Sony patents method to clean radar data using camera images
Sony describes a system that uses a camera to predict what a radar should detect at a specific moment. It then compares this prediction with the actual radar signal to filter out unwanted noise or false readings.
In the filing’s own words
Radar data determination circuitry configured to obtain image data; and determine predictive radar data from the image data based on learned features being represented in the image data for determining actual radar data based on an association of the predictive radar data with radar measurement data.
What exactly they claim (claim 1)
1. Radar data determination circuitry, configured to: obtain optical image data at a particular time; obtain radar measurement data having a time stamp corresponding to the particular time; determine predictive radar data from the optical image data obtained at the particular time based on learned features correlating optical characteristics represented in the optical image data obtained at the particular time to radar characteristics; associate the predictive radar data determined from the optical image data obtained at the particular time with the radar measurement data having the time stamp corresponding to the particular time; and determine actual radar data by removing radar information from the radar measurement data having the time stamp corresponding to the particular time based on the association of the predictive radar data determined from the optical image data obtained at the particular time with the radar measurement data having the time stamp corresponding to the particular time.
