Traditional cars, because they are controlled manually, the driver’s perception of external environment, cognition, and control of the car are done by the driver. Or some more advanced cars with advanced assisted driving, which can be completed by the driver and the assisted driving system. However, for autonomous driving and driverless cars, because the vehicle itself occupies part or even all control of the car, at this time, it is necessary to rely on various laser pointer sensors installed on the car to work together to ensure driving safety.
At present, the sensors used by enterprises for self-driving cars are mainly the following: image sensors, lidar, millimeter wave radar, ultrasonic radar and biosensors. According to their different product attributes, they have different functions during the driving process of the autonomous vehicle to ensure the normal operation of the autonomous vehicle. This article introduces everyone to several major sensors in self-driving cars.
An image sensor is also called a photosensitive element. It is a device that can convert the green laser pointer optical image into an electronic signal. It belongs to the basic component category in self-driving cars. When acquiring an image, it must be used in combination with a digital camera in the early stage and later The support of image data processing system can provide the car with intuitive and realistic visual image information. Its specific working principle.
