titleOfInvention Instrument and equipment pose measurement and error compensation method based on mark-free anchor point detection
abstract The invention provides an instrument and equipment pose measurement and error compensation method based on label-free anchor point detection, which comprises the steps of detecting anchor points of instrument and equipment on an image by using a trained deep neural network model of DeepLabCut, and outputting an X coordinate, a Y coordinate and a confidence coefficient of each anchor point in the image; in the initialization stage, a calibration plate is used for calibrating camera parameters and the physical distance of anchor points of a measuring instrument, and all anchor points, world coordinates of the anchor points and the distances among the anchor points form an anchor point network topology; and detecting an anchor point set on the new image, calculating a rotation matrix and an offset vector at the moment according to the anchor point network topology, the world coordinates and the camera internal parameters, and calculating the camera coordinates of the anchor points. The overall pose of the instrument is a rotation matrix, an offset vector, where the camera coordinates of each anchor point are the position of each anchor point in space.
