Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] A human-computer interaction calibration device based on infrared camera-visible light projector ( figure 1 (shown) includes a computing device (computer or computing chip), a visible light projector, an infrared LED lamp, a left infrared camera, a right infrared camera and a projection surface. Use the infrared camera to obtain the three-dimensional shape of the human body, and combine the three-dimensional data with the frame of the projector through the pose relationship between the infrared camera and the visible light projector, and realize real-time human-computer interaction by combining with the predefined rules.

[0030] Specifically include the following steps:

[0031] The first step is to calibrate the system parameters

[0032] Calibration of system parameters needs to use such as figure 2 The calibration display device of the human-computer i...

Abstract

The invention discloses a human-computer interaction system and device based on an infrared camera-visible light projector. An infrared camera is used for obtaining the three-dimensional form of a human body, a pose relationship between the infrared camera and the visible light projector is used for combining three-dimensional data with the picture of the projector, and real-time human-computer interaction is realized through combination with a pre-defined rule. By use of the system and the method, two infrared cameras are used for obtaining three-dimensional information, an information amountis rich, the system and the method can be more flexibly applied, and in addition, other contact type equipment is not required; the infrared camera and an infrared LED (Light Emitting Diode) are combined to avoid the interference of ambient light and projection light, and a detection process is more accurate; and through calibration, pose transformation between the infrared camera and the visiblelight projector is realized, and finally, an interaction function with the projector is realized.

Description

technical field [0001] The invention belongs to the field of optical three-dimensional measurement, and provides a human-computer interaction system and device based on an infrared camera-visible light projector, which uses an infrared camera to obtain the human body shape, and realizes real-time man-machine interaction through the relationship between the infrared camera and the visible light projector interact. Background technique [0002] Human-computer interaction technology refers to the technology that realizes the dialogue between human and computer in an effective way through computer input and output devices. [0003] Human-computer interaction technology includes that the machine provides a large amount of relevant information and prompts for instructions through output or display devices, and humans input relevant information to the machine through input devices, answer questions and prompt for instructions. Human-computer interaction technology is one of the im...
