Vehicle-mounted camera calibration system and method based on video injection

The invention provides a vehicle-mounted camera calibration system and method based on video injection. The system comprises a scene generation unit, a first video injection unit, a foresight camera controller, a second video injection unit, a visual box, an upper computer monitoring unit, an Ethernet converter and a controller to be calibrated. The scene generation unit is provided with two output branches, one output branch is a first video injection unit and a foresight camera controller which are connected in sequence, and the other output branch is a second video injection unit and a visual box which are connected in sequence; the foresight camera controller is in wireless connection with the controller to be calibrated through a vehicle-mounted Ethernet, and the visual box is further electrically connected with the controller to be calibrated; the controller to be calibrated and the visual box are both in wireless connection with the Ethernet converter through the vehicle-mounted Ethernet, and the outpu
