Google’s Waymo, Uber and carmakers GM and Mercedes-Benz are among the companies that are helping to lower sensor prices that can reach US$75,000 (RM310,807).
By 2020, there will be more than 10,000 autonomous cars equipped with lidar sensors, which bounce laser beams off objects to figure out where they are in three-dimensional space, according to a report published Sept 5 by Bloomberg New Energy Finance. The scramble is prompting some of the world’s biggest technology brands – including Microsoft Corp, Samsung Electronics Co and Baidu Inc – to invest in lidar developers.
Self-driving cars typically use a combination of cameras, radar, lidar and ultrasonic sensors to navigate roads while avoiding pedestrians, vehicles and other objects. Lidar, first developed in the 1960s, can create digital topographical maps with higher accuracy and longer range than other 3D detection technologies. The sensors were used by the Apollo 15 mission in 1971 to map the topography of the moon.
The first generation of lidars used for automotive applications cost as much as US$100,000 (RM414,410) and had to mounted high atop car roofs so their spinning mirrors could achieve a 360º view. Some of today’s 3D sensors are based on solid-state technology without any moving parts, making them less prone to mechanical failure.
Since 2014, almost US$1bil (RM4.14bil) has been invested in lidar companies. While the bulk of funding – US$400mil (RM1.65bil) – has gone toward scanning-mechanical sensors, more recent funding favors solid-state technologies. Lidar doesn’t perform well in inclement weather such as heavy rain, according to Bloomberg NEF.
California-based market leader Velodyne Lidar Inc sells modules for US$8,000 (RM33,148) to US$75,000 (RM310,807), depending on the number of lasers they contain. More lidar makers are emerging in China, where Shanghai Slamtec Co promises prices as low as US$321 (RM1,330).
There also are a number of startups – such as Innoviz Technologies and Quanergy Systems Inc – trying to develop cheaper and smaller solid-state lidars, with price ranges as low as US$200 (RM829) per module depending on capability.
The US and China dominate the field, so far. Top US lidar makers include Ford Motor Co and Baidu-backed Velodyne, which expects to ship 1.7 million units by 2022. Chinese rivals include Shanghai-based Hesai, which counts Baidu and Microsoft Corp among its investors.
Samsung and Baidu are actively investing in lidar companies. Samsung’s Catalyst Fund and Ventures group is betting on the newer solid-state technologies, while Baidu Ventures has backed Velodyne and Hesai.
More than US$133mil (RM551.15mil) has been spent in lidar-related mergers and acquisitions since 2016, according to BNEF. That includes the buyout of Tyto Lidar by Uber Technologies Inc’s autonomous-truck subsidiary, and Continental AG’s acquisition of Advanced Scientific Concepts’ ASCar division, which developed 3D flash lidar and cameras
