Overview: The Z-Lab LiDAR Mini LiDAR System SZT-R250 by South Surveying & Mapping Technology Co., Ltd. is a comprehensive solution for various surveying and mapping applications. It integrates advanced LiDAR technology with imaging sensors and UAV platforms to deliver high-precision data capture.
Specifications: The system features a RIEGL miniVUX-1UAV laser sensor with a maximum range of 250 meters and a field of view of 360°. It supports a measurement rate of up to 100,000 measurements per second with an accuracy of 5 cm at 50 meters for UAV applications. The imaging sensor is a 24.3 MP RGB camera, and the system operates within a temperature range of -10°C to 40°C.
Hardware Configuration: The SZT-R250 is equipped with a SPAN IMU-IGM-S1 POS system, offering gyro bias stability of 0.05° per hour and processed roll/pitch accuracy of 0.006°. The system's power consumption is 27 W, and it supports data storage on SDHC/SDXC cards up to 128 GB.
Software Solutions: The system includes Z-Lab LiDAR-ctrl, Z-Lab Pt-process, Z-Lab Mapper, and TerraSolid for processing and mapping. These tools facilitate point cloud browsing, rendering, cropping, and vectorized mapping, with capabilities for 3D viewing in Google Earth and direct measurements in panoramic views.
Applications: The SZT-R250 is suitable for a variety of applications, including topographic and cadastral surveys, traffic network development, forestry investigation, power transmission industry applications, disaster monitoring, and irrigation system development. It offers efficient data capture and high accuracy, making it ideal for challenging environments and complex terrains.
Performance Metrics: The system's performance varies with flight altitude and scanning speed, affecting point density and coverage area. For example, at a flight altitude of 50 meters and a scanning speed of 18 km/h, the point density is 38 points per square meter, covering 0.25 square kilometers per flight.
Operational Considerations: The document notes that complex terrains may reduce efficiency and recommends shifting the ground base station when the radio datalink radius exceeds 25 km. Multiple drives may be necessary in areas with dense traffic or obstructions.
