3D lidar is such a kind of born from functional innovation. Started to enter the commercial development of laser pointer sensors. Let's take lidar as an example to sort out the typical development trend of sensors. R&D trend 1: Technology is extended to higher levels. The emergence of 3D lidar is to meet the needs of the system for real-time spatial perception. Autonomous mobile robots such as driverless cars and unmanned aerial vehicles are used for the purpose of spatial recognition, autonomous obstacle avoidance, and route planning. A sensor is needed to scan the surrounding environment in real time. In order to know the distance information of surrounding obstacles and roads, 3D Lidar came into being.
The development process of 3D lidar is essentially the upgrading of laser ranging technology. And the gradual escalation process of the realized demand. Laser ranging technology is the basis of 3D lidar. The first laser rangefinder appeared. It solves the need for point-to-point one-dimensional distance measurement; then the emergence of 2D lidar solves the need for sensing close objects in a fan-shaped plane, measuring the distance in the plane; now 3D lidar, through high-speed change laser projection angle. Scan the surrounding environment in real time to obtain distance information. It solves the obstacle and environment recognition needs in three-dimensional space, and measures the distance in three-dimensional space. The most popular area of 3D lidar applications is unmanned vehicles.
