Group 1: Industry Perspectives - Uber's CEO supports LiDAR for its lower cost and higher safety, while Musk criticizes it, claiming that sensor competition reduces safety [1][2]. - Baidu, a significant player in the autonomous driving sector, advocates for LiDAR, asserting it ensures driving safety and has cost advantages [2][14]. - The article emphasizes the division in the industry, with Waymo and Baidu favoring multi-sensor fusion (including LiDAR) and Tesla sticking to a pure vision approach [6][11]. Group 2: Technical Analysis - Tesla's transition from LiDAR to a pure vision system was driven by cost considerations and the belief that AI can surpass human driving capabilities using camera data alone [8][9]. - Waymo employs a multi-modal approach, integrating LiDAR, radar, and cameras, achieving L4-level autonomous driving and expanding its services in complex urban environments [11][12]. - Baidu's autonomous driving service, "萝卜快跑," utilizes a multi-sensor fusion strategy, combining LiDAR, cameras, and radar to achieve L4 capabilities, with a strong safety record [14][16]. Group 3: Performance Comparison - LiDAR systems provide high-precision 3D environmental perception, unaffected by lighting conditions, while pure vision systems struggle in adverse weather and lighting [48][49]. - The article outlines the advantages of LiDAR in terms of distance measurement accuracy, environmental adaptability, and reliable identification of static objects, contrasting these with the limitations of pure vision systems [50][51]. - LiDAR's ability to maintain performance in extreme conditions, such as heavy rain or fog, is highlighted as a critical safety feature for autonomous vehicles [34][36]. Group 4: Market Trends and Regulations - The article notes that the decreasing cost of LiDAR technology is making it more accessible for widespread adoption in high-end vehicles, with significant market players integrating it into their models [25][42]. - Regulatory frameworks are increasingly favoring the use of LiDAR in autonomous vehicles, with new standards requiring advanced sensing capabilities that LiDAR can provide [55][56]. - The collaboration between Baidu's "萝卜快跑" and Uber to deploy autonomous vehicles globally indicates a growing acceptance of multi-sensor fusion solutions in the market [18].
