摘要
为满足优质助听器需求,设计了一种基于图像处理的高精度3D耳蜗扫描重建系统。系统基于单目视觉方案进行设计,DLP4500投射结构光对耳蜗模型进行扫描,相机高速抓取图片发送给PC机,PC机通过程序调用Opencv链接库函数,对接收到的二维图像进行处理,不断提取点云数据,对提取的点云数据利用三角网格重构算法进行重建。标准立方体的测试结果显示,整个系统的扫描精度在0.2mm以内,扫描时间为2分钟,在保证高精度的同时,运行时间相比同类设备有了很大提高,大大提升了生产效率。
Because it is designed for customized products of consumers,the users have high demand on the scanning accuracy of the whole system in terms of usage.In order to get the 3 Dcochlear scan results with high accuracy,this article designs a kind of high precision 3 Dcochlear scanning reconstruction system based on structure light.The hardware of the whole system is mainly composed of DLP4500 structure light generator TI and camera dots.The system is used to process the grating deformed image produced by the structural light projected onto the object,extracting the point cloud data needed,and then reconstructs the scanned object by using the triangular mesh reconstruction algorithm.The experimental data shows that the accuracy of the system is 0.2 mm,the scanning time is about two minutes.The designed system can meet the demand well.
