[Highway Techno Fair 2021] 3D Digital Road Data Measurement Officer "3D DHDV" - Japan Road Corporation

Hello. It is a Japanese road.
We introduce our three-dimensional digital road data measuring car.

Laser and laser in units mounted behind

Camera and cameras are equipped with various devices and cameras.
There are two left and right, and the road surface of the road width four meters is

High precision, three-dimensional digitization.

What is said to be a general road surface measurement car is the main photo,

I do not know uneven information well.
In the case of this car, the unevenness can be taken as three-dimensional data,

After returning from the site to the office,

The situation of this site,
It can be grasped exactly as 3D.

I think you can see if you actually look at it.

We introduce 3D data introduced earlier, on the PC screen.

Here is the situation where the left side road was taken with the camera.

This is taken with a certain concrete pavement.
Because it is a camera, it is partially dirty,

I only know about that, but

This will happen if this is 3D.
There is unevenness in the place where

I think that it can be seen clearly that the stone is flying.
This is the biggest feature of this car.

There is another feature.
The planarity and IRI will be important when checking the road, but

This car has a sensor on both left and right, so

The flatness of the left and right of the tire can be measured.

Perhaps it is a machine that seems to be this only in Japan.
Because there is a characteristic of the above, everyone is for road management etc.

I think that it can be helpful. Thank you very much.
