Abstract

The invention discloses a projector projection quality detection method, which comprises the steps of: (1) controlling a projector to project a preset standard test image; (2) controlling a camera toshoot the standard test image projected by the projector so as to obtain a shot image; (3) receiving the shot image obtained by the camera, comparing a color difference value, a brightness differencevalue and a contrast difference value between the shot image and the standard test image; (4) and judging whether the color difference value between the shot image and the standard test image exceedsa corresponding color preset range, judging whether the brightness difference value exceeds a corresponding brightness preset range, judging whether the contrast difference value exceeds a corresponding contrast preset range, and outputting corresponding prompt information if so. The projector projection quality detection method can precisely judge the projection quality of the projector, and output the corresponding prompt information to remind relevant personnel to perform related processing. The invention further discloses corresponding detection equipment.

Description

technical field [0001] The invention relates to a detection method and detection equipment of a projector, in particular to a projection quality detection method of a projector and electronic equipment thereof. Background technique [0002] Classrooms in modern schools mostly use multimedia equipment with a large number of equipment, including projectors, microphones, speakers, etc. The projection quality of the projector will continue to decline, which will affect the teaching effect. Therefore, there is an urgent need for a method for detecting the projection quality of the projector and reminding relevant personnel in time of the projection quality of the projector and its electronic equipment. Contents of the invention [0003] The purpose of the present invention is to provide a method for detecting the projection quality of a projector and electronic equipment, which can detect the quality of the projection of the projector and provide relevant reminders in time when...
