目前平行光管视差检测多采用五棱镜法，由于人工读数存在较大的误差，提出了一种基于圆形匹配与数据融合的大口径平行光管视差自动检测方法。选用高清相机对大口径平行光管分划板成像，通过大津法二值化、开运算去滤波、边缘检测、圆形匹配、数据融合等方法得到图像圆心所在位置；最终给出视差计算结果。视差计算的过程中，可以实现多点测试，即可以给出视差变换的曲线，可以给平行光管的调校带来方便。试验表明自动视差测量装置的检测结果准确，并具有良好的可重复性。

At present, the method we often use to measure the parallax of Large-aperture collimator is pentaprism method. Since artificial reading caused error, a kind of automatic inspection system for parallax of large-aperture collimator was put forward based on circular matching and data fusion. A high-definition camera was used to collect the image for large-aperture collimator. The center of the circle was found through OTSU, filtering, edge detection, circular catching and data fusion. A calculation result for parallax was given finally. In the process of calculating parallax, it can do more testing, so the curve of the parallax can been given out, which will make the collimator calibration convenient. Test results of automatic inspection system for parallax are proved to be accurate, and the automatic inspection system has good repeatability.
