The Design and Testing of a Lidar Platform for a Uav for Heritage Mapping

Abstract

ABSTRACT:In the discovering, identifying and mapping work of heritage objects in forest or desert areas, LiDAR ensures work efficiency and can provide the most complete and accurate 3D data. In the field of heritage documentation in China, the integration of LiDAR and small UAV is highly desirable. However, due to issues on the vibration of flying platform, load capacity, safety and other factors, not all UAVs can be used as LiDAR carriers. Therefore, the selection and design of suitable UAVs are very important. Little research has been done in this area and related experiments, complete test data and clear conclusions are hard to find. After long-term selection, design, trial-manufacturing and testing, the authors compare the vibration, capacity, reliability, stability of many UAV types, and finally develop two UAV platforms which are most suitable for carrying LiDAR for heritage mapping projects.

Evaluation and Calibration of Fixed-Wing Uav Mobile Mapping System Equipped With Lidar and Optical Sensors

“…Over the past years, new trends in the development of UAVs, referring to sensors, involved the application of ultralight laser scanners and integration of various sensors. Only a limited number of ultra-light, UAV-mounted laser scanning systems are described in research papers presenting the scanning systems developed within research projects (Wallace et al, 2012;Droeschel et al, 2013;Kuhnert and Kuhnert, 2013;Tommaselli & Torres, 2016;Torresan et al, 2018) and turnkey solutions (Glennie et al, 2013;Esposito et al, 2014;Li et al, 2015;Bakuła et al, 2016;Jozkow et al, 2016;Mittet et al, 2016;Salach et al, 2018). Examples of commercial solutions are presented in Pilarska et al (2016), but new types of scanning sensors dedicated for UAV platforms appear every year in the market.…”

The Potential of Light Laser Scanners Developed for Unmanned Aerial Vehicles – The Review and Accuracy

“…Besides the aforementioned error sources, more factors can affect the measurement accuracy; nevertheless, it is not possible to estimate their influence using the mathematical model. Included in this group is, for example, the vibration of the mechanical components of the sensor (Li et al, 2015). The temperature of the sensor may also play an important role.…”

A Survey of Practical Design Considerations of Optical Imaging Stabilization Systems for Small Unmanned Aerial Systems

“…In [8], with the objective to choose the most suitable sUAS for LiDAR mapping, the authors studied the vibration, capacity, reliability and stability of many sUAS platforms. With the acquired knowledge about the different platforms, they developed two sUAS especially optimized for the LiDAR mapping.…”
