Problems solved by technology

[0005] (1) This method is easy to cause some pixels to be lost at the connecting seam, and a sudden change occurs at the boundary of the two sub-images, which cannot achieve a good color transition;
[0006] (2) This method requires an optical modulation operation first, and then an electronic gain adjustment operation, and the gain adjustment operation requires manual setting and adjustment, which is not only time-consuming and laborious, but also cannot and cannot guarantee the accuracy of the adjustment

Embodiment Construction

[0052] The image processing method for seamless splicing of screens in the first technical solution of the present invention comprises the following steps:

[0053] S10: Take and store images of each gray level of the three primary colors of the spliced ​​screen, such as figure 1 As shown, the spliced ​​screen 102 is spliced ​​by four spliced ​​display units with a resolution of 1024*768;

[0054] S20: establishing a corresponding relationship between each pixel of the spliced ​​screen in the captured image and each pixel of the actual screen;

[0055] S30: According to the position correspondence in step S20 and the images of each gray level of the three primary colors in step S10, respectively establish a pixel gray value table storing images of each gray level of the three primary colors in the vicinity of the splicing seam;

[0056] S40: Reset the grayscale value in the pixel grayscale value table in step S30, and find the grayscale value corresponding to the reset graysc...

Abstract

The invention discloses an image processing method for realizing seamless mosaicing of mosaicing screens. The method of the invention comprises the following steps: S10: shooting and storing images of various gray levels of the three primary colours of the mosaicing screens; S20: establishing the position congruent relationship between pixels of the mosaicing screens in the shot images and the pixels of the actual screens; S30: establishing a pixel gray value form stored with the various gray levels of the three primary colours of the images in the regions near the seams; S40: resetting the gray value in the pixel gray value form in step S30; and S60: separating data of mosaicing units from the stored form in step S50 and transmitting the data to each mosaicing unit to be displayed. In addition, the invention discloses an image processing device for realizing seamless mosaicing of the mosaicing screens.

Description

technical field [0001] The invention relates to an image processing method for splicing screens, in particular to an image processing method and a device thereof which can realize seamless splicing of splicing screens. Background technique [0002] With the improvement of people's demand for display information transmission, the application fields of large-screen display have spread to various fields such as public display, transportation dispatching and commanding, weather monitoring, power and telecommunications monitoring, fire monitoring and commanding, and military commanding. [0003] Existing large-screen display technologies mainly combine multiple display units for splicing and display by stacking. The advantage of the splicing screen is that it can improve the system resolution of the display, increase the display area, realize the display of a complete picture on the entire display screen, and open a window at any position on the display screen, etc., but it also ...
