PROBLEM TO BE SOLVED: To reduce a processing load necessary for reading.SOLUTION: An installation body is erected in the upper space of a running traffic lane so as to traverse the running traffic lane on which a vehicle carrying a license plate travels. Line sensor imaging means having a line sensor in which imaging devices are arranged in a line is installed such that the arrangement direction of the imaging devices traverses the running traffic lane and the vehicle traveling along the running traffic lane can be imaged from obliquely upward of the vehicle. A license plate is read on the basis of the image of the license plate included in a two-dimensional image generated from time series line sensor images imaged by the line sensor imaging means.SELECTED DRAWING: Figure 1

    【課題】読み取りに要する処理負荷を低減すること。【解決手段】ナンバープレートが装着された車輌が走行する走行車線を横断するように該走行車線の上方空間に架設された架設体に、撮像素子が1列状に配列されたラインセンサを有し、該撮像素子の配列方向が前記走行車線を横断する方向となるとともに、前記走行車線を走行する車輌を該車輌の斜め上方から撮像可能となるようにラインセンサ撮像手段を設置し、ラインセンサ撮像手段にて撮像された時系列のラインセンサ画像から生成される2次元画像に含まれるナンバープレートの画像にもとづいて、ナンバープレートを読み取る。【選択図】図1
