【摘要】 近光灯明暗截止线及拐点检测是汽车前照灯检测中极为重要的技术项目。本文依据热点、水平明暗截止线及倾斜明暗截止线三者之间的相对位置关系,提出了一种基于热点的自适应感兴趣区域定位算法,并对其进行了较为详细的阐述。最后,通过使用标准光源,从视觉和检测偏转角两个方面对算法进行验证。验证结果表明,本文的算法具有较好的鲁棒性、稳定性及实用性。更多还原

【Abstract】 Detection of the cut-off line and corner of low-beam is an important item in the examination of vehicle headlamps. This paper proposes an adaptive localization algorithm of the region of interest that is realized on the basis of the relationship among the hotspot, the horizontal cut-off line and the inclined cut-off line, and presents an analysis and discussion of the algorithm in detail. The algorithm is then examined from two aspects of the vision and deflection angle measurements, by using the standard low-beam source. The result shows that the proposed algorithm has good robustness, stability and possibility for practice.更多还原
