To provide a traveling direction determination device that does not erroneously determine a traveling direction.SOLUTION: A traveling direction determination device comprises: a vehicle tracking function in which an arithmetic processing unit tracks a vehicle V moving in a bird's-eye view image F as a frame portion W with respect to a traffic road of an intersection K of the bird's-eye view image F input from an imaging unit; and a determination function for determining a traveling direction of the vehicle V by that an inflow line Li is set on an upstream side where the vehicle V in the bird's-eye view image F flows into the intersection K, an outflow line Lo is respectively set on a downstream side of traveling directions of a straight, a right turn, and a left turn where the vehicle V flows out from the intersection K, a center point of the frame portion W is set as a determination point H, and after the determination point H passes the inflow line Li, the outflow line Lo through which the vehicle first passes is detected.SELECTED DRAWING: Figure 4

    【課題】進行方向を誤判定することのない進行方向判定装置を提供する。【解決手段】撮像部から入力される俯瞰画像Fの交差点Kの通行路に対して、演算処理部が俯瞰画像F内で移動する車両Vを枠部Wとして追尾する車両追尾機能と、俯瞰画像F内の車両Vの交差点Kに流入する上流側に流入ラインLiが設定され、交差点Kから車両Vが流出する直進、右折、左折の進行方向の下流側にそれぞれ流出ラインLoが設定され、枠部Wの中心点を判定点Hとし、この判定点Hが流入ラインLiを通過した後に、最初に通過した流出ラインLoを検出することで、車両Vの進行方向を判定する判定機能を備えている。【選択図】図4
