Various manifestations of instrument measurement errors

During the installation and use of instruments and meters, due to improper operation, unreasonable adjustment and other reasons, the measurement error is too large. The following summarizes some of the most common manifestations of measurement errors:

(1) Missing data collection or data density does not meet requirements. Using this incomplete data for point cloud fitting has large errors and it is difficult to achieve the required measurement accuracy.

(2) The results of data collection on the same surface are presented as multi-layered point clouds. This situation often occurs when the measured object is a large workpiece or the workpiece is a transparent object.

(3) The data collected by a single frame is inaccurate and affects the overall measurement accuracy.

(4) Accumulation error is too large, which makes the measurement result obvious deviation.

(5) Point cloud splicing errors result in larger measurement errors.

(6) Excessive data on large points (noise) in the measurement results.
