(2)Vision Department. Now let’s focus on the Department of vision, which could be better called Tesla, because it’s Tesla that achieves automatic driving relying on simple optical cameras and human-like vision. Its founder Elon Musk said at the social platform and annual meeting: "the radar scheme on the vehicle is extremely stupid. Anyone or enterprise using the lidar scheme will eventually fail. Their painstaking use of these expensive sensors is itself a trouble."
Tesla uses eight cameras to identify objects in the real world (the wild range is 360 degrees, and the monitoring distance can be up to 250 meters). The images obtained by the camera include pedestrians, other vehicles, animals or obstacles. Meanwhile, millimeter wave radar, ultrasonic radar and inertial measurement unit record the current environmental data of the vehicle, then send it to Tesla's autopilot computer. After calculating the algorithm, the autopilot computer transmits the speed and direction information to the steering rudder, accelerator and brake pedal to control the vehicle.
However, the content captured by ordinary monocular and binocular cameras are two-dimensional images, which lack depth information, so it’s hard to judge the distance of the object. In this regard, Tesla has also installed a forward-looking three-eye camera to judge the distance of the object by comparing the differences between the images of the two cameras through the on-board processor, and then conduct perception, segmentation, detection, tracking and other operations on the input image, which requires the real mace of the vision system - automatic driving algorithm.

Expanding mobile phone memory storage -Part 4
More and more manufacturers are releasing memory expansion on phones and this may enhance user experience to a certain extent, but there are also disadvantages that cannot be ignored.
The design that Apple has insisted on for more than 10 years is going to disappear? - part 2
First introduce the reasons why Apple is unwilling to abandon the Lightning interface, and from this draw forth the MFi certificate. Then introduce the purpose of Apple's MFI certificate and the author's interpretation of this purpose. Finally, introduce that the current fast charging technology is developing very rapidly, and Apple has fallen behind in this regard.
