14. A range-finding method in a multi-lens camera system that has multiple camera units including respective optical filters and image sensors that acquire captured image via the optical filters, each of the optical filter having multiple filter regions whose optical characteristics differ respectively;
-
the method comprising the steps of; capturing images; dividing each of the captured images into multiple image regions corresponding to the respective filter regions; calculating parallax information for a first image region in the captured image where a first target object is recognized; performing clustering using the parallax information for the first image region; recognizing a second target object for a second image region in the captured image while calculating parallax information and performing clustering using the parallax information for the first image region; modifying the clustering result; calculating parallax information only for the area where the second target object is recognized in the second image region, while modifying the clustering result for the first image region; and recognizing the targets in the first image region and the second image region in the captured image in three dimensions. - View Dependent Claims (15)
