This disclosure is of a general nature and is related to decompression or compression point clouds that contain a plurality points each with associated attributes.
Description of Related Art
There are many types of sensors, including light detection and range (LIDAR), 3-D-cameras, scanners and 3-D-cameras. may capture data indicating positions of points in three-dimensional space, for example locations in the X three, Y and Z planes. These systems can also capture attributes data, such as spatial information for each point, such as color information (e.g. RGB values), intensity attributes, reflectivity attributes, motion-related attributes, modalityattributes, and various other attributes. Additional attributes can be assigned to points under certain situations, for example, the date at which the point was made. These sensors can capture points and then create an “point cloud” that could comprise a collection of points with related spatial information as well as other attributes associated with them. In certain situations points clouds can include thousands of points, hundreds of thousands of points, millions of points, or more points. In some cases point clouds may be developed in software, rather than being captured by one or two sensors. Point clouds can contain large quantities of information, which can be expensive and time-consuming to store or transmit.Click here to view the patent on USPTO website.

What is a patent?
How to Search for Patents
- 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.
