Embodiment Construction

[0071] In order to make the purpose, technical solution and advantages of the present application clearer, the present application 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 application, and are not intended to limit the present application.

[0072] The positioning method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the image acquisition device 102 and the odometer 104 set on the mobile device 10 communicate with the processor 106 through a network. The processor 106 acquires the image to be detected through the image acquisition device 102, and performs road sign image detection on the image to be detected, and when a straight line image is detected on the image to be detected, performs color screening on the straight lines in the straight line...

Abstract

The invention relates to a positioning method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a to-be-detected image, and performing road sign image detection on the to-be-detected image; when a straight line image is detected on the to-be-detected image, performing color screening on straight lines in the straight line image to obtain screened alternative straight lines; mapping the alternative straight line to a preset odometer coordinate system to obtain a straight line parameter of the alternative straight line in the preset odometer coordinate system; detecting and filtering the alternative straight lines according to the straight line parameters to obtain road sign straight lines; determining straight line repositioning information according to the straight line parameters of the road sign straight line; and correcting the pose of the mobile device according to the linear relocation information. By adopting the method, accurate positioning of the mobile equipment can be realized by processing the to-be-detected image, and hardware requirements during positioning of the mobile equipment are reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a positioning method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, mobile devices appear, such as mobile robots, mobile devices, etc., which can be applied in many fields. For example, mobile equipment can be used as an automatic handling tool and play an important role in the logistics transfer yard. [0003] In traditional technologies, when using a mobile device, it is necessary to locate the mobile device. Traditional mobile device positioning methods include laser positioning, electromagnetic guidance positioning, optical guidance positioning, and the like. [0004] However, traditional mobile device positioning methods all have the problem of high hardware requirements. Contents of the invention [0005] Based on this, it is necessary to address the above technical problems and prov...
