Hand key point calibration method and device

The embodiment of the invention discloses a hand key point calibration method and device. The method comprises the steps: acquiring infrared images collected by a plurality of image collection devices for a gesture display area; based on a pre-established key point detection model, determining detection position information and detection semantic information of hand key points in the target gesture from each infrared image; grouping the infrared images to obtain at least one infrared image group; determining target spatial position information corresponding to target detection semantic information by utilizing detection position information of a hand key point corresponding to the detection semantic information corresponding to each infrared image group and equipment information corresponding to the detection position information; and on the basis of target spatial position information corresponding to the target detection semantic information and equipment pose information and equipment internal reference in
