Problems solved by technology

[0003] At present, the trajectory of the moving target is usually determined by GPS technology. However, due to obstacles such as tunnels and weak GPS signals, the trajectory data of the moving target cannot be accurately obtained. Therefore, it is necessary to use the measuring equipment of the moving target to obtain the trajectory in the tunnel. However, the measurement system usually also has errors, and the resulting trajectory is of low accuracy

Embodiment Construction

[0031]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] figure 1 It is an application environment diagram of the trajectory data processing method provided in one embodiment, such as figure 1 As shown, in this application environment, a target object 110 and a computer device 120 are included.

[0033] When the target object moves in a place such as a tunnel where the track obtained by positioning is inaccurate, in order to obtain accurate track data, the computer device 120 can obtain the track start data and track end data corresponding to the target object, where the track start The data and track termination data are data obtained by positio...

Abstract

The invention relates to a track data processing method and device, computer equipment and a storage medium. The method comprises the steps that track starting data and track ending data correspondingto a target object are acquired, wherein the track starting data and the track ending data are obtained according to positioning, or the track starting data and the track ending data are closed-looptrack data; a corresponding initial correction track data sequence is acquired according to the track starting data and the track ending data, wherein the initial correction track data sequence comprises multiple pieces of initial correction track data, and the initial correction track data is obtained by performing filtering according to measured motion data and predicted motion data corresponding to the target object; and each piece of initial correction track data in the initial correction track data sequence is adjusted according to the track starting data and the track ending data to obtain a target correction track data sequence, wherein the target correction track data sequence is used for determining a target track corresponding to the target object. Through the method, the accuracy of the track data of the target object can be improved.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a trajectory data processing method, device, computer equipment and storage medium. Background technique [0002] With the development of information technology, people pay more and more attention to pattern recognition and fault monitoring of moving objects such as automobiles or aircrafts. The trajectory of the target object is a prerequisite for map generation, pattern recognition, and fault detection. [0003] At present, the trajectory of the moving target is usually determined by GPS technology. However, due to obstacles such as tunnels and weak GPS signals, the trajectory data of the moving target cannot be accurately obtained. Therefore, it is necessary to use the measuring equipment of the moving target to obtain the trajectory in the tunnel. However, there are usually errors in the measurement system, and the resulting trajectory has low accuracy. Contents of the invention...
