国内现有的电视跟踪系统,其人工捕获、引导目标,多采用单杆控制器,手轮或旋钮来操纵跟踪摄象头。本装置与其相比,具有以下特点: (1)操作简便,捕获目标的时间短,提高了系统的机动、灵活性。(2)缩短了操作人员的训练时间,降低了对操作人员的素质要求。(3)装置的线路和结构简单,成本低廉,光笔采用普通硅光电二极管,简单可靠便于 The existing domestic TV tracking system, its manual capture, guide the target, the use of single-pole controller, hand wheel or knob to manipulate the tracking camera. Compared with the device, the device has the following characteristics: (1) The operation is simple, the time for capturing the target is short, and the maneuvering and flexibility of the system are improved. (2) shorten the training time of the operator, reducing the quality requirements of the operator. (3) The device of the circuit and the structure is simple, low cost, light pen using ordinary silicon photodiode, simple and reliable
