iOS 17: How to enable and use screen distance on iPhone
Article Introduction:What is the screen distance feature in iOS17 update? Apple provides a screen distance function on the iPhone to help users prevent eye fatigue and the risk of myopia. The feature (available on iOS 17 or later) will use the iPhone's TrueDepth camera (the same camera that also helps FaceID) to measure the distance between the face and the phone. If Screen Distance detects that you are holding your iPhone closer than 12 inches or 30 centimeters for an extended period of time, it will prompt you to maintain distance from the iPhone screen. When your device detects that it is less than 12 inches from your face, you will see the "iPhone too close" message on the screen and advise that you should keep your distance to protect your vision. Only if you place the device further

From a technical perspective, let's talk about why binocular autonomous driving systems are difficult to popularize?
Article Introduction:Monocular vision is the magic weapon of Mobileye (ME). In fact, it also considered binocular vision at that time, but finally chose to give up. What do monocular ranging and 3-D estimation rely on? is the BoundingBox (BB) that detects the target. If the obstacle cannot be detected, the system cannot estimate its distance and 3-D attitude/orientation. Without deep learning, ME mainly estimates the distance based on the BB, the attitude and height obtained by camera calibration, and the assumption that the road surface is straight. With deep learning, the NN model can be trained based on 3-D groundtruth to obtain 3D size and pose estimates. The distance is obtained based on the parallel line principle (single view metrology).

How to turn on the eye protection feature in Apple iOS 17?
Article Introduction:For users who are concerned about healthy eyesight, there is now a feature in iOS 17 worth paying attention to. Apple has added a "screen distance" function to the iPhone, which allows the iPhone to sense the distance between the user's face and the phone screen. If it detects that the user's face is too close to the phone screen, it will trigger a reminder. This feature can be turned on in iPhone Settings - Screen Time: After turning it on, if the iPhone detects that your face is too close to the screen, it will issue a reminder: The reminder can only be turned off after returning to the appropriate distance: Application scenario: According to some users According to feedback, since it needs to be kept "at arm's length" from the iPhone, it is easy to trigger reminders after turning on this function, which may not be so suitable for daily usage habits. But if there is
