红外摄像机通过主动补光提高了夜间成像效果,在安防监控领域得到广泛的应用,通过优化照明光源设计、图像传感器及处理系统设计均会改善其夜间成像效果。通过理论分析和实验方法,阐述了摄像机照明光源与夜间成像效果之间的关系。实验结果显示,通过合理的选择光源输出光功率、发散角和配光布局,使成像区域具有足够的亮度和照度均匀性,能够有效的改善夜间成像效果,降低摄像机功耗。
The infrared camera improves the nighttime imaging effect through active fill light and is widely used in security monitoring. By optimizing the illumination light source design, the image sensor and the processing system design will improve the nighttime imaging effect. Through theoretical analysis and experimental methods, the relationship between camera illumination light source and nighttime imaging effect is expounded. The experimental results show that by reasonably selecting the light output power, the divergence angle and the light distribution layout, the imaging area has sufficient brightness and illumination uniformity, which can effectively improve the nighttime imaging effect and reduce the camera power consumption.
