In March 2020, the new ipad pro released by Apple Inc. attracted a lot of attention, largely because of its innovative introduction of "Lidar scanning" as an image acquisition and positioning tracking module for AR technology.

The LiDAR used in the new ipad pro is mainly based on dTOF (direct time-of-flight measurement) technology, which has faster response speed, higher accuracy, better anti-interference ability and longer sensing range than iTOF (indirect time-of-flight measurement) technology.
However, the liDAR detection technology based on dTOF has high processing cost, larger volume and difficult integration, so the traditional liDAR detection is often used in scenes with low integration requirements. For example, the Furu optical FO-RSF-R100 scanning laser can achieve high-precision scanning of the surrounding 360° environment, which is widely used in robot vision, unmanned driving, regional warning and other fields.

The ipad pro uses VCSEL (vertical cavity surface emitting laser) and combines with Apple's precision machining technology, making it possible to apply lidar to electronic products and promote AR technology into People's Daily life.
What is AR?
Basic information:
Chinese name: Augmented realityEnglish name: Augmented Reality
Date of birth: 1950s and 1960s
Strengths: Seamlessly integrate virtual objects or information into the real world, bringing an immersive interactive experience
Main working principle:
Image acquisition module collects realistic environment images and uses algorithms for pre-processing;
The registration tracking and positioning system tracks the target in the real environment in real time to ensure that the virtual object is superimposed to the real environment with the correct perspective relationship;
Virtual objects are placed in the correct position and rendered by the rendering system, which seamlessly integrates the rendered information into the real environment through the virtual Fusion Reality system.
How can AR technology be applied in life?
Nowadays, online shopping is very popular, but the clothes bought by pictures may not suit your body; Buying offline not only takes time to queue for fitting, but also it is very troublesome to change.
AR technology can make the fitting process easy and fun.

clothing
In addition to AR fitting, major brands have also launched AR shoes, AR makeup, AR watch, etc., to bring consumers a better consumption experience.
The menu based on AR technology can show the food in a three-dimensional form, which is more authentic than the picture display, and can help customers more clearly perceive the size, color and shape of the food.

Apple's official AR decoration has brought great changes to the field of home improvement, users can scan the room through lidar and create a 3D model of the room, you can view the effect of different furniture in the room, effectively solving the problem of furniture style, color, size, placement.

Navigation is essential in today's social travel, but the traditional navigation can only obtain the user's location information, often appear to arrive at the destination but also in the vicinity of the trouble, especially in the 4D magic city of Chongqing, navigation is almost useless.
AR navigation can mark the route directly in the real environment, and can clearly guide users to change lanes, turn, go up stairs, etc., which greatly facilitates people's travel.
