Problems solved by technology
[0004] (1) For three-dimensional objects, it generally requires thousands of image samples to learn to achieve a 90% recognition rate through image recognition of an object, and the environmental conditions such as light are demanding; if you want to recognize different objects in the space one by one, the calculation The workload is huge;
[0005] (2) When encountering two parts with similar or even identical appearance, the two parts cannot be identified by the image;
[0007] (4) For hidden objects that are not visible from the outside, image recognition technology cannot be applied; for example, for objects placed in cabinets, image recognition technology cannot be used to place prompt information on them

Embodiment
[0081] Taking the inspection of equipment in the field of transportation facilities as an example, the specific application of the coordinate positioning-based operation guidance method and system of the present application in this field will be described below.
[0082] For transportation facilities, such as airplanes or automobiles, it is necessary to regularly inspect and maintain their components or important parts. During each inspection, the inspector will take the maintenance list and check the components listed on it one by one to confirm whether they are working properly. Component items that are not working properly are flagged by inspectors and await subsequent repair by operators. Since the important components on the traffic facilities are generally in fixed positions, the operation guidance method of the present application can be used to place and play prompt information. The specific steps can be:
[0083] (1) A positioning aid map for selecting a fixed posit...

The invention discloses an operation guidance method and system based on coordinate positioning. The operation guidance method based on coordinate positioning comprises positioning an assistant imagein a fixed position in a space to be operated, carrying out image positioning scanning on the space to be operated, extracting feature points inside the operation space, producing an image positioningfile, placing at least one virtual guide marker containing prompt information on a specified object in the space to be operated, loading the image positioning file and the virtual guide marker into the system after an operator enters the system, carrying out positioning in the space to be operated according to the visible positioning assistant image, acquiring the position and observation angle of the operator, and finding and playing the virtual guide marker by the operator under the guidance of the system. The operation guidance method has the advantages of low cost, rich prompt information, high recognition rate and small error.
Description
technical field [0001] The present application relates to an operation guidance method and system based on coordinate positioning, applicable to the technical field of industrial maintenance or inspection. Background technique [0002] In the industrial field, maintenance or inspection personnel often do not know how to operate complex equipment when inspecting and operating it, especially for new employees. Usually, you can only operate while flipping through the manual, but this kind of operation experience is very poor. In order to save time and energy, it often happens that the operator does not read the instructions and misuses with vague memory. According to the response of the on-site operators, the main means that can really help the on-site personnel is to place operation guidance information in places that need maintenance or inspection. This information can give the operator the most intuitive guidance, but in reality it is impossible to place the operational gu...
