In the process of comprehensively deepening the digital reform of buildings, the three-dimensional laser scanning technology has been widely used in various types of buildings with its fast, efficient and comprehensive three-dimensional spatial information capture capabilities and intuitive visualization, computing and analysis of intelligent data advantages, including modern real estate projects, urban houses, rural cadastrals, building facades, ancient buildings, etc.

The three-dimensional data obtained by 3D laser scanning technology is more malleable and operable than traditional paper data recording forms.

GoSLAM building 3D scanning solution

Project overview

This period measurement plan, we went to the building park to see how GoSLAM handheld 3D scanner can efficiently obtain building color point cloud data with breakthrough synchronous positioning technology.

▲Building 3D scanning site

Technical advantages

GoSLAM mobile measurement system can obtain three-dimensional spatial information of complex site environments and spatial targets, quickly reconstruct the three-dimensional model data of the target, and objectively reflect the true morphological characteristics of things. Its specific advantages are:

▲Building 3D scanning site

• single-person handheld device, which can realize continuous collection of building point cloud data while moving.
• 's unique rotary measuring head scan rate is as high as 320,000 points per second, making data acquisition more efficient.
• 360°×285° Extra large field of view angle, all-round scanning, complete data acquisition and no omissions.
• mobile APP replaces traditional touch screens and browses point cloud data in real time.
• does not require GNSS positioning such as GPS, and can shuttle freely and have strong environmental adaptability. During the
• scanning process, perform SLAM calculation in real time, and export it and use it.
• is developed based on multi-platform and can be equipped with handheld, backpack, car, and drone.

Solution

Before scanning, first plan the route and adopt wraparound data collection for the buildings to ensure that all buildings in the test area have passed to ensure the integrity of point cloud data.

▲Building three-dimensional scanning site

After turning on the scanning with one click, just walk at normal pace and match it with a color module, the device will automatically collect real color data of surrounding buildings while moving. Using the mobile APP, you can also browse point cloud data in real time and perform operations such as zooming, dragging, and rotating.

▲Open three-dimensional scanning with one click

scan ends, and the data can be exported directly from the scanner to the point cloud processing software, because the device provides real-time registration function, and exporting the data is the whole, and no point cloud registration is required.

Summary of this issue

Use lidar and SLAM algorithms to realize integrated measurement of multi-scene buildings. The non-contact data acquisition method can collect data without touching the object table, and is widely used in forestry, underground space, mineways, street facades, stack volume measurement and other fields.
