[0002] Radar electronic equipment is the core equipment for realizing intelligent perception of national physical space security. Radar electronic equipment is rapidly developing towards high density and high integration. Currently, the trend of miniaturization, high power, and multi-functional integration of high-density radar equipment is becoming increasingly obvious. With the increasing performance requirements of radar equipment, there are more and more internal devices, higher density requirements, and smaller operating spaces. The requirements for assembly and maintenance are becoming more and more stringent. Especially when maintaining normally functioning radar equipment in a confined space, the harsh heat, air, noise, vibration environment, and electromagnetic radiation put great pressure on human physiology and psychology, and may even cause irreversible effects. This problem of high work intensity and uncontrollable work quality has brought unprecedented challenges to the assembly and maintenance of high-density radar electronic equipment.

[0028] Figure 2 This is a schematic diagram of an intelligent assembly and maintenance guidance system based on augmented reality provided in an embodiment of the present invention. Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1 As shown in the figure, an embodiment of the present invention provides an intelligent assembly and maintenance guidance method based on augmented reality, which includes the following steps:

[0032] S1. Collect assembly and maintenance images and corresponding assembly and maintenance guidance information, input them into the constructed assembly and maintenance model, generate a database, and collect real-world scenarios.

[0033] Before online assembly and maintenance begins, the functional process of augmented reality-guided assembly and maintenance is modeled to obtain an assembly and maintenance model. By collecting relevant assembly and maintenance images and corresponding assembly and maintenance guidance information, these are input into the constructed assembly and maintenance model, thereby generating a corresponding database for comparison and use during the online assembly and maintenance phase, and for collecting real-world scenarios.

[0034] The database contains information on the entire assembly process and operation and maintenance scenarios. The assembly and operation and maintenance guidance information includes the operation steps, tool information, and equipment names for the assembly and operation and maintenance process.

[0035] S2. Use computer vision to perform visual processing on the assembly and maintenance scenarios in the database to identify the assembly and maintenance targets.

[0036] Computer vision technology is used to perform visual processing on assembly and maintenance scenarios in the database. The visual processing is achieved by extracting typical features of the assembly and maintenance scenarios using the RGB-D camera in the Microsoft HoloLens augmented glasses. This includes the identification and tracking of assembly and maintenance targets, 3D scene reconstruction, and computer pose calculation. The identification and tracking of assembly and maintenance targets (i.e., equipment to be assembled or maintained) is the key part of this process.

[0037] S3. After solving the registration pose of the virtual guidance tool according to the assembly and maintenance goals, the virtual and real scenes are fused together to obtain the augmented reality assembly and maintenance scene.

[0038] After obtaining the registration pose of the virtual guide tool, it is fused with the real scene collected in step S1 to achieve seamless integration.

[0039] S4. Show augmented reality assembly and maintenance scenarios to the operators to provide assembly and maintenance guidance.

[0040] Augmented reality assembly and maintenance scenarios are displayed to operators through head-mounted displays to provide guidance.

[0041] It also includes steps for operators to control the virtual guidance tool through voice or physical gestures.

[0042] The method described in this invention utilizes Microsoft HoloLens augmented reality glasses, which are equipped with both RGB and depth cameras. Compared to traditional single RGB detection or grayscale detection, the RGB-D-based joint detection method integrates depth information of assembly and maintenance targets, effectively improving the speed, accuracy, and robustness of assembly and maintenance target recognition and scene reconstruction. This enhances the quality of equipment assembly and maintenance, shortens cycles, reduces costs, improves worker comfort and safety, and significantly improves the overall assembly and maintenance capabilities of high-density electronic equipment, thus promoting a shift in manufacturing models.

[0043] Example 2

[0044] A complete assembly process can be divided into two stages: the assembly planning stage and the assembly implementation stage. These two stages are usually handled by different departments. First, professionals plan the entire assembly process, and then the assembly line assembles the workpieces according to the planned assembly sequence.

[0045] The embodiments of the present invention propose, as follows: Figure 2 The illustrated intelligent assembly and maintenance guidance system based on augmented reality integrates planning, training, and guidance into a single system, thereby improving the efficiency of the integration between the training and actual operation phases. This includes:

[0046] The data acquisition module is used to collect assembly and maintenance images and corresponding assembly and maintenance guidance information, input them into the constructed assembly and maintenance model, generate a database, and collect real-world scenarios.

[0047] The assembly and maintenance object visual processing module is used to perform visual processing on the assembly and maintenance scenarios in the database through computer vision, and to identify the assembly and maintenance targets.

[0048] The virtual assembly and maintenance tool registration fusion module is used to solve the registration pose of the virtual guidance tool according to the assembly and maintenance goals, and then perform virtual-real fusion with the real scene to obtain the augmented reality assembly and maintenance scene.

[0049] The human-computer interaction module is used to display augmented reality assembly and maintenance scenarios to operators for assembly and maintenance guidance. Operators can then use this module to control the virtual guidance tool.

[0050] The human-computer interaction module is also used to provide functions such as structural analysis, problem detection, and learning and training of physical objects by combining augmented reality technology with AI.
