【摘要】 充分利用光纤传像束可弯曲以及长距离传输图像等优点,用它代替传统的光学系统,结合DLP(Digital Light Process-ing)数字投影技术,解决受限空间内小物体三维形貌测量系统的结构光投射问题,研制了具有普遍适应性的小型可编程结构光投射器.构建了结构光投射系统,投射终端直径13 mm,长度40 mm,实现了小型化,系统可通过计算机编程控制投射出包括点、点阵列、线、多线、十字线和同心圆等多种模式的结构光条纹,验证了设计的可行性.更多还原

【Abstract】 The fibre image bundle has many advantages,such as direction changing and long distance image transmission without extra optics.Using of fibre image bundle rather than traditional fixed optical system,combining with digital light processing(DLP) technique,a new miniaturized programmable patterns projector with universal flexibility is developed to solve the structured light projection problem of 3D surface profilometer for small objects within a limited space.A structured light projection system is set up,which can project multi-mode fringes by programming,including,e.g.,dot,dot matrix,single line,parallel lines,crosshair and concentric circles,etc.The end dimensions of the projection unit are φ13mm×40mm.The possibility of the design is proved.更多还原
