Lidar is a version of radar that uses laser light rather than radio waves to measure distance and although it may seem like a new technology, it’s been around since the 60s. It’s come to greater prominence recently as it’s been used as one of the sensing technologies both for 3D mapping and driverless vehicles. Jamie and Todd find out more about lidar from Wolfgang Juchmann, Director of Sales and Marketing at Velodyne LiDAR.
Velodyne LiDAR has been one of the leading companies developing lidar technology, bringing down both the size and price of the lidar units over the past ten years. What previously was the size of a dustbin, costing $80,000, is now the size of a large food tin and costs $8,000. As sizes and prices fall, the cost and practicality of autonomous vehicles becomes more feasible, with lidar building high resolution 3D maps of the world around the car. The on-board computer can use the 3D information to tell the difference between cyclists and buildings, and drive the car on the road avoiding other road users.
