Abstract
An apparatus and method for detecting an obstacle include a camera to photograph first and second images at different points in time successively. A calculator is configured to calculate a movement distance and a rotation amount of a vehicle by comparing the two images photographed by the camera with each other. A rotation amount compensator is configured to compensate for the rotation amount of the first image based on the second image. A difference value calculator is configured to calculate a difference value between the first image of which the rotation amount is compensated for and the second image based on the calculated movement distance of the vehicle. An obstacle detector extracts a region having the difference value exceeding an expectation value to detect the obstacle.
