With the in-depth development of electric power inspection,the way of inspection is gradually becoming automatic and intelligent.

　　As a new technical means,LiDAR has the technical characteristics of active remote sensing,high point frequency,high precision and high efficiency.It has been applied more and more in UHV channel inspection,fine inspection,tower completion acceptance,substation field modeling and other scenes,bringing revolutionary changes to the safety detection of power operation and maintenance and power transmission.

　　Airborne LiDAR mode is generally used in channel inspection and tower point cloud data acquisition.However,UAVs are usually prohibited or restricted from flying near airports,densely populated urban areas and classified areas.

　　Using terrestrial 3D laser scanner can effectively avoid the above problems.

　　01.Solution

　　HD TLS360 mini portable 3D laser scanner,an artifact of Hi-Cloud for single operator,takes only 1 minute to complete acquisition in one station,saving time and labor.It has been well used in power tower scanning.

　　List of equipment

　　Equipment advantage:

　　Lightweight and compact,the whole machine is easy to carry;

　　It can operate the measurement without accurate leveling;

　　One key operation,simple and convenient wireless operation;

　　Cost-effective and the application scenario is unlimited.

　　02.Workflow

　　Firstly,the station is selected at the operation site.Generally,the area with good intervisibility conditions and 10-20m away from the tower is selected to set stations.

　　Then,set the tripod,fix the TLS360 on the tripod,connect the mobile phone to the device WiFi after startup,and set the acquisition parameters.

　　TLS360 scanning station

　　Since TLS360 has an tilt compensation of±5°,automatic measurement can be started without leveling.

　　One click automatic acquisition can complete the data scanning of one station within 1 minute at the fastest,or set different scanning time according to the requirements of point cloud density.

TLS360 data acquisition

　　After data collection in one station,the scanner can be directly moved to the next station to ensure that the two stations have overlapping areas.TLS360 is lightweight and easy to carry,and one individual person can complete all operations.

　　03.Achievement

　　The following is part of the results of TLS360 power tower data acquisition,which can be seen:

　　The overall structure of the tower is very complete,tower head,cross arm,angle steel structure is clear;Insulator structure is relatively complete;No broken power lines;The tower base data is complete.

Over all data results

　　Tower pole and power line data results

　　Insulator data results

　　Tower base data result

　　With the continuous iterative upgrading,performance improvement and further optimization of data processing of TLS360,it will be more widely used in power transmission,operation and maintenance security and other scenarios.
