Where is the iphone 13 lidar scanner and how to use it?

The usage of Apple Lidar scanner is as follows:

1. Turn on the rangefinder, aim the origin of the lens at the starting point of the measured object, and press+to mark the starting point. Move the phone slowly, and when it reaches the end point, click the+sign to end the measurement.

2. Open it and click to enter "Camera". Adjust the position of iPhone so that the tested person is displayed on the screen from head to toe. After waiting for a moment, a line is displayed on the top of a person's head (or the top of a hair or hat), and the height measurement result is displayed directly below this line.

IPhone lidar features:

The function of lidar is accurate ranging. The lidar scanner has both a laser generator and a laser receiver. The principle is to emit a laser. When the laser touches an actual object, it will form a reflection, and then the receiver can feel the reflected laser.

Since the time of laser emission and reception is recorded and the speed of laser is known, the time of laser reflection can be converted into the actual distance from the object. Not only that, the accuracy of lidar ranging can be as accurate as a few centimeters.

The function of lidar is to obtain the actual distance and orientation of the object, and the camera is undoubtedly capturing the picture. So when the two are combined by software, the picture on the screen is not only an image, but also the data such as the distance of the object are recorded in iPhone 13Pro.

Because AR itself is a combination of virtual and reality, iPhone 13Pro can capture real objects more accurately and obtain more data, and the application of AR technology can be more accurate and mature.
