Problems solved by technology
[0003] At present, due to various reasons, this interactive technology with good user experience has not been popularized on large-scale display screens or PC monitors on a large scale. One of the big reasons is that most of the current large-scale display screens or PC monitors None support touch, and replacing a monitor with touch will cost a fortune
Correspondingly, some existing touch technologies are difficult to enlarge in size, some cannot be applied to existing displays, and some cannot be applied on a large scale due to high cost.

The invention discloses an infrared camera three-dimensional imaging-based touch recognition method. The infrared camera three-dimensional imaging-based touch recognition method comprises the steps that an infrared camera is arranged on any frame of a screen in an attached manner, the screen is calibrated by the camera, the camera arranged on the frame of the screen is used for collecting images of behaviors such as clicking, touching, sliding and the like of a finger or a touch pen, and a special processor on the device is used for processing images to enable the finger or the touch pen to be three-dimensionally imaged, and judging the position and action of the touching point of the finger or the touch pen on the screen. According to the infrared camera three-dimensional imaging-based touch recognition method, the function of realizing a touch screen on any screen can be achieved, and the infrared camera three-dimensional imaging-based touch recognition method is simple to use, accurate to locate, and convenient to install and carry.
Description
technical field [0001] The invention belongs to the technical field of computer artificial intelligence, and more specifically relates to a touch recognition method based on three-dimensional imaging of an infrared camera. Background technique [0002] The advancement of technology makes the interaction between human and computer more and more close to the natural way of interaction, which is the "natural interaction" advocated by people. The easy human-computer interaction method of touch technology has been pushed to many fields. In addition to being used in personal portable digital products, it is also widely used in information appliances, public information, electronic games, office automation equipment and industrial equipment and other fields. Using touch technology, users only need to lightly touch the text or icons on the screen with their fingers to realize the interaction with the computer, making the interaction between humans and machines more intuitive and co...
