| 摘 要： | 数码相机通过将景物取样成一系列像素来记录景物,而且每个像素的亮度取决于景物接收的光通量———照度。基于这一原理进行了闪光灯投影系统照度分布测试实验。首先通过数码相机采集被照物面的灰度图,然后用Photoshop图像处理软件和Matlab软件对图片进行量化分析处理,最终得到了闪光灯投射系统的照度分布情况。该测试方法简单、新颖,测试精度可满足工程应用需要。

Illumination distribution measurement of flashlight cast system based on digital camera |
| |
| Abstract: | The digital camera records a object by sampling it into a number of pixels, each of whose intensity depends on the amount of light received by it --illumination. Based on this principle , illumination distribution measurement experiments of flashlight cast system are done. First,the digital camera grabs gray maps of the surface of the irradiated objects, and then image is analyzed quantitatively and processed by photoshop image processing software and Matlab, at last the indensity distribution condition of flashlight cast system is obtained. The test method is easy and original, and its measuring accuracy can satisfy the demand of engineering application. |
