摘要
为了研究日盲型紫外探测中的目标定位,设计了1套紫外探测实验系统。提出了1种基于目标图像的定位算法,通过确定目标在像平面上的位置,计算目标方位角。对系统及算法进行了理论分析和实验验证。以氘灯为目标的紫外光源,探测系统在30m处取得了0.5°的方位角测量精度。结果表明,该定位算法是可行的。这一结果对进一步开展远距离实验、完善系统是有帮助的。
A set of ultraviolet detecting experiment system was designed to study the target location in solar blind ultraviolet detecting. A kind of location algorithm based on the target image was brought forward. Target azimuth was calculated by the location of target on the image plane. The detecting system and algorithm were analyzed and validated in experiment. With 30m between the deuterium lamp and the detecting system,the measure precision of target azimuth angle can reached 0.5^.. The result shows that the location algorithm is feasible. The result helps to carry out farther distance experiment and improve the system.
