摘　　要：基于数字图像处理技术,通过圆形人工标志获取成像图片与实体对象之间的长度转换系数,实现了室内自由下垂拉索的线形识别,并将其线形识别结果与基于近景摄影测量原理和全站仪测量的结果进行对比,结果表明识别误差在毫米级,且优于基于近景摄影测量原理的线形测量方法。Based on digital image processing technology,the length conversion coefficient between the imaged picture and the physical object is obtained through the circular artificial sign,and the linear recognition of the free hanging cable indoors is realized.The linear recognition results are compared with those based on the principle of close range photogrammetry and total station measurement.The test results show that the recognition error is at the millimeter level,which is better than the linear measurement method based on the close-range photogrammetry principle.
