摘要
为满足机器视觉测量基础算法研究需要大量素材的要求,提出用计算机模拟合成的方法获取测量用灰度图像的新方法。首先,对比分析常见三维造型软件的造型功能和摄像模块,确定采用三维造型软件造型与VRay插件配合提取图像;然后,具体研究VRay插件的参数设置与调整,获取用于测量的灰度图像;最后,用所获取的图像进行几何量的测量。实验结果表明,在保证物距相等前提下,测量精度可达1μm。合成的灰度图像能够满足机器视觉测量基础算法研究的需要。!
One method named image synthesis was proposed for gray image composition to meet the requirement that algorithm re -search of machine vision needed a lot of images .Firstly,two modules,i.e.,modeling module and camera module ,of some engi-neering software were compared and images will be obtained by using three-dimensional modeling software cooperating with VRay plug-in.Then,parameter setting and adjustment for VRay plug-in was studied.Lastly,measurement experiments were carried out by using synthetic images .The experimental results demonstrate that 1μm measuring accuracy is possible under the condition that the distance between calibration part and camera was equal to that between parts and camera .The synthetic images can be used for algorithm research of machine vision .
