Abstract
A method for walk error correction in a lidar system. A preliminary peak location of a received laser pulsed is compared to a threshold. If the preliminary peak location is within the threshold, walk error correction is applied. A pulse starting point is obtained by locating a predetermined number of consecutive increasing intensity values. A corrected peak location is obtained using the pulse staring point, and it is used for time of flight calculation. There are other embodiments as well.
