Abstract: The present application provides a method for tracking and shooting a moving target and a tracking device, firstly, feature points of a template image corresponding to each shooting angle is extracted in advance, after that, only a feature point of a currently shot target image needs to be calculated when matching, and then the feature points of the target image is matched with the feature points of the template image corresponding to each shooting angle, the shooting angel corresponding to the matched template image is determined as the shooting angle of the currently shot target image; if the shooting angel of the currently shot target image does not coincide with the preset shooting angle of the target, the tracking device is moved to track and shoot the target, so that the shooting angel of the target coincides with the preset shooting angle of the target, greatly reducing the calculation amount of the detection and matching of the feature point and improving the real-time performance of the tracking and shooting.

Abstract: Disclosed are a method and an apparatus for processing feature point matching result, the first image and the second image are placed reversely, and the matching feature point pair between the first image and the second image is determined by using the feature point matching algorithm; the straight-line equation between each of the feature point pair is made mathematically, and the intersection between each straight line and other straight line is determined; the valid intersection group and the geometric center point thereof are determined according to the distance between each of the intersection and other intersection; and the judgment area of the feature point pair is determined according to the geometric center point, and whether the feature point pair is a correct matching result or not is determined according to whether a straight line between the feature point pair passes through the judgment area or not.
