Embodiment Construction

[0022] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0023] See figure 1 with 2 , shown in the figure is a multifunctional fusion processing system using a laser projector. The processing system is mainly composed of photoelectric sensing device, image sampling module, image threshold segmentation module, surface image calibration operation module, adaptive color correction module and other components. The image sampling module mainly decodes the input signal, and then pre-stores the decoded data in DDR. The curved surface image calibration operation module is to compress the image of the special-shaped image overflowing the graphic projection screen into the projection screen. Fusion image processing simply superimposes the overlapping parts of the two images, and performs dark field compensation and light leakage compensation of the image fusion zone.

Abstract

The invention discloses a laser projector multifunctional fusion processing system and method. The system includes a photoelectric sensing device, an image sampling module and an adaptive color correction module; the photoelectric sensing device is placed on the projector or a projection screen and used for sampling surrounding ambient light RGB data; the image sampling module is used for samplingoriginal image RGB data provided by external video signals; and the internal of the adaptive color correction module is established an image color adjustment program, according to the image color adjustment program, and correction can be performed on the original image RGB data by utilizing the ambient light RGB data, so that output image RGB data for external output can be formed. The advantagesof the system and method are that the problems of hard adjustment of white balance and image color cast existing in traditional fixed brightness output can be solved.

Description

technical field [0001] The invention relates to the field of laser projectors, in particular, a multifunctional fusion processing system and method for laser projectors. Background technique [0002] At present, the existing laser projectors have a fixed brightness output, and there are problems such as difficult adjustment of the white balance and color cast of the image. The reason is that the influence of ambient light on the projection output has not been fully considered. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of white balance adjustment and image color cast in the prior art, and provide a new multifunctional fusion processing system and method for laser projectors. [0004] In order to achieve this goal, the technical solution of the present invention is as follows: a laser projector multifunctional fusion processing system includes, [0005] A photoelectric sensing device, which is placed at the projecto...
