Pile measurement is an important means for developing production plans, ensuring accurate inventory management, and resource assessment in fields such as grain storage, coal mine management, and engineering construction.Therefore,The use of high-efficiency and high-precision 3D laser scanning technology to improve the accuracy of stack measurement is currently the development trend of stack measurement work.

Project Background

Recently, at the invitation of a client from a certain company, technical personnel from Shenzhen Yingfeiming Technology Co., Ltd. carriedThe T100 handheld 3D laser scanner (hereinafter referred to as T100) was sent to a certain location in Henan Province for coal pile scanning and measurement testing. The measurement volume error was less than 1%, meeting the customer's measurement requirements.

Pain point analysis

The pile environment is relatively complex, and the slope of the pile surface varies. Traditional measurements often cannot reflect the most realistic shape of the pile, and there are significant errors in data accuracy. Moreover, it is not suitable for managing large pile areas, which is time-consuming and labor-intensive. Traditional measurements cannot meet the requirements.

Implementation Plan

The T100 3D laser scanning mobile measurement system has the characteristics of real-time, accuracy, simplicity, and efficiency. Operators can start one click scanning operations with their hands. The mobile scanning method, combined with a powerful mapping system, greatly improves operational efficiency and meets inventory needs.

route planning

Before scanning, it is necessary to explore the on-site environment in advance and customize the scanning in advanceRoute to avoid repetitive scanning tasks.The collection route this time adopts a serpentine detour, and the interval between the paths does not exceed20To ensure that the collected point cloud is clearer and denser, and to avoid missing data. At the same time, the starting and ending points of the collected route coincide, making it easier for operators to correct and optimize point cloud layering during post-processing.

Pile point clouddata collection

Measurement personnel scan according to the pre planned scanning route, and during the scanning process, they can view the collection path, relative position, laser point cloud effect, as well as the situation of wrong or missed sampling in real time through their mobile phones, to prevent inconvenience and cost increase caused by multiple supplementary sampling.
