Revolutionizing Stockpile Measurement: Lixel L1's Innovative Approach for Precise and Efficient Surveys

Case Studies2023.12.274 min read

Lixel L1, with its convenient data collection, efficient processing, and accurate precision, has found extensive applications in various scenarios.

As an essential method for production plan, inventorying material stocks, and assessing agricultural yields in industries such as engineering, mining, and agriculture, stockpiles measurement plays a more and more crucial role.

Collaborating with XGRIDS'S partners, Lixel L1, with its convenient data collection, efficient processing, and accurate precision, has found extensive applications in scenarios involving stockpiles measurement across engineering, mining, and agriculture sectors.

Existing Challenges

Visual Estimation: Prone to significant errors and subjectivity.
In-Out Records: Prone to omissions, leading to cumulative errors in frequent operations.
Stationary Scanner Measurements: Inefficient and incapable of meeting real-time data requirements.
Fixed Monitoring Devices: Immobile, requiring a large quantity, resulting in significant overall cost.
Weighing Measurements: Time-consuming, labor-intensive, low applicability, bad accura

cy and high costLixel L1 Operation Workflow Example

(Taking an indoor material stockpile heap as an example)

Part 1: Plan Route for Scanning

Planned closed-loop route for scanning a stockpile heap with the Lixel L1

Confirm start and end points of the scanning and scan through a closed-loop covering the entire stockpile heap with Lixel L1's laser point cloud.

Part 2: Scan With the Lixel L1

Operator scanning a material stockpile on site with the Lixel L1

Utilize Lixel L1 for scanning. With a single operation lasting up to 90 minutes, it satisfies the majority of field work scenarios. No need for station changes or post-processing alignment—providing a smooth and reliable workflow. During the scan, real-time preview of point cloud results on a mobile device matches the final exported results.

Paired with the point cloud processing software, measure and calculate 3D heap point cloud data, outputting comprehensive result reports.

Lixel L1, employing a fusion of multi-source data and SLAM technology, quickly obtains the length, width, and volume of the target stockpile heap. It generates 3D model data, offering measurability and visibility. The efficiency is more than 10 times that of traditional methods. Lixel L1 allows for on-the-spot measurements, saving field working time, significantly improving lab working and processing efficiency, and substantially reducing economic and time costs per project. The integrated design of its body is easy to grip for single-handed operation and mobile scan. Additionally, it supports backpack and various mounts operations, meeting various work requirements in different scenarios and measurement ranges.
