patent protection has to be granted to any invention that is valuable or novel and is not already known by others in the same field.
Patents are a way to give inventors a reward for commercially profitable inventions. They provide a motivation for inventors to come up with new ideas. Patents permit entrepreneurs and inventors to know that there’s a good chance they will receive a return for their efforts, time and investment in technological development. They could earn a decent income by their work.
Businesses that have the capacity to:
Secure the latest products and services;
Enhance the value, visibility, and attractiveness of your products on the market;
Make your company and your products stand out from others;
Find out about business and technical information.
Avoid the risk of accidentally using third-party proprietary content, or losing your important information, creative outputs, or other creative output.
Patents convert knowledge of the inventor into a valuable asset which opens up new opportunities for employment creation by licensing joint ventures and joint ventures.
Small businesses that have patent protection are more appealing to investors who are involved in the commercialization and development of technology.
Patenting could lead to the development of new ideas and inventions. The information you create may be eligible for patent protection.
Patents can serve as an effective deterrent for untrustworthy third parties that profit from the efforts of an invention.
Patent-protected technology that is commercially viable can be used to finance technology-related research and development (R&D), which can increase the chance of better technology in future.
It is possible to use the intellectual property rights of your company to convince investors and lenders that your product is a viable commercial value. One powerful patent may open the door for multiple financing opportunities. Patents can be used along with other IP assets as collateral or security to secure financing. Investors may also look at the patents you own to increase their company valuation. Forbes and other publications have noted that each patent could increase the value of a company by anything from $500,000 to $1 million.
A well-constructed business plan is essential for startups. It must be founded on IP and explain the way your product or service stands out. Investors will be amazed if your IP rights are secure or are in the process of becoming secure, and that they are in line with your business plan.
It is vital to protect an invention prior to filing for patent protection. The public disclosure of an invention prior to filing can often destroy its novelty and make it ineligible for patent protection. Therefore, pre-filing disclosures (e.g. for test-marketing investors, investors, or for other business partners) should only be made upon signing a confidentiality contract.
There are a variety of patents. Knowing them is essential to safeguard your invention. Utility patents are for the development of new methods and machines. Design patents cover ornamental designs. Patents for utility are the most effective because they shield the owner from copycats as well as other competitors. Utility patents are often issued to improve or modify existing inventions. Utility patents can also be used to enhance or modify existing inventions. A process patent will cover the acts or methods of performing a particular act. However, a chemical composition could be a combination of components.
How long does a patent last? Although utility patents are valid for 20 years from the date of the initial filing, they are able to be extended through delay in the Patent Office.
Are you planning to patent your ideas? Patents are granted only to the first-to-file applicants which is why you must file as quickly as possible. Call PatentPC today to file your patent application filed!
When drafting a patent application it is recommended to conduct a patent search, as the search will give you an insight into the other applicants’ ideas. This allows you to limit the scope of your invention. Also, you can learn about the latest developments in your area of invention. This will assist you in understand the scope of your invention and help prepare you for filing your patent application.
How to Search for Patents
Patent searches are the initial step in obtaining your patent. You can do a google patent search or do a USPTO search. Once the patent application is submitted, the product that is covered by the application can be described as patent-pending. you can find the patent application on public pair. After the patent office has approved the patent application, you are able to conduct a patent number search to find the patent that was issued and your product will now be patented. Alongside the USPTO search engine, you can use other search engines like espacenet, as detailed below. You can get help from an attorney who specializes in patents. In the US Patents are granted by the US trademark and patent office or by the United States patent and trademark office, which also examines trademark applications.
Are you interested in finding similar patents? Here are the steps you should follow:
1. Think of terms that describe your invention in relation to its intended and composition or use.
Write down a short and precise explanation of your invention. Do not use generic terms such as “device”, “process,” or “system”. Instead, think about synonyms for the terms you chose initially. Then, take note of important technical terms and keywords.
To help you find terms and keywords, you can use the questions below.
- What is the goal of the invention Is it a utilitarian device or an ornamental design?
- Is the invention a method of creating something , or performing an action? Is it an object?
- What is the basis of the invention? What is the physical makeup of the invention?
- What’s the point of this invention?
- What are the terms in the technical field and keywords that define the nature of an invention? To help you find the appropriate terms, use the technical dictionary.
2. These terms will enable you to find pertinent Cooperative Patent Classifications using the Classification Search Tool. If you are unable to locate the appropriate classification to describe your invention, scan through the Schemas of classes (class schedules). If you don’t see any results from the Classification Text Search, you may want to consider replacing the words to describe your invention using synonyms.
3. Go through the CPC Classification Definition to determine the accuracy of the CPC classification you’ve found. The hyperlink to a CPC classification definition is given when the classification you have selected has a blue box that includes “D” on the left. CPC classification definitions can help you determine the applicable classification’s limits so that you can choose the one that is most appropriate. In addition, these definitions can include search tips and other suggestions that could be useful for further research.
4. Get patent documents using the CPC classification from the Patents Full-Text and Image Database. By focusing on the abstracts and representative drawings it is possible to narrow your search for the relevant patent documents.
5. This list of patent publications is the most appropriate to examine for connections to your idea. Take note of the specifications and claims. Consult the applicant and patent examiner to obtain additional patents.
6. Find patent applications published in the public domain using the CPC classification you picked in Step 3 from the Applications Full-Text and Image Database. You can use the same strategy of searching as in Step 4. You can narrow your results to the most pertinent patent application through the abstract as well as the illustrations on every page. Then, you must carefully review the published patent applications and pay particular attention to the claims as well as additional drawings.
7. You can search for additional US patent publications using keywords searching in AppFT or PatFT databases, as well as classification searching of patents not from the United States in the following table. You can also make use of search engines on the internet to search for non-patent-related patent disclosures in literature about inventions. Examples:
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
