Design and Implementation of Multi-sensor Integrated 3D Laser Scanning Data Acquisition System

A LiDAR system is combined by various kinds of sensor systems. And the real-time data acquisition of multi-sensor is the basis of it. According to the characteristics of data acquisition for multi-sensor integrated mobile LiDAR system, we use Qt as development platform and adopt serial communication programming technology and multi-thread technology to achieve real-time data collection and preservation of the mobile 3D Laser Scanning Measuring system. Compared with the existing system, we designed 3D Laser Scanning Data Acquisition System overcame the inconvenience that we need to start each sensor data collection program individually and difficult for the data synchronization. In addition, this system also has superb portability. It can also be applied to other operating system supported by Qt such as Linux, Windows CE, etc. Finally, the experiment results show that this 3D Laser Scanning Data Acquisition System operation is stable and reliable, it could collect and preserve different kind of sensor data simultaneously and meet the application needs.
