摘要
提出了一种图像畸变校正与帧差法相结合的运动目标检测方法。首先利用实验测量和曲线拟合的方法对光学成像系统的畸变进行测量校正, 以满足运动目标检测的精度要求;然后将畸变校正方法应用在实时获取的视频图像帧中, 利用帧差法实现光学成像系统旋转运动时的运动目标检测。实验表明, 该算法可行、抗噪性好, 能够满足实时性需求。
Abstract
A method of moving object detection combined image distortion correction with frame difference is proposed. Firstly, the distortion of the optical imaging system is corrected by experimental measurement and curve fitting method for meeting the accuracy requirement of moving object detection. And then the distortion correction method is used in the captured image frames. As thus, the object detection is completed by frame difference method. Experiments show that the proposed method which meets real-time requirements is effective and has good noise immunity.
