在图形处理系统问世之前,大量的图形输入,依靠平板数字化仪,用手扶跟踪的方法,一点一划地完成,精度差,效率低。本系统的研究成功,适合国情,软硬件齐备,经济实用。其特点:(1)自成系统,实用性强,价格低,性能价格比高,便于推广;(2)硬件设计突破传统束缚,以简代繁,以很少的硬件投入,获得同样以至更好的效果。如扫描鼓的无过渡拖动和脉冲调速,省去了两套精密传动系统,大大简化了结构和电路;拖动扫描头的
Before the advent of the graphics processing system, a large number of graphics input, rely on flat-panel digitizer, with the hand tracking method, the little by little to complete, poor accuracy, low efficiency. The research of this system is successful, suitable for the national conditions, complete hardware and software, economical and practical. Its features: (1) self-contained system, practicality, low price, high performance-price ratio, easy to promote; (2) hardware design to break the traditional shackles to simplify the traditional, with little hardware investment, access to the same and more Good results. Such as scanning drum without dragging and pulse speed control, eliminating the need for two sets of sophisticated transmission system, greatly simplifying the structure and circuitry; Drag the scanning head
