[0063] refer to figure 1 As shown, the first embodiment of the present invention is a projection distortion test method, which is mainly applied to DLP (Digital Light Processing), that is, digital light processing technology, and forms a projected image by projection. The projection distortion test method includes:

[0064] Step S10, obtaining the first image of the projected image. After the projection technique digitally converts the light signal, the projection light is projected on the surface of the screen to form a projected image, and the first image of the projected image is obtained by shooting, for example, through a test camera Take the projected image, generally the projected image is a color image, and any color image can be decomposed into three colors of red, green and blue, so it can be seen that the first image is also a color image composed of red, green and blue colors.

[0065] Step S20, color assignment is performed on the first image to distinguish the bo...

Abstract

The invention discloses a projection distortion test method, device and apparatus and a computer readable storage medium. A projection image is formed through projection. The projection distortion test method comprises the steps of obtaining a first image of the projection image; performing color assignment on the first image to distinguish the boundary of the first image; selecting a plurality ofboundary points of the boundary of the first image, recording corresponding color assignments among the plurality of boundary points, and obtaining a comparison series value; and comparing the comparison series value with a preset standard specification value, and judging whether the projection image distortion is qualified or not. According to the technical scheme, human participation can be avoided, and the consistency of projection image distortion judgment standards is ensured.

Description

technical field [0001] The present invention relates to the technical field of distortion testing of projection images, in particular to a projection distortion testing method, device, equipment and computer-readable storage medium. Background technique [0002] DLP (Digital Light Processing), that is, digital light processing technology. This technology first processes the image signal digitally, and then projects the light. Due to the digital processing, the image projected by the DLP module has optical distortion. Therefore, DLP After the projection module is assembled, it is necessary to test the projected image to determine whether it meets the set specifications and standards. At present, when judging the DLP module, it is all judged by naked eyes to see whether the image meets the requirements. , it is difficult to guarantee the consistency of the DLP module distortion judgment standard. Contents of the invention [0003] The main purpose of the present invention i...
