METHOD (OPTIONS) AND SYSTEM FOR CALIBRATING SEVERAL LIDAR SENSORS Russian patent published in 2022 - IPC G01C21/00 G02B26/10 

FIELD: car industry.

SUBSTANCE: present technology relates to computer-implemented methods and systems for calibrating several lidar sensors installed on a self-driving car (hereinafter – SDC) using iterative closest point algorithm (ICP). The method contains stages, at which: (i) at least some of a set of the first data points and (ii) at least some of a set of the second data points are selected by means of an electronic device; the first data points are coordinated with the second data points by means of the electronic device, thereby determining a set of pairs; an error value specific for the pair is determined by means of the electronic device for a given one of the set of pairs; a weight factor is determined by means of the electronic device for a given one of the set of pairs based on a normal vector associated with this second data point in a given one of the set of pairs; and a global error value is determined by means of the electronic device for the second dataset.

EFFECT: increase in the accuracy of detecting objects in the surrounding SDC area.
