摘要
针对相似材料模型试验现有观测方法所存在的工作量大、自动化程度低等缺点,采用近景摄影测量系统进行相似材料模型试验的位移观测;分析了拍摄光照环境、拍摄位置、观测距离及布点方案等因素对近景摄影测量系统解算精度的影响。通过试验得到了最佳数据采集方案,进一步提高了系统的解算精度,是相似材料模型位移观测的有效方法。
In order to solve the problems of heavy workload and low automation of traditional surveying method in similarly material model experiment, close-range photogrammetry system was used to displacement monitoring in similarly material model experiment, some factors that influenced calculation precision of close-range photogrammetry were analyzed, which included luminous environment, position, surveying distance and points distribution scheme and so on.The best data collection scheme was put forward after experi-ment, the calculation precision was improved future, it was an effective method for displacement monitoring of similarly material model experiment.
