Not precise depth values

We have enabled the depth camera on the simulator, but the depth values are given as integer and are not precise. For example, in [this](https://imgur.com/a/dEkQgQA) image, the yellow cone on the right is given a depth of "5", the blue one is "6" and the yellow one in the distance is "15". This seems wrong as the cones are very close to the car's wheel and it's strange to see a depth of 5(meters?) from the camera.

The RGB image that I sent corresponds to the depth one, we set the two cameras to be in the same position in the settings.json
