Embedded electronic distorting mirror system

technical field

The invention belongs to the technical field of image processing and relates to an embedded image real-time deformation device, which can be used in various leisure and entertainment places such as families, evening parties, exhibitions and restaurants.

Background technique

As we all know, different deformed images will appear in mirrors with different bending effects. People standing in front of these mirrors will be amused by the deformed images in the mirrors. Therefore, curved mirrors with such effects are vividly called "distorting mirrors". Traditional distorting mirrors are actually curved optical mirrors. Each mirror has only one deformation effect. If you want to see different effects, you need different distorting mirrors. Because distorting mirrors occupy a certain amount of space, this means that if you want to see more deformation effects, you must occupy more space and place more distorting mirrors. The types of deformation of traditional optical distorting mirrors in applications are limited by the space capacity.

The concept of "electronic distorting mirror" was mentioned in the 6th China Computer Graphics Conference in 2006, and Zhou Renqin et al. made a corresponding introduction in the document "Electronic Distorting Mirror: A Video Processing System for Digital Entertainment". Although this kind of electronic distorting mirror can solve the problem that the types of deformation of traditional optical distorting mirrors are limited by the space capacity, the technology mentioned in the literature is limited to the deformation of human faces, and the types of deformation are limited, and the realization platform is a PC. The application occasions and application effects of the electronic distorting mirror are discussed.

Below in conjunction with accompanying drawing, the present invention is described in further detail:

Referring to FIG. 1 , the present invention mainly consists of an imaging device, an image deformation device and a display device connected to each other. Among them: the imaging device is used for real-time imaging, and the image data is transmitted to the image deformation device through the general video interface; the image deformation device transmits the image to the display device through the general video interface after real-time deformation processing, and the general video interface includes analog composite video and digital video; the display device will display the deformed image in real time. When people stand in the field of view of the imaging device, they can see the deformed image on the display device at the same time. If they continue to stay in the field of view of the imaging device, they can also see the display device as time goes by. Different deformed images appear successively on the screen, and it can be seen that multiple different deformed images will appear simultaneously on the display device.

Referring to Fig. 2, the image deformation device is mainly composed of an image acquisition module, an image deformation module, an image output module and a human-computer interaction module connected to each other. The image data sent by the imaging equipment first enters the image acquisition module, which sends the received image data to the image deformation module in digital form; the image deformation module then translates, rotates and rotates the image data sent by the image acquisition module in real time. Its combination, in order to realize stretching, contraction, enlargement and reduction various deformation effects, and send the result after deformation to the image output module; The image output module sends the image data sent by the image deformation module to the display device for display, thereby achieving The display effect of the distorting mirror, in addition, this module can also control other output devices for display, storage, communication and printing operations; the human-computer interaction module establishes a communication channel between the image deformation device and the operator, and receives the system working status sent by the operator Configure information to control the working status of the image acquisition module, image deformation module and image output module.

The deformation sub-module performs image deformation according to the method described in the paper "Principle Warps: Thin-plate Splines and the Decomposition of Deformations" published by Fred L. Bookstein on IEEE Transactions on Pattern Analysis and Machine Intelligence in 1989. First determine a deformation reference origin in the field of view, and then determine the processing method of each image pixel relative to the reference origin according to the characteristics of the deformation function. The processing method includes removing pixels, translating pixels, inserting pixels and rotating pixels. After all pixels are processed, the deformation effect relative to the deformation function is processed. The control information of the deformation control sub-module includes the shape of the deformation, the duration of the deformation, the display order of the deformation, and the display mode of the deformation. For example, if the deformation style is set to four types: fat, thin, tall, and short, the display method is to first display the four deformations on the entire screen, and then display the four deformations in four areas in one screen at the same time, and set the duration to 15s respectively. , 20s, 10s, 10s and 25s, the display order is random. After the settings are confirmed, the corresponding distorting mirror effect will be displayed on the display device according to the determined settings.
