To provide a travel direction estimation device for easily estimating a travel direction of a vehicle from a captured image.SOLUTION: A travel direction estimation device includes a tractor detection part for detecting a tractor towing a trailer of a vehicle from a captured image captured by an imaging device. The travel direction estimation device includes a trailer ID estimation part for estimating a trailer ID for identifying the trailer from a character string detected from the captured image. The travel direction estimation device includes a travel direction estimation part for estimating a travel direction of the vehicle based on a physical relation between the tractor and the trailer ID in the captured image.SELECTED DRAWING: Figure 13

    【課題】撮像画像から容易に車両の進行方向を推定する。【解決手段】進行方向推定装置は、撮像デバイスによって撮像された撮像画像から車両のトレイラを牽引するトラクタを検出するトラクタ検出部を備える。進行方向推定装置は、撮像画像から検出された文字列の中からトレイラを識別するトレイラIDを推定するトレイラID推定部を備える。進行方向推定装置は、撮像画像内におけるトラクタとトレイラIDとの位置関係に基づき車両の進行方向を推定する進行方向推定部と、を備える。【選択図】図13
