Problems solved by technology
[0015] The technical problem to be solved by the present invention is to provide a method and system for splicing screens to change the image size according to the distance of the viewer, aiming at the traditional large splicing screens that are only suitable for long-distance viewing. When approaching the screen, the image information cannot be fully viewed. The sensor on the splicing screen senses the distance and size of the approaching human body, and selects a superimposed window on the splicing screen to display the image after the original image information is scaled down for close viewing. screen complete image information provides convenience

The invention relates to the technical field of commercial splicing display screens and discloses a method and a system for changing an image dimension according to a watcher distance. The method comprises the steps of monitoring whether a distance between a human body and the splicing screen is not greater than a preset distance or not in real time, acquiring position information of the human body when monitoring that the distance between the human body and the splicing screen is not greater than the preset distance, calculating a corresponding display image dimension according to a preset position and an image display scale rule, and displaying zoomed full image information in the corresponding position of the splicing screen via a superposition window according to the calculated display image dimension. The method and the system solve the problem that the traditional large splicing screen is only suitable for long-distance watching and a user cannot completely watch the image information when the user is close to the screen; a sensor on the splicing screen induces the distance and the dimension of the oncoming human body; and the superposition window is selected on the splicing screen to display a proportionally zoomed-out image of the original image information to provide convenience for watching the complete image information of the splicing screen in a short distance.
Description
technical field [0001] The present invention relates to the technical field of splicing display screens, in particular to a method and a system for changing the image size of a splicing screen according to the distance of a viewer. Background technique [0002] With the rapid development of display technology, splicing screens have emerged as the times require. Because of their large-scene display effects, they can bring users an immersive visual experience. Therefore, splicing screens are widely used in exhibitions. [0003] Since the size of a single display screen itself is limited, in order to achieve super large screen display, splicing screen technology came into being. The splicing screen uses multiple display screens to form a large display screen, and each display screen displays an image. Part of the display screens arranged in a matrix can display a large image together, and can also display different images on separate screens; the splicing screen is widely used ...
