Abstract

The boresight of the aerial remote sensing camera (ARSC) need to be elicited to the reference coordinate system of the satellite after the assemblage of the whole satellite. Because it is difficult to aim the boresight after finish fixing the camera to the satellite, the boresight must be elicited by a cube before the fixing. So the cube coordinate system can be transited to the reference coordinate system. The boresight of the camera is measured by a theodolite. The orientation of the boresight can be solved through measuring four angles of the CCD, the top left corner, the bottom left corner, the top right corner, and the bottom right corner, and then the spatial angle of the boresight can be solved. According to the traditional methods of the data processing after boresight measuring, the limitation has been analyzed by using the Mat lab software. The trace of motion of the theodolite is provided, while it is rotating horizontally with a vertical angle around the vertical axis and rotating vertically with a horizontal angle around the horizontal axis. Based on the vector combination theory, the normalized vector of the boresight can be obtained, so the spatial angle of the boresight can also be calculated. At last, this paper shows two applications in factual measuring.
