基于移动端的“非受控”物体识别算法的实现

Realization of “Uncontrolled” Object Recognition Algorithm Based on Mobile Terminal

针对现有的物体识别方法在复杂环境下易受光照、角度、尺寸、复杂背景等“非受控”因素的影响,且识别率低、实时性差、占用内存大等问题,提出一种新的物体识别算法,并在此基础上实现了基于移动端的物体识别系统。该方法首先利用粒子滤波算法对检测范围进行加窗跟踪,接着用分水岭分割算法对物体进行分割,然后用HOG(Histogram of Oriented Gradient)算法提取物体特征,最后运用随机森林算法进行物体匹配。实验结果表明该方法能基于移动端在“非受控”的环境下进行较快速且准确的识别,从而证明了该方法的有效性。

Aiming at the problems that the existing object recognition methods are easy to be influenced by“uncontrolled”factors such as illumination,angle,size and complex environment,and have the problems such as low recognition rate,poor real-time performance and large memory consumption,this paper proposed a new object recognition algorithm,on which the object recognition system based on mobile terminal was realized.This method first employs particle filter algorithm to track the detection range by adding windows,and then applies the watershed segmentation algorithm to segment objects,then uses the HOG(Histogram of Oriented Gradient)algorithm to extract object features.Finally,the random forest algorithm is utilized to recognize objects.The experimental results show that this method can be used to identify the mobile terminal quickly and accurately in an“uncontrolled”environment.
