| description | The invention discloses a laser scanner system error calibration target selection method and system and a storage medium, and the method comprises the steps: taking the coordinates of a target center in a scanner coordinate system and a total station coordinate system as a homonymy point pair in a process of calibrating a three-dimensional scanner system error through a high-precision total station, building an error equation according to a system error self-calibration model, and carrying out the calibration of a three-dimensional scanner system error. Calculating a geometric contribution factor and a precision contribution factor of each target, obtaining precision evaluation factors of all the targets, sorting the precision evaluation factors according to the size, if the minimum evaluation factor is less than 0, removing the target corresponding to the minimum precision evaluation factor, reestablishing an error equation by using the residual targets, and repeating the process until the error coefficient |
