3D Surface Features Scanning System with UAV-Carried Line Laser

Abstract

As one of the newest spatial information gathering methods, three-dimensional laser scanning technique is widely adopted in various fields due to its attributes of high accuracy and non-contact. However, currently, most systems of this kind are costly and with complex data post-processing requirements, which makes them not welcome enough for public usages. To deal with this, a novel terrain scanning system using line laser based on trigonometric survey is proposed. The system is capable of terrain data collection, data pre-processing, and 3D display. The data collection circuit is designed under Labview and PCL is applied for interface design. Collected data will be imported to the interface after pre-processing, thus providing the measured 3D terrain information. The experiment results show that the proposed system is capable of large area terrain scanning and display at a high speed and with low cost, and is more portable comparing to existing systems.
