摘　　要：针对柔性视觉测量系统的应用需求,根据介绍了基于线结构光视觉传感器实现棱线测量的相关技术,创新性地研究了采用线结构光视觉传感器实现空间圆孔测量的原理、方法,并对空间圆孔中心坐标的测量数学模型进行了详细地推导。基于线结构光视觉传感器实现棱线和空间圆孔测量的相关技术已经在江淮汽车厂C926汽车生产线上得到应用,采用双机器人形式对84个测量点进行了在线测量,取得了很好的测量应用效果。To meet the applied demands of flexible vision measurement system, the technology of ridge feature measurement with Line-structured light sensor is presented summarily. Moreover, innovative measurement principle and implementation method for spatial hole parameters are investigated using line-structured light vision sensor in the paper. Through the detailed research procedure,the math model for eenter coordinates resuhion of spatial hole is deduced. The discussed technolo gies have been proved and applied successfully in the C926 car body product line of JAC factory. The flexible vision measurement system for C926 car-body product line of JAC factory adopts two industrial robots for implementation of 84 points measurment on-field.
