Identifying license plate information from images for several hundred vehicles per day
MissionA certain manufacturer of bridges and steel structures operates a number of factories on an extensive site in Wakayama Prefecture, working on multiple manufacturing projects simultaneously and in parallel to create structures for bridges and large buildings. Up to several hundred large vehicles and employee vehicles enter and leave these factories every day, and for safety reasons, it was necessary to reliably record the license plate, company and department of each of these vehicles. In addition, all vehicles entering or leaving the site were requested to stop at the security post, where the persons in charge were required to quickly note and record a detailed description of each vehicle as it entered or exited.
SolutionThe system that has now been deployed not only records the license plate information of vehicles entering and leaving the site by photographing their license plates using network cameras and analyzing the images obtained, but can also decide instantly whether the vehicle has already been registered or not. Another system was installed at the same time to monitor and record the major roadways within the factory site. Because the site is mainly outdoors, the camera chosen was AXIS P1365-E Mk II, rated to IP66 for resistance to water and dust. Footage taken by the AXIS P1365-E Mk II installed at the vehicle gate is recorded on AXIS S Series equipment locally, and is also forwarded to a server for identification of license plate information. This license plate information is then compared to the company’s vehicle database. If this comparison confirms that the vehicle has already been registered, the indicator in the security post turns green. For vehicles that have not yet been registered, the light turns red.
ResultPreviously, the license plate information of vehicles entering and leaving the factories was recorded manually, but the deployment of this solution has made it possible to carry out the process quickly and automatically.
