Abstract

The invention relates to the technical field of image processing, and provides a trajectory tracking method and device, and the method comprises the steps: obtaining a first image which is collected by a camera and comprises a calibration board, and obtaining a first relative relation between the camera and the calibration board according to the first image; obtaining a second relative relation between the first position acquisition unit and the second position acquisition unit; according to the first relative relationship, the second relative relationship and a preset third relative relationship, a fourth relative relationship between the camera and the first position acquisition unit is obtained, and the third relative relationship represents the relative position relationship between the calibration plate and the second position acquisition unit; and carrying out track tracking on the camera according to the first position information of the first position acquisition unit and the fourth relative relation. Compared with the prior art, the trajectory tracking method and device provided by the invention can improve the precision of tracking the trajectory of the camera.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a trajectory tracking method and device. Background technique [0002] Vision-based localization and mapping (Simultaneous Localization And Mapping, SLAM), hereinafter referred to as visual SLAM. Visual SLAM is currently playing a very important role in augmented reality (Augmented Reality, AR), automatic driving, 3D reconstruction, and robotics industries, mainly for positioning and navigation. [0003] Visual SLAM needs to obtain the real-time position information of the camera, that is, track the camera’s trajectory. In the prior art, the accuracy of the camera’s trajectory tracking is not high, resulting in the low accuracy of visual SLAM. Contents of the invention [0004] The purpose of the present invention is to provide a trajectory tracking method and device to improve the problem in the prior art that the accuracy of the trajectory tracking of the ca...
