为了解决成像型激光探测系统外场试验常易出现的太阳光虚警问题,提出了一种通过提高图像帧频抑制太阳光虚警的方法,讨论了该方法的适用性,给出了最佳频帧的选取办法,并在外场太阳直射条件下进行了实地验证。结果表明,该方法可减小探测系统对背景的积分时间,有助于缩小太阳周围虚警杂光的成像范围,有利于抑制虚警,为成像型激光探测系统后续的研制和测试提供了有益的参考。
In order to solve the problem of false alarm of sunlight in field test of imaging laser detection system, a method of suppressing false alarm of sunlight by increasing the frame rate of image is proposed. The applicability of this method is discussed and the optimal frequency Frame selection method, and in the field under the direct sunlight conditions were verified. The results show that this method can reduce the integration time of the detection system to the background and help reduce the imaging range of false alarm light around the sun, which is good for suppressing false alarms and providing benefits for the subsequent development and testing of imaging laser detection system The reference.
