Abstract
A sensor alignment method including detecting, detecting an object within a first sensor field of view and a second sensor field of view, detecting a plurality of depth point clouds of the first field of view in response to the object being stationary, the host vehicle being stationary, and the distance between the object and the host vehicle being less than a threshold distance, aggregating the plurality of depth point clouds into an aggregated depth point cloud, detecting a first location of an edge of the object in response to the aggregated depth point cloud, detecting a second location of the edge of the object using an edge detection algorithm on the image, generating a lidar to camera alignment in response to a difference between the first location and the second location.
