![]() The order of the day is to work out the performance characteristics. The number of cars equipped with Luminar sensors hasn ’t been revealed, but the total would appear to be rather small at this point. The idea is that nonmoving devices should be cheaper and more resistant to degradation under road conditions. Velodyne’s lasers move visibly, rotating on the roof of the car, whereas most of the 60-odd lidar startups have preferred solid-state solutions. It uses just one widely sweeping laser and receiver‚ unlike the 128 laser/receiver pairs in the top-of-the-line product from Velodyne, the company that started automotive lidar and still dominates the market. Luminar is notable for basing its lidar on moving parts rather than solid-state methods, and for choosing a laser wavelength that's safe for the eyes and can thus be projected at high intensity. Luminar’s 250 meters of range provides 7-plus seconds notice at highway speeds, enough to slow even a big rig to a stop. Truck companies are particularly interested in long-range lidar because they stand to benefit from the stopping time that it makes possible. ![]() “A l ot of those are recent, very recent unfortunately most of them are not public.” “We have 18 different companies working with us and partnered with us,” says Luminar founder Austin Russell. Or flake out, on a fully reclining bed, like so: Then you’d just flip a switch and zone out until you reach your exit. In Volvo’s view of things, now being shown at the Los Angeles Auto Show, you’d have to get on and off the highway yourself (that’s the one constraint). Level 4 means the car can do everything under certain constraints, typically having to do with the place, the time, or the weather. The car, called the 360c concept, is still just a designer’s notion of how Level 4 autonomy would work under highway conditions. Here’s a little video illustrating the trick: ![]() It’s the sort of thing you’d need to know to confirm that an object is human, and then to guess which way he or she is likely to move. Luminar’s lidar is on display in a Volvo concept car, and the point is to show how the laser-based sensor dovetails with Volvo's system for reading pedestrians' body language.Īt the impressive distance of 250 meters, Luminar’s lidar can provide enough detail to let Volvo do what the carmaker calls “pose estimation.” This means getting an actual representation of a person, “including individual limbs, such as arms and legs-a level of detail not previously possible with this type of sensor,” Volvo said, in a release. ![]()
