Problems solved by technology

Such an operation method is cumbersome and inefficient; there is no prompt information for the connection between rigid bodies, and errors are prone to occur during labeling. At the same time, due to errors during reconstruction, it cannot be guaranteed that all feature points participating in labeling are correctly reconstructed. Feature points
Therefore, the traditional human-computer interaction projection cannot realize real-time three-dimensional interaction guided by human motion.

Embodiment Construction

[0090] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0091] The video image projection unit 1 adopts a high-lumen, short-focus projector.

[0092] In order to meet the requirements of precision and sensitivity, the near-infrared light field projection in the video image projection unit 1 adopts the active contour technology. By using the infrared LED light matrix to form a "wall" of the near-infrared light field, the camera that senses the infrared light faces the "wall" of the near-infrared light field. wall".

[0093] The image acquisition unit 2 collects the movement and posture information of the human body between the infrared camera and the "wall".

[0094] The image acquisition unit 2 includes the following equipment, (1) a camera with a rotating device, which can freely rotate the camera at an angle of + / -90 degrees horizontally and vertically; (2) an infrared LED lamp matrix group ...

Abstract

The invention provides a system and a method which can fully and really realize the three-dimensional interaction projection. In the invention, a camera group acquires visible outline surfaces of a human body and other objects in a certain projection area, an image processing unit carries out separation, correction and three-dimensional reconstruction to acquired images of the image processing unit, the acquired images are transmitted into a three-dimensional interactive unit through a communication unit, and three-dimensional interaction can be realized in the projection area. According to the invention, a human body chain-shaped model is automatically set up by using a computer vision technology, and gestures and actions of the human body can be automatically identified, are analyzed according to a semantic database, and then are then interactive with the three-dimensional interactive unit in real time.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to an interactive projection system and method. Background technique [0002] With the continuous development of microelectronics technology, computers have been widely used in various fields of human society, and various human-computer interaction equipment and methods have emerged, mainly completing the following functions: industrial management control function; auxiliary design function; display output function; the function of editing text data, image data and streaming media data; entertainment functions such as audio-visual and games. According to human-computer interaction equipment can be divided into the following categories: [0003] 1. Interaction through sensors: mainly includes production process management of production line products, product quality control, and reverse engineering. [0004] 2. Interaction through specific tools: mainly includes computer-a...
