Abstract

The invention provides a method and a device for verification, applied to the field of image processing, and the method comprises the steps: obtaining a common two-dimensional image, an infrared imageand a depth map of a calibration object, and enabling the calibration object to be provided with a first mark; calculating the imaging coordinates of the first mark on the infrared image; and obtaining the depth value of the first mark according to the depth map, calculating the projection position of the three-dimensional point cloud corresponding to the imaging of the first mark on the infraredimage on the common two-dimensional image, and calculating the distance between the imaging of the first mark on the common two-dimensional image and the projection. According to the method and the device for verification provided by the invention, the calibration parameters obtained when the depth camera device is calibrated can be verified, and the calibration accuracy is improved.

Description

technical field [0001] The present invention relates to a method and device for image processing, in particular, to a method and device for verification. Background technique [0002] At present, with the rapid development of robotics, artificial intelligence and other industries, it is no longer satisfied with two-dimensional image information, and the demand for depth vision is becoming more and more prominent. The depth camera can obtain the three-dimensional size and depth information of the surrounding environment objects in real time, and more realistically restore the world seen by the human eye, thus bringing users a more natural and realistic experience. At present, depth cameras are commonly used in real-time positioning and map construction SLAM (Simultaneous Localization and Mapping), immersive interaction, unmanned driving, 3D reconstruction, gesture recognition, 3D face recognition and other fields. [0003] In the prior art, there is a lack of methods and dev...
