StarScan electric power inspection "repair wires" program
2021-08-26 10:30:40
With the rapid development of UAVs and lidars, the use of UAVs equipped with lidars for power inspections has become a wide range of operations.
Focus Point
Under extremely special environmental and terrain conditions, the power wires scanned by the laser may be missing or disconnected.
Old Solution
The UAV-borne lidar re-flights for power wires supplementation,
resulting in waste of manpower and material resources, high operating costs and operational complexity.
Efficient New Solution
Hand-held StarScan equipment for power wires supplementary mining is simple to operate and can be completed by one person.
Equipment introduction
"StarScan" handheld 3D laser scanner
"StarScan" is the first handheld lidar device independently developed by Surestar. Our handheld 3D laser scanner weighs only 1.3kg. It can be started with one button, easy to learn, easy to use, and highly integrated, allowing easy access to almost all Job site.
"StarScan" has a high-precision SLAM algorithm, and has the advantages of small size, light weight, high accuracy, and convenient use. Different from the traditional way of carrying lidar (airborne, vehicle-mounted), StarScan is ergonomically designed, and it is comfortable and easy to hold. It can be operated by only one person.
"StarScan" can realize single-person operation, namely walk and scan, and complete. For example, in the power inspection operation, it can simply and quickly complete the "leakage repair" work of the leaked power corridor, which has become the best for airborne lidar power inspection The partner, compared to re-flying to "repair wires", greatly reduces the cost of investment and greatly improves the efficiency of the power inspection project.

Operating Procedures
Applications
Data Collection
Use the handheld laser radar StarScan to collect point cloud data in the survey area, and if it is found that the power wire is missing, the missing power wires can be filled with post-splicing software.
After collecting the point cloud information of power wires, towers and ground objects within the measurement area, it is filtered through the supporting power software to realize the classification and extraction of the power corridor point cloud and the surrounding environment point cloud, and then automatically detect or calculate the power corridor surroundings "Dangerous" point information, crossover information, maximum working condition simulation information, etc. Provide intuitive diagrams, texts and other forms of power inspection reports for power operation and maintenance units to realize production services.
Data Solution
The raw data collected by StarScan uses StarSolve software to calculate the point cloud, without parameter configuration, and one-click output point cloud.

Supplementary data
Point Cloud Stitching
The missing power wires are spliced through the later software, and the feature points between the two point clouds are selected to match the point clouds, to achieve the point cloud fusion splicing effect, and efficiently solve the problem of missing power wires.
Select 3 pairs of feature points for point cloud stitching

Summarize
From the previous manual inspections to the current UAV-borne lidar inspections, the work efficiency of the power industry has been greatly improved.
In the case of small-scale power operations or power supplementary testing, the use of UAV-borne lidar operations invisibly increases operating costs and waste of manpower. At this time, the advantages of the handheld lidar "StarScan" are reflected. It weighs only 1.3kg, is one-key start, easy to learn, easy to use, highly integrated, and can easily enter almost all work sites. It is simple to operate, and one person can do it. Almost unaffected by the weather environment, greatly reducing the cost of repeated operations!
At present, vehicle-mounted and airborne lidars are developing rapidly, but there are also scenes that cannot be realized, such as tunnels, indoors and other scenes. The emergence of handheld lidars perfectly solves this problem. "StarScan" can work with UAVs as well as with vehicle-mounted lidar, which is an effect of 1+1>2. Handheld lidar is the most flexible "arm"!（www.isurestar.net）
