数字近景摄影测量在河工模型试验中的应用

Application of Digital Close-Range Photogrammetry to the Deformation-Observing for Watercourse-model

传统常规的测量手段具有工作量大、效率低、费用高、精度低等多方面的问题。介绍了基于非量测数字相机的近景摄影测量方法,通过解算观测点的空间三维坐标,结合平甸河河工模型试验的实例进行分析,结果表明,数字近景摄影精度高,能很好地解决河工模型试验的测量问题。

There is many workload, low efficiency, highly cost, low precision, etc. and many problem in traditional survey technology. The author describe the method of close-range photogrammetry based on no measure digital camera, through calculate three-dimensional coordinate of observation point, unite example of watercourse-model to analyse, the result explain digital close-range photogrammetry have highly precision, it can solve the survey of watercourse-model.
