A background model extraction device, a traffic congestion detection method and device, in which the background model extraction device includes: a first detection unit for detecting the moving speed of the current image predetermined area; a first update unit for using the image pixels which are not moving in the predetermined area as background pixels when the moving speed exceeds the first threshold value. Update the background model. As a result, it has robustness under different video conditions, and can improve the accuracy of foreground image detection, avoiding the problem of low accuracy of foreground image detection caused by foreground integration and foreground locking.
