Analysis And Design For The Forward Motion Compensation Of LMK Aerial Survey Camera

In this paper, forward motion compensation technology for LMK Aerial Survey camera is discussed in detail.lt is illustrated that forward motion compensation is the key techonology for air photography with high resolution.At first, the history and the classification methods of Aerial Survey camera is introduced. In allusion to LMK Aerial Survey camera.this paper introduced the target of the Image motion compensation.This paper analyses the applied characteristic of Phase-locked loops(PLL) for the forward motion compensation technology of LMK Aerial Survey camera. According to the analysis , a new style PCB is produced.The realization by software for the forward motion compensation is discussed in this paper, which is realized by the TI prduction TMS320F240. The control effect is satisfactory. We could have it as the foundation for the Aerial Survey camera redesign.The performance of the collectivity is analysed finally, the effect of forward motion compensation is estimated. The equivalent residual image motion of the compensation control system is very small. Facts have proved that the design is simple, practical and feasible.
