摘要
倾斜摄影测量仪包含一个下视相机和若干个侧视相机,侧视相机焦距的合理选定对侧视影像分辨率和侧视相机作业效率的提升具有决定性作用。本文首先介绍了侧视影像分辨率数学模型,然后基于该模型提出了侧视相机作业效率评价模型,最后通过一个实例详细论述了侧视相机焦距选定方法,充分验证了采用侧视影像分辨率数学模型和侧视相机作业效率评价模型进行相互制约的方法的正确性。此外,本文在侧视相机其他参数的选定方法研究方面具有借鉴意义。
The inclinometer consists of one down camera and several side view cameras,the reasonable selection of the focal length of the side view camera plays a decisive role in improving the resolution of the side view image and the working efficiency of the side view camera.This paper first introduces the mathematical model of side view image resolution,then puts forward the evaluation model of side view camera operation efficiency based on the model,and finally discusses the selection method of side view camera focal length in detail through an example,which fully verifies the correctness of the method of mutual restriction between the mathematical model of side view image resolution and the evaluation model of side view camera operation efficiency.In addition,this paper can be used for reference in the selection of other parameters of side view camera.
