To provide a device and a method for detecting a vehicle entering a restricted area that is easy to install and can accurately detect vehicles over a wide area, while reducing the complexity of the device configuration compared to conventional devices.SOLUTION: A vehicle detection device includes: an imaging camera for acquiring image data; an image analysis unit that analyzes the image data to detect a vehicle entering a restricted area; and an alarm transmitter that gives an alarm to notify workers when the vehicle entering the restricted area is detected by the image analysis unit. The image analysis unit includes: a boundary detection unit that detects a boundary of the restricted area by detecting rows of the vehicle guidance bodies lined up on the road; a regulatory area side detection unit that detects which sides of the boundary of the restricted area detected by the boundary detection unit is the regulatory area side; and a vehicle entry monitoring unit that monitors whether or not the vehicle crosses the boundary of the restricted area and enters the regulatory area side.SELECTED DRAWING: Figure 1
【課題】従来に比べて装置構成が複雑化することを抑制することができるとともに、設置が容易で広範囲に亘り正確に進入車両の検出を行うことのできる規制領域内への進入車両検出装置及び検出方法を提供する。【解決手段】画像データを取得するための撮像カメラと、画像データを解析して規制領域内への進入車両を検出する画像解析部と、画像解析部にて規制領域内への進入車両が検出された場合、警報を発して作業員に知らせる警報発信部とを具備し、画像解析部は、道路上に並べられた前記車両誘導体の列を検出して規制領域の境界線を検出する境界線検出部と、境界線検出部にて検出された規制領域の境界線のどちらが規制領域側であるかを検出する規制領域側検出部と、規制領域の境界線を越えて規制領域側に進入する車両の有無を監視する進入車両監視部と、を有する。【選択図】図1
