To provide a traffic congestion detection device, a traffic congestion detection system, and a traffic congestion detection method capable of improving the tracking of changes in photographing results.SOLUTION: A determination window is a pixel area in a video in which the traffic congestion of a moving vehicle is detected. A traffic congestion detection device includes: a determination window generation unit 22B that generates a determination window for a new video from the video using a learner that has been trained to generate a determination window from time-series data indicating a position of a vehicle identified in the video; and a traffic congestion estimation unit 23 that estimates the traffic congestion of vehicles in the determination window generated by the determination window generation unit 22B by calculating the density of the vehicles in the determination window generated by the determination window generation unit 22B.SELECTED DRAWING: Figure 4
【課題】撮影結果の変化に対する追従性を向上可能とした渋滞検知装置、渋滞検知システム、および、渋滞検知方法を提供する。【解決手段】映像のなかで移動体の渋滞を検知するピクセル領域が判定窓である。映像のなかで特定された車両の位置を示す時系列データから判定窓を生成するように学習した学習器を用いて新たな映像から当該映像の判定窓を生成する判定窓生成部22Bと、判定窓生成部22Bが生成した判定窓における車両の密度を算出して判定窓生成部22Bが生成した判定窓での車両の渋滞を推定する渋滞推定部23とを備える。【選択図】図4
