Abstract
The present technology is directed to validating a lidar system based on an asymmetric illumination pattern. More specifically, the present technology is generally related to determining a positioning error between a laser-based light source and a lens in a lidar system based on the asymmetric illumination pattern. The present technology can project the light source through the lens adjacent to the light source, receive an illumination pattern representing a distribution of light intensity across the field of view, compare the illumination pattern with a set of illumination patterns to determine a matching illumination pattern that is substantially corresponding to the illumination pattern, and determine whether the matching illumination pattern is within a predetermined range of the set of illumination patterns.
