Equipment calibration method, device and system and storage medium

The invention discloses an equipment calibration method, device and system and a storage medium. The equipment calibration method comprises the steps that a target space range is determined from candidate space ranges according to the type of equipment to be calibrated, at least one calibration plate is deployed in the candidate space range, and the equipment to be calibrated comprises first equipment and second equipment; in the target space range, calibration data are obtained through the to-be-calibrated device, and the calibration data comprise image data collected by the first device for the calibration board and optimization data collected by the second device; detecting image data in the calibration data, and determining position information of the marked feature points; and performing synchronous parameter optimization in combination with the position information and the optimization data to obtain calibration parameters of the to-be-calibrated equipment. According to the invention, the technical prob
