Solution Overview
Problem
Conventional stereo vehicle exterior monitoring systems using multiple infrared cameras are costly and inefficient, as they require multiple cameras to calculate distance data for monitoring surroundings.
Innovation Solution
A computer-readable image processing program that determines the position of a subject in an infrared image based on brightness and size of a prescribed region, allowing for accurate position determination using a single image pick-up portion, which can obtain both infrared and non-infrared images, and incorporates an infrared ray projection function to enhance accuracy.
