Problems solved by technology
[0003] Since the projector projects images or videos directly onto the screen, the projection effect of the projected image displayed on the screen will be affected by the ambient light in the area where the screen is located. If the ambient light is too strong, the ambient light will cover the output of the projector. If the ambient light is too weak, the projected picture displayed on the curtain will be too dark, making it difficult for people to clearly obtain the information reflected in the projected image.

Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] see figure 1 , the system 20 for projecting fluorescent images includes a projection module 21 , a light detection device 22 and a processor 23 , and the processor 23 is connected to the projection module 21 and the light detection device 22 respectively. The light detection device 22 is used for detecting the illumination intensity of ambient light in the projection area of the projection module 21 . The light intensity of ambient light refers to the energy of visible light received per unit area. In addition to directly detecting the illumination intensity of the ambient light in the projection area through the light detection device 22, a projection environment image can also be taken by a lens device with an acquisition function, and then grayscale processing is performed on the image, by calculating the grayscale image The gray value o...

The invention discloses a method and system for fluorescence processing of projector images. The method includes acquiring a projection image; performing grayscale processing on the projection image to obtain a grayscale image; extracting a contour image from the grayscale image, and corroding the contour image. Expansion processing; detect the ambient light intensity of the ambient light in the projection area projected by the projection module, and perform dyeing and blurring processing on the image after corrosion and expansion processing according to the illumination intensity of the ambient light; combine the outline image and the dyeing and blurring processing The images are fused to obtain a fluorescence image; the projection module projects the fluorescence image to the projection area. Through the above method, the present invention can realize the projection module to project a fluorescent image, and the fluorescent image can be distinguished from the ambient light, making it convenient for the user to view the fluorescent image. In addition, the present invention can also adjust the fluorescence according to the illumination intensity of the ambient light in the projection area of the projection module. The degree of fluorescence of the image makes the fluorescent image more in line with the needs of the projection environment.
Description
technical field [0001] The invention relates to the field of projection technology, in particular to a method and system for fluorescent processing of projector images. Background technique [0002] A projector (also known as a projector) is a device that can project images or videos onto a screen, and the images or videos projected onto the screen are displayed several times or tens of times for magnification while maintaining clarity. It is convenient for people to watch and also gives people a wide field of vision. Therefore, projectors are very popular among users. [0003] Since the projector projects images or videos directly onto the screen, the projection effect of the projected image displayed on the screen will be affected by the ambient light in the area where the screen is located. If the ambient light is too strong, the ambient light will cover the output of the projector. If the ambient light is too weak, the projected picture displayed on the curtain will be ...
