针对手动跟踪设备激光测距机对空中运动目标距离准测率低而难以建立目标航路的问题,提出了一种激光轴同步偏转控制技术。用摄像机摄取目标图像,并由图像处理器求出跟踪误差,控制测距机中的某些小型零部件偏转,同步改变激光发射和接收光轴,有效补偿跟踪误差,以达到提高距离准测率的目的。详述了激光发射和接收光轴变化的原理和计算方法以及激光发射与接收轴同步偏转控制技术的原理和实现方法,分析了使用该技术对跟踪仪性能的影响,介绍了室内台架试验和室外跟踪试验的试验情况,并由试验结果得出了在手动跟踪设备采用本技术后距离准测率可明显得到提高的结论,具有较高的应用和推广价值。
Aimed at the problem that the laser ranging machine for manual tracking equipment has low target-to-flight ratio of air moving target and it is difficult to establish the target route, a synchronous control method of laser shaft deflection is proposed. Using the camera to capture the target image, and the tracking error obtained by the image processor to control some small parts of the rangefinder deflection, synchronous laser emission and receive optical axis change, the effective compensation of tracking error in order to improve the accuracy of the distance the goal of. The principle and calculation method of laser transmitting and receiving optical axis variation and the principle and implementation method of laser emitting and receiving axis synchronous deflection control are described in detail. The effect of using this technology on tracker performance is analyzed. The indoor bench test and Outdoor tracking test of the test situation, and from the test results obtained in the manual tracking device after the adoption of the technology quasi-distance measurement rate can be significantly improved conclusion, with high application and promotion value.
