Projection control method, device and system, medium and electronic equipment

Abstract

The invention relates to a projection control method, device and system, a medium and electronic equipment. The projection control method comprises the following steps of: in response to a received projection instruction, acquiring a first color value of diffuse reflection light formed by diffuse reflection of ambient light through a projection surface and a second color value of current RGB of each set of projection equipment; determining a target gain coefficient of an RGB channel in each set of projection equipment according to the first color value and each second color value; and respectively distributing the target gain coefficient of the RGB channel in each set of projection equipment to the corresponding projection equipment, so that each set of projection equipment adjusts the gain of the RGB channel according to the corresponding target gain coefficient. In this way, the color temperatures of all the regions in the spliced picture can be kept consistent, and the impression experience of a user is improved. Moreover, the color temperature of each region of the spliced picture can be adjusted to be consistent at one time only by acquiring the first color value and each second color value once, so that the efficiency of color temperature consistency adjustment in the projection system is improved.

Description

technical field [0001] The present disclosure relates to the technical field of projection equipment, and in particular, to a projection control method, device, system, medium, and electronic equipment. Background technique [0002] Users' demand for large-screen display is becoming stronger and stronger. For example, some application scenarios need to project images of hundreds of inches. If only an ordinary projection device is used for projection, the brightness of the screen will be low, and the guarantee of large-size screens The cost of high-performance projection equipment that projects brightness is high, so most users choose to use multiple projection equipment to splice projection images to project large-size images. However, due to process or batch differences in filters, light sources, and even optical paths, the light projected by even the same batch of projection equipment will be different, and the consistency is poor. Therefore, when multiple projection devi...

Problems solved by technology

However, due to the process or batch differences of filters, light sources and even optical paths, the light projected by even the same batch of projection equipment will be different, and the consistency is poor.

Therefore, when multiple projection devices are used to splice projection images, the color temperature of each area of ​​the projection image may be inconsistent, and the user's visual experience is poor.
