However, under today’s conditions, the green laser pointer radar and millimeter wave have been completed to be very compatible. In addition, they form the “three swordsmen” of the sensor with the camera. Their functions are determined by their own nature. be lacked.
The millimeter-wave radar is mainly used for obstacle detection; it is difficult for the camera to obtain a model of a three-dimensional object, including its interference with the environment, which also depends on the impact of this light. For positioning, obstacle detection, object classification, dynamic object tracking and other applications.
Many friends think that with the rapid development of science and technology, the accuracy of radar is naturally higher the better. But I don’t know if it involves a misunderstanding. Taking lidar as an example, the data obtained is the key to judging the type of obstacles and the monitoring of objects in motion. If the accuracy is too poor, it will naturally be unrecognizable. We can all understand this. However, if the accuracy is too high, it will place very high requirements on the green laser pointer radar and even other parts of autonomous driving models. In addition to the increase in some unnecessary workload, the operating cost will also increase a lot. , May even shorten the life of the vehicle, so the sentence is still “no more, no less, just the right amount.”
