Abstract

The invention discloses a gesture error correction method, system and device in an augmented reality environment. The method comprises the following steps: firstly, acquiring a first gesture depth mapand gesture depth information of a hand; judging whether the current gesture is recognizable or not by utilizing a gesture recognition model; when the gesture depth map cannot be identified, determining the minimum feature distance of the current second gesture depth map according to the Hausdorff distance, determining a third gesture depth map through the Hausdorff distance, and finally, inputting the third gesture depth map into the gesture identification model, so that gesture error correction is realized. The system comprises an information acquisition module, a preprocessing module, a first input module, a judgment module, a minimum feature distance determination module, a third gesture depth map determination module and a second input module. The device comprises a processor and a memory connected with the processor, and the processor can execute the gesture error correction method. Real-time performance and accuracy of gesture error correction can be greatly improved.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular to a gesture error correction method, system and device in an augmented reality environment. Background technique [0002] Augmented reality is also called AR (Augmented Reality). With the development of human-computer interaction technology, augmented reality, as a technology to enhance the interactive ability between reality and virtual reality, has attracted more and more attention. In the current augmented reality technology, most of them are based on wearable devices such as data gloves or gesture recognition sensors to complete the fusion of real hands and virtual scenes. In the process of gesture recognition, there will be some inaccurate recognition. Gesture error correction in technology is an important issue. [0003] At present, a commonly used gesture error correction method is a recognition method based on the Hidden Markov Model (HMM). Specifi...
