    Abstract: 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.

    Abstract: A control method includes: estimating, in a first image within an image series, a plurality of sets including candidate regions and indexes according to image feature quantities of the first image, the candidate regions being regions in which presence of an object is estimated within the first image, the indexes being values indicating possibilities of the presence of the object in the candidate regions; obtaining movement information about movement of the object from the image series; correcting the candidate regions and the indexes in the plurality of sets based on the movement information obtained by the second processing; and determining the position of the object in the first image based on the plurality of sets including the corrected candidate regions and the corrected indexes.
