Vehicle outline and wheel base automatic measuring system and measuring algorithm

The invention discloses a vehicle outline and wheel base automatic measuring system and a measuring algorithm. The vehicle outline and wheel base automatic measuring system comprises three distance measuring units, an outline measurement control unit, a wheel base measurement control unit, an evidence collection unit, a comprehensive data processing unit and a measurement channel. The distance measuring units, the outline measurement control unit, the wheel base measurement control unit and the evidence collection unit are arranged on the measurement channel. The three distance measuring units are the first distance measuring unit B1, the second distance measuring unit B2 and the third distance measuring unit B3 respectively. The outline measurement control unit is connected with the three distance measuring units respectively. The wheel base measurement control unit is connected with the first distance measuring unit B1. The distance measuring units are connected with the comprehensive data processing unit. The evidence collection unit is used for monitoring and recording the real-time condition of running of a detected vehicle. The vehicle outline and wheel base automatic measuring system can automatically measure vehicle outline data including the length, width and height of the vehicle and wheel base data of the vehicle, ensure the measuring accuracy and improve the measuring efficiency.
