The invention provides a three-dimensional hand gesture recognition device and a three-dimensional hand gesture recognition method. The three-dimensional hand gesture recognition device comprises two infrared cameras, an image collecting unit, an infrared light emitting diode, an infrared light emitting diode driving unit, an arithmetic unit and a hand gesture recognition unit; the two infrared cameras are arranged upwards and are electrically connected with the image collecting unit, the infrared light emitting diode driving unit drives the infrared light emitting diode to emit light, and the arithmetic unit is electrically connected with the image collecting unit, the infrared light emitting diode driving unit and the hand gesture recognition unit. The infrared light emitting diode emits light to provide back light, the image collecting unit collects hand gesture image data through the infrared cameras and sends the data to the arithmetic unit, binaryzation, edge extraction, two-dimensional finger location and three-dimensional position location processing are conducted on the data, and then the data are sent to the hand gesture recognition unit to achieve hand gesture recognition. According to the three-dimensional hand gesture recognition device and the three-dimensional hand gesture recognition method, infrared lighting and the infrared cameras are adopted, interference of visible light is avoided, the upward cameras shoot images so that interference of a background can be avoided, and reliability of hand gesture recognition is further improved.
Description
technical field [0001] The invention relates to gesture recognition technology, in particular to a three-dimensional gesture recognition method for a three-dimensional gesture recognition device. Background technique [0002] At present, gesture interaction technology has been widely used in the field of human-computer interaction. The existing technology of gesture interaction technology mainly includes two-dimensional gesture recognition based on a single camera and three-dimensional gesture recognition based on infrared structured light, such as Microsoft's product kinect. Two-dimensional gesture recognition based on a single camera has no depth information in operation, and can only recognize relatively simple two-dimensional gesture information; three-dimensional gesture recognition based on infrared structured light is costly to implement, and the operation accuracy has certain defects. [0003] Therefore, the prior art still needs to be improved and developed. Conte...
