Measured distance correction method for anticollision

摘要

The correction method involves using measured distance values provided from an image obtained via an imaging module with a pair of image sensor devices (20). Each has a number of image sensors (21,22) and an associated optical device (11,12). The field of view of the imaging module is divided into a number of windows, arranged in a two-dimensional matrix. The distance values are determined for each window using a parallax principle. Subsequent correction of the distance values is performed using a defined polynomial with vertical and horizontal values defining the position of the window within the two-dimensional matrix.
