Abstract

The embodiment of the invention provides an image processing method and device, and AR equipment; the method comprises the following steps: determining continuous a first frame image and a second frame image in a continuous video frame image sequence, wherein the second frame image is the present frame image, and the first frame image is the image in front of the second frame image; using a targetarea of the first frame image as a template to determine the position information of the target area in the second frame image; using the position information as an iteration initial value so as to carry out iteration processing for the first and second frame images in whole graph alignment, wherein the iteration processing for the first and second frame images in whole graph alignment uses a robustness error function for iteration. The image processing method and device, and the AR equipment can improve the tracking success rate of the whole system.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer vision effects, and in particular, to an image processing method, device, and AR device. Background technique [0002] Object tracking is one of the hotspots in the field of computer vision research and has been widely used. Such as video surveillance, traffic flow monitoring, unmanned driving, face recognition, augmented reality technology (Augmented Reality, AR) and so on. For example, the tracking focus of the camera, the automatic target tracking of the drone, etc. all need to use the target tracking technology. In addition, the tracking of specific objects, such as human body tracking, vehicle tracking in traffic monitoring systems, face tracking and gesture tracking in intelligent interactive systems, etc., all require the use of target tracking technology. [0003] Target tracking is to establish the positional relationship of the object to be tracked in a continuous video se...
