How to Display Reversing Trajectory in Rearview Camera?

[MalachiFitz]

Methods to display reversing trajectory in rearview camera: 1. Meaning of reversing trajectory lines. Red arc: Represents the trajectory line of the rear wheels when reversing with the steering wheel fully turned. Yellow line: Considered as a deceleration line, the position at the bottom of this line is 60 cm from the rear of the car, and you can continue reversing at a reduced speed. Green line: Represents the actual trajectory line of the rear wheels when reversing in the current state. 2. Judgment of line colors and distance in rearview camera. Green line: The distance between the obstacle and the rear of the car is large, and reversing is allowed. Indication: Safe distance. Yellow line: The distance from the rear of the car is 60 cm. Indication: Gradually pay attention to the distance. Red line: The distance from the rear of the car is 30 cm. When the car reaches near this line, the parking space is just right, and no further reversing is allowed. Indication: Warning line. If all lines are blue, the meaning is basically the same as above, with the line closest to the rear being the warning line, indicating to stop reversing. The slightly curved object in the image is the rear bumper of the car.
