Problems solved by technology

Practice has found that the above-mentioned existing relocation methods require that the reference frame image must have a sufficient number of three-dimensional space points, otherwise the matching cannot be successfully achieved or an accurate matching relationship cannot be obtained, resulting in relocation failure or large errors in relocation results

Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0040] An embodiment of the present invention provides an image-based relocation solution, which can be applied to a terminal to realize relocation of the terminal. The terminals here may include, but are not limited to: virtual display head-mounted display devices such as VR glasses and VR helmets, and mobile platforms such as mobile robots, driverless cars, and drones. The following will take the terminal as a VR helmet as an example, combining Figure 1a-Figure 1b The implementation process of the image-based relocation solution in the embodiment of the present invention will be described. It can be understood that when the terminal is other equipment than the VR helmet, the analysis can be performed with reference to the example of the VR helmet.

Abstract

The embodiment of the invention discloses an image-based relocation method and device, a terminal and a medium, wherein the method comprises the following steps: obtaining a current frame image and areference frame image from an image set; Extracting first feature information from the current frame image and extracting second feature information from the reference frame image, and obtaining a matching relationship between the first feature information and the second feature information; Determining a position parameter of the current frame image according to the matching relationship, the position parameter comprising a rotation parameter and a displacement parameter; Adjusting a position parameter of the current frame image according to a three-dimensional spatial position correspondingto the reference frame image and the matching relationship; determining The three-dimensional spatial position of the terminal according to the adjusted position parameters. The embodiment of the invention can improve the success rate of repositioning and the accuracy of the repositioning result.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to the technical field of image processing, and in particular to an image-based relocation method, an image-based relocation device, a terminal and a computer storage medium. Background technique [0002] In the process of using a terminal such as VR (Virtual Reality, virtual reality) glasses, a VR helmet, etc., it is usually necessary to track and locate the position of the terminal based on images collected by the terminal. Image-based positioning will inevitably lead to positioning failure due to various situations, for example: the camera of the terminal is blocked, or the captured image is blurred due to excessive motion of the terminal, or the ambient light is too bright or too weak , then the terminal needs to be relocated. The existing image-based relocation technology refers to obtaining the current frame image collected by the terminal's camera when the termi...
