Measurement point coordinate calibration method, device and equipment and storage medium

Abstract

The invention discloses a measuring point coordinate calibration method. The method comprises the following steps: acquiring a real relative distance between a first calibration point and a second calibration point, and acquiring a measured relative distance between the first calibration point and the second calibration point based on at least two measuring points; obtaining a measurement error according to the real relative distance and the measurement relative distance, and circulating the step of obtaining the measurement error by changing the position coordinates of the first calibration point and the second calibration point; and finally, by minimizing the sum of the measurement errors, obtaining the optimized coordinates of the measurement points. The invention further discloses a measuring point coordinate calibration device and equipment and a storage medium. According to the invention, the two calibration points are used for calibrating the measurement points, the measurement errors of the calibration points at different positions are synthesized, the optimized coordinates of the corresponding measurement points are obtained when the sum of the measurement errors is minimum, the original coordinates of the measurement points are replaced with the optimized coordinates, and then the more accurate coordinates of the measurement points in the measurement system are obtained; and finally, the effect of improving the measurement precision of the measurement system is achieved.

Description

technical field [0001] The invention relates to the field of measurement system calibration, in particular to a method, device, equipment and storage medium for calibration of coordinates of measurement points. Background technique [0002] In the measurement system, generally at least two known measuring points can be used to measure the position coordinates of the point to be measured. During the measurement process, it is necessary to obtain the precise coordinates of each known measuring point, so as to obtain the relationship between each point to be measured and The distance of the measuring point is known, and then the position coordinates of the point to be measured are calculated according to the coordinates of the known measuring point and the distance between each point to be measured and the known measuring point. Such a measuring system must accurately measure the exact coordinates of each known measuring point in advance. In order to improve the accuracy of th...
