As-built survey with 3D LiDAR handheld HiSLAM 10cm accuracy and 120m range

As-built survey is an important project in urban construction and development. After the building construction is completed, the developer shall provide a copy of completion acceptance data to the urban planning management department to ensure that the completion acceptance indicators meet the original planning and design requirements. The main contents of the completion acceptance of the building include the peripheral side length of the building, the plane coordinate position of the peripheral corner of the first floor of the building, the ± 0.00 elevation of the building, the total height of the building and the positional relationship between the building and the surrounding existing roads. As there are many items to be measured in the as-built survey, the traditional total station, RTK and other measuring instruments have low efficiency and poor adaptability to the environment, which can not meet the efficiency requirements of large-scale as-built survey.

HiSLAM 3D laser scanner has the advantages of high scanning efficiency, large amount of data information and high precision, and can realistically simulate any complex environment, which fully reflects the practicability and scientificity of the product. Based on HiSLAM, the 3D laser scanner can complete the point cloud scanning task of the whole scene in the moving process, and then carry out various measurement and drawing based on the point cloud data, so as to improve the overall speed and efficiency of as-built survey.

Features of HiSLAM

1. High accuracy: high point cloud density, high point recognition rate, high measurement accuracy

2. High intelligence: seamless integration of point cloud an panorama

3. Calibration free: calibration is independent of the carrier

4. Easy transportation: small size, light weight, convenient transportation

5. Multi carrier: suitable for handheld and backpack mode
