Abstract
Disclosed is a method for image processing that can compensate for inconsistent edge detection wherein: the field of view of a stereo camera is segmented in the form of a matrix by angle and by measured range value based on parallax; matrix data is calculated for a segment where a detected edge exists, and also for segments surrounding the segment, the calculated matrix data then being assigned to each of the segments; a search is made through the assigned matrix data to find a segment that has matrix data exceeding a predetermined threshold value; and if the detected edge exists in the thus found segment, edge data of the edge is taken to represent the position of an object.

A method for image processing, wherein
- the field of view of a stereo camera is segmented in the form of a matrix by angle and by measured range value based on parallax,
- matrix data is calculated for a segment where a detected edge exists, and also for segments surrounding said segment, said calculated matrix data then being assigned to each of said segments,
- a search is made through said assigned matrix data to find a segment that has matrix data exceeding a predetermined threshold value, and
- if said detected edge exists in said found segment, edge data of said edge is taken to represent the position of an object.

- a search is made through said assigned matrix data to find a segment that has matrix data exceeding a predetermined threshold value,
- if said edge does not exist in said found segment, said threshold value is successively increased,
- a search is made successively to find a segment that has matrix data exceeding said increased threshold value, and
- if an edge detected at a past point in time corresponding to said increased threshold value exists in said found segment, edge data of said edge is taken to represent the position of an object.
