单目视觉测量系统中目标位姿对图像点灵敏度影响的研究
Effects of the Target Position on the Sensitivity of Image Point in Monocular Visual Measurement System

通过研究单目视觉测量系统中不同位姿物体姿态测量的灵敏度，找到对图像点灵敏度影响的因素和各自占有比例。给出了灵敏度分析的理论模型，通过设计影响图像点灵敏度相关因素的数值分析实验，得出图像点灵敏度与靶板倾角及物距成反比，最大数值灵敏度最大值对应的处的靶面目标姿态，始终位于相机主方向光轴方向上。
Through the sensitivity study in different object's pose in monocular vision measurement system, the influencing factors and the corresponding proportion can be found. At first, a theoretical model for the sensitivity of image point is proposed in this paper. Then a series of the numerical analysis experiments are designed. The results show that the sensitivity of image point is inversely proportional to the target plate angle and the distance between the camera and the object. The object's pose will always be in the direction of the camera's optical axis when the sensitivity of image point reaches the maximum value
