LiDAR "efficient" heap volume measurement, real stuff sharing!

2021-07-26 14:37:27


Volume measurement is a relatively common job in social production activities. For example, in infrastructure projects and highway construction, the volume of earth fill and excavation needs to be obtained, and in mine management projects, it is necessary to evaluate or count the reserves and mining volume.

In addition, in the port terminal where ore, coal and other goods are loaded and unloaded, the accumulated ore piles, coal piles and other goods also need to quickly and accurately obtain the volume.

In different industries, the measurement and calculation of volume have different requirements in terms of timeliness, accuracy and cost.

Technical process

Hardware solution

"StarScan" is a portable handheld LiDAR. The scanning speed of 320,000 points per second can collect more scene information and model the data. Combining LiDAR and synchronous positioning and mapping (SLAM) technology, StarScan It can be used freely in the narrow airwaves, and it can still achieve centimeter-level data accuracy without GPS signals.


"Surestar" has a high-precision SLAM algorithm, and has the advantages of small size, light weight, high precision, and convenient use. Different from the traditional Lidar carrying method (airborne, vehicle-mounted), Surestar is more ergonomic design, comfortable and easy to hold, and can be operated by one person. "Surestar" can realize single-person operation, that is, walk, scan, and complete!


Software solution

Point-clouds calculation: One-click calculation, automatic registration of original point clouds, and output standard format *.las point cloud data.

Point-clouds processing: project management, cropping, filtering, DEM production, volume calculation and volume report output.

Solution

Use "Surestar" to quickly and accurately obtain the three-dimensional model data of the target object, and combine the supporting software to output the target volume.

Route planning & data collection

In volume measurement, absolute coordinates are not required. The DEM of the detection target can be quickly and directly established based on the detection target point cloud, and the volume of the pile can be directly obtained by comparing the target DEM with the starting surface (reference surface).

In this case, a "closed loop" line scan method is used to scan around the target stack.


Technicians are collecting data

Point-cloud solution

There is no need for target orientation or GPS-assisted positioning. The collected raw data will be resolved and registered in StarSolve to directly obtain high-precision registered point cloud data.


According to the point cloud of the pile body and the ground surface model below the pile body, the grid method is used to quickly calculate the volume and output the report.



Summarize

In the case of volume measurement of material stack in a stone yard, the "Surestar" lidar product is used for data collection until the data is solved, and it only takes about 10 minutes to obtain the volume report.

"Surestar" is easy to operate: the system weighs only 1.3kg and adopts an ergonomic design, so a single person can easily perform collection tasks.

The battery life of "Surestar" is up to 1 hour and 30 minutes, and there is no pressure even in the pile volume scanning operation of larger scenes.

"Surestar" is easy to get started: the data calculation adopts the standard configuration software, the original data obtained can be downloaded through the network cable to complete the one-click calculation, and it can be used after the video tutorial.



The process of "Surestar" volume measurement of material stack solution data collection to processing and generating a pile volume report is fast, accurate, low personnel input, cost-effective, and has a wide range of applications. It can be applied to mine piles and earthwork in engineering infrastructure construction. Volume measurement operations for engineering and industrial pools, chemical tanks, etc.
