RADAR MAP LAYER IN A CROWDSOURCED HD MAP - A simplified explanation of the abstract

• This abstract for appeared for patent application number 17658619 Titled 'RADAR MAP LAYER IN A CROWDSOURCED HD MAP'

Simplified Explanation

The abstract describes a method for creating and updating a detailed radar map layer for high-definition (HD) maps using crowdsourcing. This involves a vehicle collecting radar data and filtering it on a frame-by-frame basis. Additional filtering may also be done on a batch of frames. Once the radar data is filtered, the vehicle can transmit it to a central system. This transmission is triggered when the vehicle's position estimate reaches a certain confidence level or when the reliance on radar data for the position estimate exceeds a certain threshold.

Original Abstract Submitted

Creating and updating an accurate radar map layer for HD map using crowdsourcing may comprise a vehicle obtaining radar data and filtering the radar data on a frame-by-frame basis. In some embodiments, additional filtering may be made on a batch of frames. The vehicle can then transmit the filtered radar data responsive to a determination that a confidence of a position estimate of the vehicle exceeds a conference threshold level and/or a determination that a reliance of the position estimate of the vehicle on the radar data exceeds a reliance threshold level.
