Abstract

The invention discloses a target detection method and device, and a computer storage medium. The target detection method comprises the steps of obtaining a template image; determining a target candidate region from the current frame image to be detected; calculating a first similarity between the target candidate region and the template image based on the perceptual hash feature; calculating a second similarity between the target candidate region and the template image based on the FHOG features; and making a common decision based on the first similarity and the second similarity so as to determine a current target area corresponding to the template image from the target candidate areas of the current frame image. In this way, the current target area can be accurately determined.

Description

technical field [0001] The invention relates to the field of image target detection, in particular to a target detection method, device and computer storage medium. Background technique [0002] UAV (Unmanned Aerial Vehicle, UAV) autonomous flight control technology is a research hotspot in the field of UAV. Landing technology is an important component of UAV flight control technology. Visual positioning can analyze the image sequence returned by the UAV very well, calculate the two-dimensional coordinate position of the ground target on each frame of image, and then convert the image coordinate system into the world coordinate system, and then the ground target’s position can be obtained. actual location. [0003] In the prior art, the perceptual hash algorithm is generally used to compare the ground target with the template image to determine whether the ground target is the location where the UAV needs to land. But since perceptual hashing algorithm is not geometric ro...
