Abstract

<p> In our country, the utilization of ICT is promoted toward streamlining and labor saving in the investigation of the traffic volume of automobiles. In particular, investigation methods using moving images are drawing attention and various methods have been proposed. Now, the counting of a spot traffic volume has been realized but the flow investigation of vehicles between points has not been realized. Therefore, by adding a technology to identify the same vehicle to the existing technology, the investigation of the flow of vehicles between points becomes possible and this contributes to the sophistication of the investigation. Accordingly, this research created a method to identify the same vehicle by recognizing a series of designated numbers on license plates from moving images for a traffic volume investigation shot with more than one wearable camera. In the experiment, the created method was applied to moving images shot between two points to verify whether the same vehicle could be identified. As a result, the possibility was clarified that the same vehicle could be identified, which could not be measured with existing technology.</p>
