【摘要】 在视觉检测系统中,照明光源的好坏对系统最终的测量精度有很大的影响。本文首先推导了视觉检测系统的光强传递函数,然后对照明光源的光强、光照稳定性和均匀性等设计要点进行了分析,最后设计了能自适应调整光强的环形冷光源。为视觉检测系统的推广和使用提供必备的物质条件。更多还原

【Abstract】 Quality of illumination has a great impact to ultimate accuracy of vision measuring system. This paperderived firstly illumination transfer function in vision measuring system, then analyzed critical factors for illumi-nation design such as intensity, stability and uniformity, finally designed ring type cold illumination that can au-tomatic adjust intensity of light. The illumination orders a necessary material condition for vision measuring sys-tem.更多还原
