Abstract | The invention discloses a combined wide-angled aerial digital camera system having functions of self checking and self stabilization, wherein, four cameras are arranged in pairs on a stable platform; each pair of cameras are in equivalent and relative tilt, and a combined wide-angled equivalent center projection imaging system is formed and rectified by a self calibration method. The stable platform stabilizes a primary optical axis of the equivalent center projection imaging system to a near-plumb direction by revolving shafts which are vertical to each other and a mechanical damping device;and then the primary optical axis of the equivalent center projection imaging system is further stabilized by an accelerometer, an axial gyroscope, electronic sensors such as a magnetic compass and the like, as well as an attitude angle correcting unit. The camera system of the invention can realize the miniaturization and light weight of the combined wide-angled camera and the stable platform thereof, has high precision |
