Abstract

The invention relates to a target object positioning method and device, an image processing method and device and computer equipment. The method comprises the following steps: acquiring a current image and a reference image; wherein the reference image is an image, including a target object, of one frame before the current image in an image frame sequence where the current image is located; determining a cross-correlation feature between the current image and the reference image; determining a central point position of the target object in the current image according to the cross-correlation characteristics; determining the size of the target object in the current image according to the cross-correlation characteristics; and positioning the target object in the current image based on the central point position and the size. The method can improve the positioning efficiency of the target object.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method for locating a target object, an image processing method, a device and computer equipment. Background technique [0002] With the rapid development of computer technology and image processing technology, more and more fields involve target object positioning in the image during image processing, so as to perform subsequent applications according to the positioned target object. For example, the typical target tracking technology has very important applications in the fields of security monitoring, smart city and driverless driving. [0003] In the traditional target object localization method, a priori frame is usually introduced, and multiple a priori frames are predicted for the target, and then one of the multiple a priori frames is selected as the final positioning result. This will lead to an excessive amount of calculation and affect the efficiency of ...
