Embodiment 1

[0024] Embodiment 1 is used to identify and accurately superimpose registered objects.

[0025] see figure 2 , image 3 , Case of identifying the shaft hole with the virtual marking circle: turn on the AR device, identify the shaft hole, and pop up the virtual shaft hole marking circle after the recognition is successful, record the current world coordinates of the current virtual shaft hole marking circle with the current calibration controller coordinates, and assign the virtual shaft hole marking circle at the same time For the calibration controller, assign its real-time world coordinates to the target object coordinates of the calibration controller; at this moment, the current calibration controller coordinates and the target object coordinates should be the same. Move the virtual axis hole marking circle in real time by calibrating the controller's "up, down, front, back, left, right" buttons. At this moment, the coordinates and coordinate differences of the target obj...

Embodiment 2

[0027] Embodiment 2 is used to identify and register objects for precise navigation.

[0028] Precise navigation for the next step after the virtual marking circle marks the shaft hole: the principle is the same as that of embodiment 1. After the virtual marking circle marks the shaft hole, the navigation indicator arrow created in the program is also assigned to the calibration controller to identify the registered shaft After the hole is successful, move the navigation indicator arrow in the same way so that it can accurately point to the position of the next step, such as Figure 4 shown. The specific performance in the case is as follows: after the shaft hole is successfully identified, the virtual marking circle pops up. After the maintenance personnel accurately insert the ground wire into the shaft hole according to the 3D animation demonstration, the side prompts "Have the shaft hole work been completed?" After clicking "Yes", the above The virtual content of shaft ho...

Embodiment 3

[0029] Embodiment 3, used to identify registered objects and accurately locate dangerous areas to alarm

[0030] Alarm case of aircraft engine dangerous area: such as Figure 5 As shown, turn on the AR device and identify the whole aircraft. After the identification is successful, assign the fan-shaped dangerous area model made in advance to the calibration controller. The principle is the same as above. Move it to the tail of the aircraft engine to completely overlap with the tail of the aircraft, and then obtain the virtual sector. The world coordinate assumption a, the real-time movement coordinate assumption b of the first perspective of the AR device, by calculating the coordinate difference c=(a-b) in the program, when c Figure 5 , Figure 6 shown.

Abstract

The invention relates to a superposition method of virtual prompt information after artificial intelligence object registration and identification based on AR equipment. The method is characterized inthat a registered target object is identified based on a space positioning technology and a calibration controller of the AR equipment. According to the invention, accurate superposition of virtual information is realized, the precision reaches a centimeter level, a worker can conveniently carry out refined maintenance and inspection operation, accurate navigation is realized without the help ofthe Internet, and prompt of a dangerous area is realized without the help of sensing equipment.

Description

technical field [0001] The invention relates to artificial intelligence object registration and recognition technology, in particular to a superposition method and application of virtual prompt information after registration and recognition of artificial intelligence objects based on AR equipment. Background technique [0002] At present, AR equipment is mainly used in medical treatment, industrial maintenance, etc., and object recognition technology is often used. There are many types of object recognition, which are basically divided into image (2D) recognition and three-dimensional object (3D) recognition. In the end, it is very difficult to accurately superimpose the virtual prompt information on the target object. The main reasons are: [0003] In the process of using unity3D program development, the AR device is divided into world coordinates and relative coordinates. After the AR device is turned on, the virtual objects presented on the screen are all in world coordin...
