LiDAR: state of the art and applications
The scouting activity was aimed at understanding the technical details of LiDAR technologies, analyzing their pros / cons and studying their characterizations according to the different possible applications.
The analysis activity allowed to define, through the study of the scientific literature on the subject, the set of available technologies and to understand their technical details: functional principles, limits, applicability and development perspectives. The main actors involved in the production or dissemination of these technologies were then identified and evaluated, through the analysis of professional databases (patent, scientific and other literature).
The analysis of the technologies was optimized according to the client’s requests and needs, raised in several moments of discussion, detailing the technical aspects according to the final application and the industrial sector considered. The results of the activity have allowed customers to understand existing technologies, to evaluate their characteristics and to select, with the support of CRIT, the most suitable solution for their application needs.
With the emergence of Autonomous Driving technologies, which have now come to define one of the main future trends in the automotive world, companies in different sectors have begun to focus more and more on the technologies enabling this change. Among these, LiDARs play a role of excellence, being among the key elements for allowing the identification, and sometimes recognition, of elements of the external world by automated systems. By providing these capabilities, LiDARs have gained increasing importance in numerous industrial applications, including safety systems and collaborative robots.
On the basis of the same operating principle, Time Of Flight (TOF) – which consists in sending light signals, generally through laser sources, and in the consequent analysis of the signal reflected by the objects present in the scenario under analysis – have been developed numerous architectures of LiDAR technologies. In fact, a fundamental part of the choice of the LiDAR technology suitable for a given application consists in the definition of the characteristics / KPI for the chosen application, such as field of view or resolution / latency.
In order to provide the tools suitable for choosing the optimal technology, a scouting activity was activated focusing on the analysis of existing technologies and on the details of the different architectures. In this way, the foundations were established for understanding technology and for choosing the optimal solution.
Subsequently, based on the requirements presented by the company and the applications of interest, the focus of the activity was shifted towards the specific characteristics for the case of interest. For example, the following were analyzed:
- specific differences between existing technologies
- formats used for data output
- safety standards relating to the use of LiDAR solutions
Finally, the main suppliers in the sector were listed and analyzed, giving a description of the activities and products offered. In this way, the existing landscape was defined and the necessary tools for future activities in this area were given
