The present invention discloses a distance measurement method and apparatus, and an unmanned aerial vehicle using same. According to the distance measurement method and apparatus, and the unmanned aerial vehicle provided in embodiments of the present invention, foreground and background segmentation is performed on two neighboring frames of images, and edge feature extraction is performed by using enlarged regions of interest (ROIs) to obtain measurement changes of the images. By means of the measurement changes of the images, remote-distance obstacle avoidance in an extreme condition can be implemented, and problems such as poor stereo matching precision or unavailability of stereo matching in extreme cases such as no texture, low textures, and dense and repeated textures are resolved.
