The invention discloses a Kinect calibration method and a device based on a plane mirror, wherein the method comprises: installing the Kinect camera, and fixing the relative position with the displayand placing a mirror surface at a preset position so that the Kinect camera acquires images of the display through the mirror surface, replaces the mirror surface with a preset replacement, and shootswith the Kinect camera to determine three-dimensional point cloud data of the mirror surface plane according to the depth information of the depth image; replacing a preset substitute by a mirror surface, and taking the images of the display by a Kinect camera through the mirror surface, dividing the pixel positions of the display and the corner points of the display by a color image, and determining the three-dimensional point cloud of the display and the virtual image space positions of the display angles in the mirror surface by combining the depth images, obtaining the spatial position ofthe current display plane and the corner point by the mirror position and the virtual image plane of the display and the corner point position in the mirror. The method does not need the aid of otherequipments, and the algorithm is simple and easy to implement.
Description
technical field [0001] The invention relates to the technical field of camera calibration, in particular to a plane mirror-based Kinect calibration method and device. Background technique [0002] The Kinect camera is an XBOX360 somatosensory peripheral peripheral officially announced by Microsoft at the end of 2010. It uses functions such as real-time dynamic tracking, image recognition, microphone input, and voice recognition to allow players to get rid of the shackles of traditional gamepads and control games through their own body movements. The Kinect consists of a color camera, an infrared projector, and an infrared camera. The color camera acquires a color image of the scene, the infrared projector actively projects the near-infrared spectrum, and the infrared camera analyzes the infrared spectrum to create a depth image within the scene. In 2014, Microsoft released the second-generation Kinect V2, which greatly improved the hardware, and the depth ranging was changed...
