How to Judge the Distance Between the Right Side of the Car and Obstacles?

[HaleyLee]

Methods to judge the distance between the right side of the car and obstacles: 1. Height: Mainly estimated based on the comparison of the blocked height. 2. Distance from the roadside: Determine the position of the roadside in the windshield (the left wheel is 10-15cm to the right from the left pillar of the windshield; the right wheel is 5-10cm to the left from the center line of the windshield); the distance from the roadside can be seen from the rearview mirror. 3. Right wheel position: Determine the position of the right wheel (middle of the front of the car or right wiper): relative to the ground at one-third of the right side of the front cover. 4. Three-point alignment: When the eyes, the front edge of the car hood, and the point where the obstacle touches the ground are aligned, the obstacle is approximately 1.5 to 2 meters away from the front of the car.
