Problems solved by technology

[0006] However, this situation requires the user to manually judge the moving direction of the target image and manually adjust the position of the correction area. It is often difficult to quickly and accurately detect and move the screen for a specific target image. Most of the judgments are made by human eyes, the accuracy of judgment is low, and the work efficiency is difficult to guarantee, and it is often difficult to achieve effective tracking of the target

Abstract

The present invention discloses a fisheye image-based target tracking method, a computer device and a computer readable storage medium. The method comprises: acquiring a fisheye image, determining a correction region of the fisheye image, correcting the image in the correction region, and acquiring a corrected image; performing image recognition on the corrected image, and determining a position of a target image; and acquiring the moving direction of the target image, and adjusting the position and / or size of the correction region in the fisheye image according to the moving direction of thetarget image. The present invention also provides a computer device and a computer readable storage medium for implementing the method. According to the technical scheme of the present invention, dynamic tracking of the target image by the user through the monitoring device with the fisheye lens can be facilitated.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method for object tracking based on fisheye images, a computer device for realizing the method, and a computer-readable storage medium. Background technique [0002] With the development of photographing equipment, people widely use various wide-angle lenses to take pictures, among which fisheye lens is a wide-angle lens with an extremely wide viewing angle. Photos taken with fisheye lenses are usually called fisheye images. Due to the large field of view of fisheye images, a single fisheye camera can obtain the content of 180-degree field of view information. This feature makes fisheye lenses more and more popular. It is used in autonomous driving, panoramic monitoring, virtual reality and other fields. However, due to the large distortion of the fisheye image itself, it is necessary to correct the fisheye image through an appropriate mapping relationship and distortio...
