Tips: How to automatically calibrate 360 dash cam with checkerboard map?

1. Lay out the checkerboard map
   • For 360 dash cam 2D:
     The front and back checkerboard cloths are based on the rectangle formed by measuring tape, and put is to the outside. The center line of the checkerboard cloth is required to be same with the center line of the rectangle.
     The left and right checkerboard cloths are based on the rectangular box formed by measuring tape, and also put it to the outside. The center line is aligned with the camera of the left and right rearview mirror.
     Read L (rectangle length), W (rectangle width), D (offset position), and record, D1=D2=D. D1/D2 is the distance between front cloth and left/right cloth.
   • For 360 dash cam 3D:
     The map consists of two checkerboard cloths, a large U-shaped cloth in front of the car, and a small square cloth in the back of the car. Lay the two pieces of cloth smoothly in order. Note that the distance between the tail of the front cloth and the back cloth should be selected according to the length of the car body. The distance on the indicator line is 0.8m, 1m, 1.2m, 1.4m, 1.6m, 1.8m, etc.
2. Adjust the camera position
   
   • For the front and rear cameras, adjust the angle of the camera until you see that there is no gap between the image and the car body, and does not cover the black and white checkerboard intersection.
   • For the left and right cameras, adjust the angle of the camera until you see part of the car body. At the same time, A and B should be the same as possible. That is, the checkerboards seen from the front and rear of the car look similar. Try to avoid serious deformation in one place.
   • The distance between the calibration cloth on the left and right sides and the car body should be the same as possible.
3. Calibration
   Enter the 360 ​​dash cam setting menu and select the calibration option. According to the actual distance between the back cloth and the front cloth, select the corresponding distance option. Then choose "starting calibration" and the 360 degree panoramic system enters the 4 in 1 monitoring interface. Press the remote control again, and the system will start automatic calibration. About 10-20 seconds, the interface will prompt whether the calibration is successful.
   • If the calibration is successful, the system will automatically restart after 3 seconds.
   • If the calibration fails, the system will prompt which camera failed the calibration.
