摘要
为了实现对复杂物体三维外形的快速测量目的,首先设计了一套基于结构光的高速测量系统,该系统主要由高速投影模块和图像采集模块组成;然后采用一种基于绝对相位的编码和解码方法,实现绝对相位的测量,从而解决了复杂形体的三维测量过程中的二义性问题。最后,对所给系统进行了三维测量的实验验证,证明该系统精度可达到0.11mm,实验结果表明系统的精度和速度适合高速三维测量。
To realize the rapid 3D profile measurement of complex shape, a high-speed measurement system based on structured light was designed first, which is mainly composed of high-speed image projection and capture modules. Then, an absolute phase encoding and decoding strategy was used to achieve absolute phase measurement, resulting in the avoidance of ambiguity for the complex shape. Last, the proposed 3D measurement was tested and the result shows the accuracy can reach up to 0. 14 mm. The proposed system is conclusively appropriate for high- speed 3D measurement.
