摘　　要：在某姿态测量系统中,伺服系统控制经纬仪在方位和俯仰两个自由度运动对目标进行实时跟踪。测量分站主控计算机首先通过接收外部引导信息快速将目标引入捕获电视视场,当脱靶量信息稳定后切入电视跟踪模式。当目标位置超出捕获电视作用距离后,重新切换到外引导模式,并进行必要的地球曲率修正,保证测量电视系统对目标的连续成像。实际应用证明,多种引导源可以相互补充,扩展系统的捕获和跟踪能力,提高跟踪精度。In a certain gesture measurement system, under the control of servos-control system, the opto-elec- tronic theodolite needs to move to trace the target firmly. In order to capture the target into the TV-field quickly, the center controlling computer in measurement station receives guiding information to apply outside-guide mode first, then apply TV-tracking mode when the TV-offset information is steady, after the target beyond the TV scope, the controlling computer apply outside-guide mode again with necessary earth curvature correction. Practice result shows that multi-guiding source can reinforce each other and extend the capturing and tracking ability, improve the tacking precision.
