Method for detecting obstacle in car surroundings, involves detecting image by monocular image capture system, comparing intensity difference with predetermined threshold, and detecting obstacle when difference is larger than threshold

摘要

The method involves detecting an image by a monocular image capture system i.e. monocular camera (2), and detecting feature points of the image in an image area of a track (9) in the image. Difference of an intensity of a transformed pixel of another image and an intensity of a pixel of the former image corresponding to the transformed pixel of the latter image is computed using a calculation unit (5). The difference is compared with a predetermined threshold. An obstacle (10) is detected when the difference is larger than the predetermined threshold. An independent claim is also included for a device for detecting an obstacle in car surroundings.
