Abstract

The invention discloses a projection equipment optical performance measurement device and method based on motion control. The device comprises a control processing system, a three-dimensional motion mechanism and a chroma meter, wherein the chroma meter is mounted on the three-dimensional motion mechanism, the control processing system is used for sending standard test image data to projection equipment, sending a motion control instruction to the three-dimensional motion mechanism, acquiring measurement data of the chroma meter and processing the measurement data to acquire measurement data in consistent with comparison conditions, the three-dimensional motion mechanism is used for doing motion according to the motion control instruction and making the chroma meter move to a designated point to carry out optical performance measurement on the projection equipment, and the chroma meter is used for carry out optical performance measurement on the projection equipment to acquire measurement data. The measurement device and the measurement method are advantaged in that optical performance of the projection equipment can be automatically measured, and optical performance measurement cost of the projection equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of optical performance measurement of projection equipment, in particular to a motion control-based optical performance measurement device and method for projection equipment. Background technique [0002] With the rapid development of technology and economy, projection equipment has become an indispensable role in educational presentations, business activities, government offices and home entertainment.
