Problems solved by technology

However, in the process of space-based space detection, due to the influence of atmospheric scattering, refraction, optical defocus, lens deformation, etc., when the ultra-long-distance target object is received by the detector, the signal strength is characterized by dimness and weakness, even invisible to the naked eye. , resulting in an inaccurate determination of the location of the target object

Abstract

The invention provides a method and device for determining the position of a target object, computer equipment and a medium. The method comprises the following steps: acquiring continuous multi-frame images containing a target image; performing signal enhancement on a first pixel point in the target image; determining a first motion area of the target object in the continuous multi-frame image by using the position of the target object in the continuous multi-frame image; and determining the position of a second pixel point in the target image as the position of the target object in the target image. By calculating the enhancement factor of each pixel point, the local contrast of the target object is enhanced in the target image, and the accuracy of determining the position of the target object is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to a method, device, computer equipment and medium for determining the position of a target object. Background technique [0002] With the development of science and technology, human beings explore space more and more frequently, and the detection of space targets is of great significance to perceive the space situation and maintain the safety of the space environment. [0003] Space target detection is mainly divided into two types: ground-based and space-based. Compared with traditional ground-based space target detection, space-based space target detection has wide detection coverage and strong detection capabilities, and has become a key development direction of various countries in recent years. However, in the process of space-based space detection, due to the influence of atmospheric scattering, refraction, optical defocus, lens deformation, etc., when th...
