Exemplary embodiments provide an image vision processing method, device and equipment and relate to: determining parallax and depth information of event pixel points in a dual-camera frame image acquired by Dynamic Vision Sensors; determining multiple neighboring event pixel points of each non-event pixel point in the dual-camera frame image; determining, according to location information of each neighboring event pixel point of each non-event pixel point, depth information of the non-event pixel point; and performing processing according to the depth information of each pixel point in the dual-camera frame image. Since non-event pixel points are not required to participate in the matching of pixel points, even if it is difficult to distinguish between the non-event pixel points or the non-event pixel points are occluded, depth information of the non-event pixel points can be accurately determined according to the location information of neighboring event pixel points.

PURPOSE: A feature point setting apparatus, an object tracking apparatus using the same and an object tracking method using the same are provided to calculate a variability representative value regarding a block by considering a surrounding pixel matrix of a feature point which is manually designated by a user. CONSTITUTION: A feature point defining unit(110) stores a feature point by receiving the feature point designated by a user about an input image.

The present invention relates to an apparatus and method for setting feature points, and to an apparatus and method for object tracking using same. According to the present invention, when a user designates feature points, a representative value of variability for each block is obtained in consideration of the pixel matrix surrounding the user-designated feature points, and the user-designated feature points are reset on the basis of the representative value of the variability. Accordingly, in terms of a stereoscopic conversion, the accuracy of feature point tracking for the outer contour of the object may be increased. In addition, a key frame whose total sum of errors is at the minimum can be easily found and selected through only simple calculation without having to track each frame.
