摘　　要：针对基于视觉测量中激光器阵列辅助靶标投射模式切换及光条位置调节稳定性差、效率低,无法满足实际测量需求的问题,分析视觉测量中不同阶段对激光辅助靶标的投射及调节需求,同时考虑设备紧凑性、实用性及可靠性,设计加工1套激光器阵列调节装置,利用工作站及NI计数器驱动多台步进电机实现激光器独立及协调控制,最后根据调控需求及硬件装置基于LabVIEW开发相应的控制系统。研究结果表明:该装置及系统工作稳定,具有良好的调控效率和鲁棒性,实现了激光器阵列辅助靶标的高效自动化调节,为提高视觉测量效率奠定了良好的基础。For the problem of poor stability and low efficiency in changing the laser array aided targets including the laserprojection pattern and the position of stripe, the projection and adjustment demand of aided targets in the visual basedmeasurement were analyzed. Considering the compactness, practicability and reliability of the device, a set of the laserarray adjustment device was designed and processed. Independent and coordinating controls of the laser array wereaccomplished by driving multi-motor through a workstation and NI counter. According to the adjustment ＆ controldemand and hardware device, the corresponding control system was developed using LabVIEW. The results show that thedevice and system have the following features： good stability, high efficiency and good robustness. The system canachieve the efficient automatic adjustment of the laser array, which lays a good foundation for improving the efficiency ofthe visual based measurement.
