摘要: 为了实时准确地测出运动物体的速度,提出了一种基于单目视觉测量运动物体速度的方法。该方法采用便携式摄像机对运动小球进行视频采集,以VS2010平台下的开源库OpenCV为开发平台,利用帧差法对运动目标进行检测。所设计的测速算法能够实现对运动小球的水平速度和垂直速度的检测。实验证明,所提测速方法能有效地测出运动物体的速度,且准确度比较高。

关键词: 单目视觉,摄像机,Open CV,帧差法

Abstract: In order to accurately measure the velocity of moving object in real time,this paper presented a method for measuring the velocity of moving objects based on single hand-eye vision.In this method,a portable camera is used to capture the moving ball,taking VS2010 platform OpenCV as the development platform,and moving object detection based on frame difference method is realized.In this paper,the velocity measurement algorithm can realize the detection of the horizontal velocity and vertical velocity.Experiments show that this method can effectively measure the velocity of moving objects with high accuracy.

Key words: Single hand-eye vision,Portable camera,Open CV,Frame difference method
