摘　　要：精密水准测量是国家建设的重要基础性工作。然而目前常用的条码水准尺携带极为不便,且存在条码易损坏、各型号水准尺条码之间不能通用、夜间识别困难等多种问题。本文提出了一种基于投影技术的可折叠条码水准尺的设计思想,通过数字光处理投影设备,把条码投影到具有良好显示性能的折叠面板上,在满足测量精度的前提下实现可折叠功能。Precise leveling is an important basic work in national construction.However,the bar-code staff commonly used at present is extremely inconvenient to carry,and there are other problems,such as the bar code is easy to be damaged,each type of bar code cannot be used universally,and it is difficult to identify at night.In this paper,a design idea of foldable bar-code staff based on projection technology is presented.Through digital light processing projection equipment,the bar code is projected onto a folding panel with good display performance,and the foldable function is realized on the premise of satisfying the measurement accuracy.
