摘要
影响夜间监视系统稳定性的主要因素之一是光线的变化,背景更新方法则是克服光线影响的有效方法。在研究了多种现有方法的基础上,提出了一种基于背景差法和帧间差法相结合的运动目标检测和自适应背景更新方法。实验证明这种方法能够很好地克服光线的影响,提高报警系统的稳定性。
One of primary infecting complication of the stability for monitor system is due to lighting variations. Background updating is the effective method to conquer the infection of lighting. We develop a new method of motion detection and background updating based on the researches for existing methods. Experiments proved that this method is the one to overcome effectiveness well in the lighting variations and enhances the stability of warning system.
