Lu Fang, Chairman of Voyah: Four LiDARs Offer the Safest ADAS Solution Today

Lu Fang, Chairman of VOYAH Automotive, recently emphasized in a post that the core of intelligent driving safety lies in "seeing accurately," not merely "seeing." He pointed out that cameras rely on ambient light and are prone to failure in darkness, strong glare, or dense fog, making them a form of "passive perception." In contrast, LiDAR actively emits signals, enabling precise distance measurement and providing physical-level certainty. Lu noted that current chip computing power is far inferior to the human brain and should not force users to compromise safety to compensate for perceptual shortcomings. Although pure vision-based solutions require substantial computational resources, their reliance on "probabilistic inference" still cannot replace the "ground-truth data" delivered by LiDAR. He added that single or dual LiDAR setups inevitably leave blind spots, and only a four-LiDAR configuration can achieve full 360-degree coverage without blind zones, thereby ensuring comprehensive safety for users. Lu stressed that safety is not a cost issue—it is a matter of life and death—and that deploying four LiDAR units represents the most responsible and optimal solution for users at this stage.
