Autonomous driving uses a variety of sensors to detect the surrounding environment and the driver’s condition in order to control the car’s movement.
Automotive sensing cameras play an indispensable role in autonomous driving by detecting vehicles, pedestrians, and traffic signs, etc. based on digital image data captured by cameras, and accurately controlling the vehicle.
Since the camera can only detect objects that can be imaged, it is difficult for the camera to detect images in situations that are difficult for humans to see, such as when the weather is awful and visibility is poor, or when direct light is shining into the camera. In such cases, light sensor technology called LiDAR can measure the distance to the object by measuring the disturbance and reflected light compared to the laser irradiation.
TAMRON is developing and manufacturing lenses for LiDAR as well as for sensing cameras.
