基于单目视觉下的手势识别技术一般由手势建模、特征提取、手势匹配等几个关键技术构成。手势跟踪算法目前主流的是粒子滤波算法和Camshift算法。系统采用Camshift算法,将人手图像由RGB空间转换到HSV空间后,在HSV空间利用半自动预定义模板颜色对人手进行分割,并对其进行改进实现多目标跟踪,由于Camshift算法为半自动算法,在对手势进行跟踪前需对手势进行手动标定,系统采用了手势跟踪与手势识别技术结合的方法,改进了Camshift算法,解决了Camshift的半自动问题和实现多目标跟踪,实现双手的手势识别。
基于單目視覺下的手勢識彆技術一般由手勢建模、特徵提取、手勢匹配等幾箇關鍵技術構成。手勢跟蹤算法目前主流的是粒子濾波算法和Camshift算法。繫統採用Camshift算法,將人手圖像由RGB空間轉換到HSV空間後,在HSV空間利用半自動預定義模闆顏色對人手進行分割,併對其進行改進實現多目標跟蹤,由于Camshift算法為半自動算法,在對手勢進行跟蹤前需對手勢進行手動標定,繫統採用瞭手勢跟蹤與手勢識彆技術結閤的方法,改進瞭Camshift算法,解決瞭Camshift的半自動問題和實現多目標跟蹤,實現雙手的手勢識彆。

The gesture recognition technology based on monocular vision is usually constituted by the key technologies of gesture modeling,gesture segmentation,feature extraction and gesture matching.The most popular gesture tracking algorithms based on monocular vision are the particle filtering algorithm and Camshift algorithm.This system converts the hand images from RGB space to HSV space,segments the hands using templates predefined color value,makes some improvements and realizes multi-objective target tracking.Because Camshift algorithm is semi-automatic,the gesture must be calibrated manually before being tracked.The system combines the gesture tracking and gesture recognition technology,improves the Camshift algorithm,solves the problem of being semi-automatic,and realizes multi-objective target tracking and finally realizes the gesture recognition of both hands.
