LiDAR-based Measurement System for Truck Bulk Cargo Volume

LiDAR-based measurement principle introduction:

LiDAR-based Measurement System uses high-definition solid-state video LiDAR to measure the empty truck body and loaded truck body, to obtain 3D imaging of the surface of the empty truck and the surface of the loaded truck with cargo.

Through the camera image data, the artificial intelligence (AI) method is used to confirm the loading status of the truck, and the picture is saved as the post-verification information and voucher.  By 3D fitting of the space coordinates before and after cargo loading, calculate the volume with the surface of the empty truck body and fully-loaded truck body to obtain the total volume of the loaded cargo. The 3D image point cloud, surface state, and 3D space volume state are all preserved as following confirmation and proof. The LiDAR-based measurement time is about 3 seconds.

Please see the following schematic diagram：

Diagram 1 – Scanning of empty truck (to obtain internal measurement data of the empty truck body)

Diagram 2 – Scanning of fully-loaded truck (to obtain the measurement data of the cargo surface)

Calculation method: by comparing the 3D plan view of empty truck body and fully-loaded truck body, generate 3D surface data from 3D cargo surface. Through the computer digital integration method, accurately calculate the volume of the cargo loaded in the truck. For the cargo > 5 cubic meters, the accuracy can reach over 95%.

A set of LiDAR-based measurement system for cargo volume includes the following parts：

1. Ground support

2. Neuvition high-resolution solid-state LiDAR

3. An image processing host computer 

4. A set of software algorithms for LiDAR vehicle volume calculation

5. Management platform software interface (API)

In the case of separate lanes for entry and exit, two systems are required.
