摘　　要：介绍了一种基于JQJY型经纬仪检定台的激光垂准仪校准装置的结构及特点,该校准装置是通过采用工业相机、分光棱镜、中性滤光片等改造原经纬仪检定仪的平行光管,并编制了相应的图像处理软件,实现了十字分划线与激光圆形光斑中心坐标自动定位,达到了垂准仪室内校准效果。The structure and characteristics of a laser-Plumb instrument accuracy calibration device based on JQJY model theodolite verification device.The device introduces the parallel light tube of the original theodolite detector by using industrial camera,spectroprism and neutral density filter,and prepares the corresponding image processing software to realize automatic positioning of cross di-vision line&laser circular spot center coordinate.Finally,the indoor calibration effect of the verti-cal alignment meter is achieved。
