Margin of Error Between Road Surface on Screen and Actual Road Surface

There might be some margin of error between the road surface appearing on the screen and the actual road surface. A margin of error in the perceived distance could lead to an accident, therefore be aware of the following conditions which can more easily produce errors in the perceived distance.

 

The vehicle tilts due to weight of passengers and cargo.

If the vehicle is tilted, obstructions picked up by a camera can appear farther or closer than the actual distance from the vehicle.

There is a steep up or down grade in the road at the front or rear of the vehicle

If there is a steep up or down grade in the road at the front or rear of the vehicle, obstructions picked up by the camera can appear farther or closer than the actual distance from the vehicle.

Front camera

  1. Appears further than actual distance

  2. Distance of obstruction being viewed on screen

  3. Actual distance of obstruction from vehicle

  4. Actual obstruction

  5. Obstruction appearing on screen

  6. Appears closer than actual distance

Side camera

  1. Appears further than actual distance

  2. Distance of obstruction being viewed on screen

  3. Actual distance of obstruction from vehicle

  4. Actual obstruction

  5. Obstruction appearing on screen

  6. Appears closer than actual distance

Rear camera

  1. Appears further than actual distance

  2. Distance of obstruction being viewed on screen

  3. Actual distance of obstruction from vehicle

  4. Obstruction appearing on screen

  5. Actual obstruction

  6. Appears closer than actual distance

 

If the vehicle is on a slope, obstructions taken by the camera can appear farther or closer than the actual distance from the vehicle.

Three-dimensional object at vehicle front or rear

Because the vehicle front end guide lines (side camera) or the distance guide lines (rear camera) are displayed based on a flat surface, the distance to the three-dimensional object displayed on the screen is different from the actual distance.

Side camera

  1. (Screen display)

  2. (Actual condition)

Rear camera

  1. (Screen display)

  2. (Actual condition)

  3. Sensed distance on screen A>B>C

  4. Actual distance B>C=A
