Since the above-mentioned message transmission method is understood by those with ordinary knowledge in the field, it is not the focus of this case, so the details will not be repeated.

The following content explains the usage of this preferred embodiment. It should be noted that, in this case, an aluminum plate 11 is used as the object to be welded, and the welding gun simulation device 3 is used to operate on the aluminum plate 11 to simulate the welding process. In addition, Unity software is used as the augmented reality interface 42 in this case. In this embodiment, the augmented reality interface 42 is designed as an APP and installed in a mobile device 12, and the augmented reality interface 42 is The touch screen of the mobile device 12 is used for control. The mobile device 12 is installed on the mask 41 and the lens of the mobile device 12 is used to obtain images.

First, turn on the start switch 22 of the electric welding machine simulation device 2 and turn the current adjustment button 23 so that the corresponding current value is displayed on the housing 21 and the user interface 53. Then, the operator holds the gun body 31 of the welding gun simulation device 3 with one hand, and moves the mask 41 with the other hand, and drives the lens of the mobile device 12 to aim at the gun body 31, so that the gun body 31 and the aluminum plate 11 appear in the expander. Within the augmented reality interface 42.

The welding scene detection module 421, the welding gun identification module 422, and the welding spot special effect control module 423 of the augmented reality interface 42 have the following functions:

1. Floor detection function (Vuforia Ground Plane), after accurately detecting the plane position of the aluminum plate 11 (the object to be welded), the welding special effects are accurately placed on the plane of the aluminum plate 11. Floor detection has the functions of detecting and tracking the horizontal plane, anchor point creation and tracking, and six-degree-of-freedom tracking. The detection method of the horizontal plane is to understand the basic geometric figures in the environment through the shooting picture of the lens, and detect the horizontal plane of the environment. The anchor point is a fixed position in the world space, through six degrees of freedom tracking to achieve continuous tracking as the world space grows and the ground plane changes.

2. Targets Vuforia Image, which detects the three-dimensional position of the aluminum plate 11. The fiducial point is captured through the lens, and the captured image features are compared with the previously captured data to get the image position. When using image targets, it is recommended to use images with high sharpness, clear outlines and rich details. The contrast and sharpness adjustments of the graphics can make the details of the image clearer. The location of the image can be detected and tracked by identifying the characteristics of the image. The user uploads the captured image to the Vuforia Target Manager to identify the sharp, tapered and contour details of the image, then integrate the data file, and then use the features captured by the camera lens and the known image features Data is compared, and images are detected and tracked. Therefore, it is recommended that the aluminum plate 11 and the circumference or body of the gun body 31 be pasted with a geometric pattern with sharp edges to facilitate identification and tracking.

3. Object target function (Vuforia Object Targets), scan the feature points of the gun body 31, obtain the feature data file and import the three-dimensional block formed by Unity, set the welding center 33 in the three-dimensional block to make the welding accurate The heart 33 can be accurately displayed in front of the gun body 31. The features of the welding gun captured through the lens are compared with the feature data of the object, and the location of the welding gun is found. Use Vuforia Object Scanner (Vuforia Object Scanner) to scan a physical 3D object to create an object target, place the object target on the scanning grid image to scan the feature points of the object, and upload the feature file to the target manager (Vuforia Target Manager), to integrate data files, compare the feature data of the object captured by the lens with the known feature data of the object, and detect and track the object.

Next, the operator presses the control button 32 of the welding gun simulation device 3 to perform a simulation operation of the welding operation. The control button 32 is a micro switch, which can simultaneously trigger the luminous element 34 to simulate the strong light emitted during welding, and the sound effect module 25 will also simultaneously generate welding sound effects. In addition, the control button 32 will also trigger the gas pump 24 of the electric welding machine simulation device 2 at the same time to eject gas from the gas pipe 35 to simulate the effect of argon gas jet during welding. The welding spot special effect control module 423 can present a corresponding welding special effect on the aluminum plate 11 according to the value of the current adjusting button 23, the length of time the control button 32 is pressed, and the moving direction of the welding center 33, for example: Single point welding, the size and color depth of the welding point, fish scale welding and so on. Among them, the larger the current value, the longer the time the control button 32 is pressed, and the welding point will expand accordingly.

In the process of welding simulation, the operator can also perform welding quality grading operations. Through the solder joint special effect control module 423 of the augmented reality interface 42 and the image processing module 52 of the solder joint quality scoring device 5, the world coordinates of the upper left, upper right, lower left, and lower right corners of the aluminum plate 11 are obtained , And after sorting the coordinates of multiple welding points according to the X-axis value from small to large, the X value and Y value of the world coordinate of each welding point are calculated by the following formula to calculate the distance from the previous welding point:

為兩相鄰焊接點的圓心之間的距離，r則為焊接點之半徑。判斷流程包括： Refer to Figure 4 for coordination, where,

It is the distance between the centers of two adjacent welding points, and r is the radius of the welding point. The judgment process includes:

後判斷是否大於焊接點的直徑，若大於焊接點直徑則表示焊接點之間不夠密合而給予扣分。 Step 1: Obtain

Afterwards, it is judged whether it is larger than the diameter of the welding point. If it is larger than the diameter of the welding point, it means that the welding point is not close enough and will be deducted.

Step 2: Calculate the ratio of the diameter of all welding points to the width of the aluminum plate 11. If it is lower than the built-in threshold value, points will be deducted to avoid the situation where only one or two points can be welded to get a high score.

Step 3: Define the entire X-axis at the center of the aluminum plate 11 as the welding standard. If the welding point deviates from the welding standard and exceeds the built-in threshold value, points will be deducted. Finally, the scores of the above three steps are summed up and the final score is calculated, and the simulated welding result on the aluminum plate 11 and the final score are displayed on the user interface 53 to let the operator know the training result this time.

Through the above design, the new welding simulation training system combines somatosensory interaction, augmented reality, and virtual reality. As long as the augmented reality interface 42 is installed in the mobile device 12, the mobile device 12 is installed. It is installed on the mask 41 and cooperates with the electric welding machine simulation device 2 and the welding gun simulation device 3 to perform welding simulation exercises. The operation process is easy to get started, and it fully provides solid somatosensory feedback such as strong light and jet, and can avoid the risk factors of actual welding such as burns and strong light stimulation. The simulation results can then be evaluated by the scoring mechanism to provide objective scores. To enhance the learning effect, the overall equipment cost is also far lower than the welding simulation equipment on the market, and it can indeed achieve the goal of new cost.

However, the above are only the preferred embodiments of the present model, and should not be used to limit the scope of implementation of the present model, that is, simple equivalent changes and modifications made in accordance with the scope of the patent application for the present model and the description of the model, All are still within the scope of this new patent.
