摘要:

针对现有的距离测量方法仅能测量距离,功能较为单一的问题。提出一种基于关联成像和图像质量评价的距离测量方法,其可达到测量距离和成像的目的。通过实验测量检测光路光强,由计算机模拟不同传播距离参考光路光强,将两路光强做相关运算获得一系列目标物体图像,用峰值信噪比评价图像质量,峰值信噪比最大的图像对应的参考距离即为测量值。文中利用Matlab设计了相应的实验,验证了文中方法达到了获得目标物体图像和准确测量的效果。

关键词: 关联成像, 距离测量, 峰值信噪比

Abstract:

Existing distance measurement methods are capable of only distance measurement.An effective distance measurement method based on correlation imaging and image quality evaluation that can measure distance and image is proposed.The detection intensity is obtained from experiments,and the reference intensity of different propagation distance simulated by computer.A series of images can be obtained by calculating correlation of above two intensities.The peak signal to noise ratio (PSNR) is employed to evaluate the quality of images.The reference distance of image of maximal PSNR is the measured distance.Matlab experiments show the method can accurately measure distance and obtain the images.

Key words: correlation imaging;distance measurement;PSNR
