Method of obstacle detection for a vehicle

The detection procedure involves classifying obstacle (O) detected with indexes of confidence applied to the regions of interest in relation to given characteristics. The classification of the detected object is validated in relation to the indexes of confidence and in relation to the regions of interest to obtain validated regions of interest. The first region of interest is defined by detecting obstacle by shape recognition in acquired image of environment. Second region of interest is defined by detecting obstacle by movement detection in relation to vehicle on sequence of acquired images. Independent claims are also included for the following: (1) an obstacle detection device; and (2) a computer program product.
