There are three modes for screen switching: normal screen, screen after perspective transformation, and screen after normalization with processing markings.
After entering the autopilot interface, the servo gimbal will move to the default position. Note that the position shown in the blue box is the front position of the vehicle body. The bottom blue line cannot be too far from the front frame of the vehicle or on the vehicle body, otherwise the autopilot will not be able to patrol the line. If the deviation is too large, the gimbal direction can be controlled to the appropriate position, and then the autopilot switch can be turned on.

App remote control may fail

The APP screen can be seen, but the car cannot be controlled because the control process has been terminated by the mobile phone. Restart the APP and reconnect to the car.
The sensor data of the APP is not updated in real time because the phone sleeps and the process of receiving the sensor is terminated, resulting in the termination of the thread of sending data in the large program. In this case, you need to restart the app and the car.
