监控摄像机安装优化研究

摘要

根据目前采用的摄像机成像公式，针对监控摄像机在实际运用中的安装位置、角度及焦距的选择等问题给出新的计算模型，并与传统平面成像的计算模型进行对比分析，在新的模型中考虑了摄像机与监控对象之间的夹角对成像的影响，从而弥补了监控摄像机传统水平成像公式的不足，通过计算分析研究，给出不同焦距摄像机在不同安装角度下对应的与目标的水平距离。%The paper presents a new calculation model based on the current camera imaging formula and against the selection of installation position, angle and focal length of surveillance cameras in practical application. Compared with the calculation model using traditional planar imaging method, the paper considers the effect of the angle between the cameras and monitoring object on the imaging in the new model, so as to make up the shortage of the traditional planar imaging formula. It also gives the corresponding horizontal distances of cameras with different focal lengths at different installation angles to the objects, through the calculation and analysis.
