PROBLEM TO BE SOLVED: To provide a method, apparatus and system for measuring an obstacle, capable of improving accuracy of distance information, reducing its circuit scale and shortening its processing time. SOLUTION: In the method for measuring the obstacle, a distance from the obstacle is measured by calculating a parallax error in a stereo image, the reliability of a value of the parallax error calculated from a low-resolution image is obtained, and then a window size for searching corresponding points is set based on the reliability, in order to calculate a parallax error of a high-resolution image.
