What can be applied to TOF?

2019-09-05
TOF application scenario:
vehicle electronics
In automotive applications, ToF can be used for autonomous driving, anti-collision automatic braking and OOP.
Supported by the time-of-flight (ToF) principle, the system accurately detects the driver's body and head position, even capturing his blinking action while wearing glasses or sunglasses to determine if the driver is sufficiently focused and positive. Fatigue driving, thus starting the corresponding countermeasures. For example, by vibrating the seat or warning tone. The less attention the driver has, the more attention the car will pay attention to. In order to respond quickly and accurately, the auxiliary system and emergency braking system can be activated automatically before a potential emergency occurs.
Mobile phone autofocus camera
Taking the ToF Sensor as an example in mobile autofocus, the conventional autofocus function usually uses a set of data calculation methods integrated in the mobile phone image signal processor. When the viewfinder captures the original image, the image data is transmitted to the image signal processor as raw material, and the image signal processor analyzes the original data to check the density difference between adjacent pixels in the image. Picking out the best frame of the image is the photo that appears in front of our eyes. The autofocus system using the ToF sensor focuses on detecting the distance between the object and the camera, reducing the number of image frames captured by the camera, and capturing images quickly and clearly even in low light. . In terms of shooting video, the movement within two meters enables accurate ranging and image capture.
