Elon Musk and Tesla have been known for their strong stance on relying primarily on visual recognition and artificial intelligence to power their Autopilot and Full Self-Driving (FSD) technologies, dismissing the need for LiDAR (Light Detection and Ranging) and, to some extent, radar. Musk has argued that achieving true autonomy requires a vision-based system that closely mimics human perception, which is why Tesla has invested heavily in advanced neural network processing to interpret the vehicle's environment directly from visual inputs.
The announcement in 2023 of Tesla incorporating a 4D image radar into their system marked a significant shift in their approach. This move suggests a recognition of the complementary benefits radar technology can bring to enhancing the robustness and reliability of autonomous driving systems, especially in challenging visibility conditions where optical systems might struggle, such as fog, heavy rain, or direct sunlight interference.
Why Tesla use 4D image radar and what is its advantage? In this article, I'll give a brief introduction to LiDAR and 4D image radar, delving into the heart of Tesla's strategic redirection and shining a light on the merits and limitations of these cutting-edge technologies.
