| 摘 要： | 提出了一种基于激光光斑检测的数码相机测距方法,在数码相机上加装一个激光器,使激光光束与相机镜头的光轴平行,对拍摄到的数码相片中的激光光斑进行检测,再根据透镜成像的物像关系实现距离的测量.研究了利用LoG滤波器对激光光斑进行增强的方法,实现了背景灰度值大于光斑灰度值情况下的光斑分割,从而实现激光光斑的位置检测.并进行了实验研究,实验结果表明,采用本文提出的方法实现对物体距离的测量是可行的.

| Abstract: | In this paper we proposed a distance measurement method using digital cameras based on laser spot detection.We need to install a laser in the digital cameras,let the laser beam parallel to the optical axis of the camera lens,detect the position of the laser spot in the digital photos,and then we can obtain the distance between the object and the cameras according the imaging theory of lens.The laser spot enhance method using LoG filter was studied.The experiments were performed,and the results showed that t... |
