基于背景差法和帧间差法的运动目标检测方法

New moving target detection method based on background differencing and coterminous frames differencing

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。本文在介绍了各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。

Lighting variation is one of the primary factors to influence the nighttime monitoring system. Background updating is the effective method to overcome the lighting effects. A new motion detection and background updating method was developed based on the background ditterencing and coterminous frame differencing. Experiments show that it is roblust under lighting variations, and the warning system stability is improved.
