The invention provides an optimization system and an optimization method for measuring a vehicle front wheel turning angle and a zero error based on a non-contact angle sensor. The device is mainly used for measuring the front wheel turning angle of a vehicle in an unmanned environment and comprises a sensor unit and a control unit. The sensor unit comprises two non-contact angle sensors, one non-contact angle sensor is mounted at a front wheel of the vehicle, and the other non-contact angle sensor is mounted in the center of a vehicle body in a welding and threaded fastening manner; the control unit is composed of an industrial control board and a serial port screen, the industrial control board is responsible for reading sensor data, obtaining the theoretical front wheel turning angle of front wheels of the vehicle through operation, and meanwhile operating an optimization method to reduce the influence of zero errors on the path tracking effect; and the serial port screen is used for displaying data of eac
