Presentation

New tendencies in lidar technology for autonomous vehicles

The current state of development of autonomous vehicle technology requires a critical analysis of the requirements and key elements of autonomous driving systems, in particular, visualization systems. The report focuses on emerging trends in lidar technology to improve performance in autonomous vehicles. The new trends are flash principles of lidar with fast response; optical systems for laser beam distribution, in particular diffraction optics; a new method of obtaining information in the format of a visual camera with distance information (possibly in color), which makes it possible to analyze information based on AI without the stage of spatial reconstruction; and others. This also provides advanced engineering solutions, such as the absence of mechanical parts, miniaturization, power consumption and others.

The audience will learn:

  • The current state of autonomous vehicle technologies from the point of view of visualization systems
  • Novel tendencies in lidar visualization systems – principles and instrumentations
  • The lidar flash principle – pulsed illumination of the entire situation, reading the information in camera format and determining range
  • Key elements of advanced lidar sensors – laser light source on base diffraction optics, photosensors on base silicon photomultiplier
  • New information format and processing algorithms
