pinhole imaging

The automatic tracking system using image sensor detects the position of the sun changes, design imaging body by the principle of pinhole imaging, then the sun projection into the spot image can be collected by the image sensor.

该自动跟踪系统采用图像传感器检测太阳位置变化，按照小孔成像原理设计一次传感器一成像机构，将太阳投影成可以被图像传感器采集的光斑图像。

According to the theory of perspective projection, the pinhole imaging model of a single-purpose is selected. And we research on the coordinate systems definition, the conversion relationship of the position offset and the angle rotation between the coordinate systems. 2.

根据透视投影理论，采用了单目的针孔成像模型，主要介绍各坐标系的定义和坐标系之间的位置偏移、角度旋转的转换关系。

This experiment demonstrates the theory of pinhole imaging.

这个实验是为了演示小孔成像的原理.
