Physical impairments in the operation of low-cost LIDARs

In recent years, the use of light detection and ranging (LIDAR) systems has grown exponentially due to their convenience for sensing applications. For a variety of applications, LIDARs performance degrades when they operate in environmental conditions such as rain, fog and snow. Complex processing and higher power are required to overcome these issues. Consequently, LIDARs are often inaccessible to the average consumer as this increases their cost. In this project, physical impairments due to varied materials and environmental phenomena are investigated in two low-cost LIDAR; the Benewake TFmini LIDAR Module (TFmini) and the Garmin LIDAR-Lite v3HP (LLV3HP). Using the results, the feasibility of these LIDARs in the application of advanced driver assistance systems (ADAS) is assessed. Results from these tests reveal that the TFmini and LLV3HP produce incorrect range measurements when different materials and environmental conditions are introduced. This project, therefore, demonstrates that low-cost LIDARs such as the TFmini and LLV3HP are not feasible for ADAS applications such as blind-spot monitoring and lane departure warning.
