Abstract
We examine a gradient method to detect spatial information of the targets surrounding a car using image information of the objects for the anticollision system. More pixels can be calculated and less calculation time can be expected by using a gradient method than by a correlation method or a matching method. In this chapter, we mention the algorithm used to calculate differences between two objects in images with the gradient method in one dimension. In addition, we calculate distance and velocity values of the objects in the images and examine the possibility of using the gradient method in a car application.
