LiDAR (Light Detection and Ranging) is an innovative depth sensing technology which measures the time difference of emitted and received light signals. Figure 1 depicts the basic working principle of such a MEMS-based system: a MEMS mirror is used to deflect the emitted laser pulses. Photodiodes detect the reflected light. The light’s time-of-flight is determined with time-to-digital converters. Finally, post processing units provide point cloud information of the scenery (see also Figure 2) which is then be employed by use-case applications (e.g., assisted/automated driving applications).
In order to evaluate the performance of a sensor system, metrology tools are used. The aim of this diploma thesis is to develop a tool that supports basic metrology tasks (such as visualization of point cloud data, measurements within the point cloud, field-of-view analyses) for a MEMS-based LiDAR system. Furthermore, algorithms should be explored in order to perform a raw-to-point cloud conversion (used by the metrology tool) in an efficient and high performing way.
