Embodiment Construction

[0072] 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.

[0073] The image processing method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 50 and the server 60 communicate through the network. The terminal 50 obtains the image corresponding to the preset calibration target, and transmits the image corresponding to the preset calibration target to the server 60 through the network. The server 60 identifies the logo in the image to obtain the large logo and the small logo in the logo; further according to the large logo, establish the topological coordi...

Abstract

The invention relates to an image processing method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring an image corresponding to a preset calibration target, and identifying an identifier in the image to obtain a large identifier and a small identifier in the identifier; further establishing a topological coordinate system of the image according to the large identifier; and determining an image coordinate corresponding to the preset calibration target according to the topological coordinate system, the large identifier and the small identifier. Accurate external parameter calibration between the three-dimensional laser radar and the monocular camera can be carried out on the specific calibration target.

Description

technical field [0001] The present application relates to the technical field of external parameter calibration, and in particular to an image processing method, device, computer equipment and storage medium. Background technique [0002] Calibration is a basic problem in the field of computer vision and robotics. It mainly refers to the use of standard measuring instruments to test whether the accuracy (precision) of the instruments used meets the standards. Generally, it is mostly used for instruments with high precision. Calibration can also be considered is the calibration. [0003] In a mobile platform equipped with two types of sensors, such as a self-driving vehicle and a laser radar and a monocular camera, calibration between the laser radar and the monocular camera is required. According to the characteristics of the two types of sensors to be calibrated, laser radar and monocular camera, it is necessary to design a corresponding calibration device to achieve the p...
