Abstract

The invention provides a measurement system, a measurement method, an evaluation method and a compensation method for a depth camera error. The measurement system for the depth camera error comprises a verifying device, a depth camera, a distance measurement device and a support, wherein the depth camera is used for measuring and obtaining a depth image of a measured plane; the measurement accuracy of the distance measurement device is higher than that of the depth camera; the support is used for fixing the depth camera and the distance measurement device and enabling measurement initial points / surfaces of the depth camera and the distance measurement device to be positioned in the same base line and directly face the measured plane. By adopting the measurement system provided by the invention, the measurement on the depth camera error can be realized, error and deviation can be calculated, and evaluation on the depth camera and compensation on the error can be carried out through the error and the deviation.

Description

technical field

[0001] The invention relates to the technical field of optical measurement, in particular to a depth camera error measurement system and evaluation method. Background technique

[0002] The depth camera can obtain the depth information of the target to realize 3D scanning, scene modeling, and gesture interaction. Compared with the currently widely used RGB camera, the depth camera is gradually being valued by all walks of life. When using the depth camera to measure the depth image of the target, clear and accurate depth information is an important indicator to measure the performance of the depth camera. However, due to the influence of temperature, light, and scene, the depth information obtained by the depth camera often has a large error. On the other hand, errors will inevitably occur during the manufacturing and assembly of depth camera components, which will also directly bring systematic errors to the measurement.
