Embodiment Construction

[0047] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] The projection device mainly involved in the embodiments of the present invention may be a projector. Among them, a projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected and played with computers, DVD (Digital Video Disc, Digital Versatile Disc), game consoles and other devices through different interfaces. Corresponding to the video signal, the curtain here can be any device that can be used as a projection background such as a projection screen or a background wall.

[0049] refer to figure 1 , figure 1 It is a schematic diagram of the hardware structure of the projection device involved in each embodiment of the present invention. In the embodiment of the present invention, the projection device may include a processor 1001 (eg, Central Proc...

Abstract

The invention discloses a projection brightness adjustment method, device, equipment and computer-readable storage medium. The method includes: when capturing an obstruction entering the projection area, acquiring the obstruction image captured by the depth camera; based on the The occluder image and the pre-constructed coordinate system determine the occluder projection area of ​​the occluder on the projection area, wherein the projection area is all or part of the screen; The brightness is adjusted to the target brightness. Therefore, based on the image of the occluder captured by the depth camera, the projection area of ​​the occluder is determined, and the brightness corresponding to the projection area of ​​the occluder is adjusted to the target brightness, thereby reducing the power consumption of the projection lamp, saving electric energy and improving the performance of the projection lamp. service life.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to a projection brightness adjustment method, device, projection equipment and computer-readable storage medium. Background technique [0002] With the development of projection technology, the application of projection lamps is becoming more and more extensive. Generally, a projector is projected through a projection lamp, and the projection lamp often consumes more power. Some heat will be emitted during the projection process. In order to eliminate the impact of heat on the device, it is often necessary to use a fan to cool down, which requires more power consumption. Contents of the invention [0003] The invention provides a projection brightness adjustment method, device, equipment and computer-readable storage medium, aiming at saving electric energy and improving the service life of projection lamps. [0004] In order to achieve the above object, the present ...
