Abstract

An apparatus comprising an interface and a processor. The interface may receive pixel data and radar data. The processor may process the pixel data arranged as video frames, calculate an intrinsic matrix for an image sensor, generate image mapping points to an environment, generate an image transformation matrix in response to the mapping points, the intrinsic matrix and depth data, define a valid area in response to the radar data of an object, generate radar mapping points in response to an environment, generate a mapping function in response to the radar mapping points and a transfer operation, and implement a coordinate transformation in response to the image transformation matrix and the mapping function. The coordinate transformation may be configured to transfer radar coordinates to image coordinates in response to the mapping function and transfer the image coordinates to environment coordinates using the image transformation matrix.
