摘　　要：利用手机摄像头,通过改变摄像设备的焦距,对比两幅不同焦距下图片的模糊度,精确计算目标物体的距离,该方法同样适用于立体物体的距离测距。该方法将被测区域的图片量化为81个小图片,对每个图片采用边沿提取模糊测距技术来计算距离大小。利用高斯融合算法将该81个子图片的计算结果进行融合,最终得到被测立体物体到摄像头的距离。This paper based on mobile phone camera,by changing the focal length of the camera device,compared to two picture under different focal length of ambiguity,the precise distance of target object,this method also could apply to the 3D object distance range.This method to quantify measured area of pictures as 81 small images,for each image edge extraction of fuzzy distance measuring technology is used to calculate the distance.Using Gaussian fusion algorithm to the 81 child image fusion,the calculated results of the resulting measured 3D objects to the distance of the camera.
