[0029] The present invention will be further described below in conjunction with the accompanying drawings and detailed implementation manners.

[0030] Refer to Figure 1 , which shows a schematic flow diagram of a 3D inverse imaging forming detection method for a hyperbolic special-shaped plate according to the present invention. The present invention provides a 3D inverse imaging forming detection method for a hyperbolic special-shaped plate 21, including:

[0031] Execute step S110: Assemble a plurality of hyperbolic special-shaped plates 21 into a panel 20 according to a preset model.

[0032] Among them, the surface of the hyperbolic special-shaped plate 21 usually has various curvature changes. The design details of the hyperbolic special-shaped plate 21 require high-precision processing to avoid uneven surfaces or shape distortion. The selected material of the hyperbolic special-shaped plate 21 is generally soft, and problems such as deformation and cracks are likely to occur during the stretching and bending processes. Careful installation is required during construction. Then, step S120 is executed.

[0033] Execute step S120: Use a scanner to detect the flatness of the inner surface of the panel 20.

[0034] Among them, the scanner is a 3D laser scanner, which requires construction workers to hold and scan. The inner surface of the panel 20 corresponds to the edge shape of the splicing of multiple hyperbolic special-shaped plates 21, and the height difference between the plate edges can be correspondingly detected. Then, step S130 is executed.

[0035] Execute step S130: Generate a first model based on the detection data of the scanner.

[0036] Among them, the inner surface of the panel 20 is scanned and imaged by the scanner to generate a 3D image of the curved surface splicing surface formed by the corresponding splicing of each hyperbolic special-shaped plate 21 in the panel 20. In this embodiment, the hyperbolic special-shaped plates 21 of different sizes and shapes can be scanned and imaged one by one in advance, which is convenient for subsequent corresponding data calling according to the shape of the splicing combination of the hyperbolic special-shaped plates 21 in the first model. Then, step S140 is executed.

[0037] Execute step S140: Compare the preset model and the first model with analysis software, and screen out the offset plates in the first model.

[0038] Among them, the screening conditions in the analysis software need to be preset by construction workers, and a data table is formulated according to the actual construction requirements, which is not specifically limited here. Then, step S150 is executed.

[0039] Execute step S150: Adjust the offset plates, and use the scanner to detect the offset plates again.

[0040] Among them, the adjustment scheme for each offset plate is made according to the deviation data, and each offset plate needs to be detected again after adjustment. Then, step S160 is executed.

[0041] Execute step S160: Repeat the above steps until the inner surface of the panel 20 meets the requirements of the preset model.

[0042] Among them, the offset plates can be adjusted specifically through the analysis software until all the hyperbolic special-shaped plates 21 are within the controllable deviation range of the data of the preset model.

[0043] Refer to Figure 2 and Figure 3 , Figure 2Shows the process schematic diagram before step S110 of the present invention. Figure 3 Shows the assembly structure diagram of the hyperbolic special-shaped plate of the present invention. The present invention provides a 3D inverse imaging forming detection method for hyperbolic special-shaped plates. Before step S110, it includes:

[0044] Execute step S1101: Build a model skeleton 10 on the ground and assemble the connecting arm 22. The connecting arm 22 can form multi-angle connections with the hyperbolic special-shaped plate 21.

[0045] Among them, the model skeleton 10 is floor-mounted, with a large load-bearing capacity, which can ensure the stability of the assembly process.

[0046] In this embodiment, the model skeleton 10 includes a base 11, a main rod 12, and a horizontal beam 13. The base 11 is arranged on the ground. The main rods 12 are vertically and spaced apart on the upper end surface of the base 11. The horizontal beam 13 spans and connects multiple main rods 12, and multiple horizontal beams 13 are arranged at intervals up and down. The position of the horizontal beam 13 corresponds to the splicing edge between the adjacent hyperbolic special-shaped plates 21 up and down. The model skeleton 10 further includes a strut 14. One end of the strut 14 is correspondingly connected to the side surface of the main rod 12, and the other end is connected to the upper end surface of the base 11. A reliable triangular stable structure is formed between the base 11, the strut 14, and the main rod 12. The strut 14 provides a supporting force for the main rod 12, which can ensure the stability of the main rod 12.

[0047] Refer to Figure 4 , which shows the process schematic diagram of step S110 of the present invention. The present invention provides a 3D inverse imaging forming detection method for hyperbolic special-shaped plates. Step S110 includes:

[0048] Execute step S111: Connect the connecting arm 22 to the outer plate surface of the hyperbolic special-shaped plate 21 correspondingly.

[0049] Among them, one side of the connecting arm 22 is connected to the end of the horizontal beam 13, and the other side is connected to the outer plate surface of the hyperbolic special-shaped plate 21.

[0050] In this embodiment, the connection angle between the connecting arm 22 and the horizontal beam 13 can be adjusted, and the connection angle at the connection between the connecting arm 22 and the hyperbolic special-shaped plate 21 can be rotationally adjusted, which is convenient for subsequent targeted fine-tuning of a single hyperbolic special-shaped plate 21. It is also set that the length of the connecting arm 22 can be telescopic, corresponding to adapting to hyperbolic special-shaped plates 21 of various sizes, with wide adaptability.

[0051] Refer to Figure 5 and Figure 6 , Figure 5 shows the process schematic diagram of step S120 of the present invention. Figure 6 Shows the structure schematic diagram of the panel of the present invention. The present invention provides a 3D inverse imaging forming detection method for hyperbolic special-shaped plates. Step S120 includes:

[0052] Execute step S121: inspect the flatness of the inner surfaces of the multiple hyperbolic special-shaped plates 21 one by one.

[0053] The joints between multiple hyperbolic shaped plates 21 also need to be tested to see if they meet the design requirements. In this embodiment, the vertical oblique seam width is set to 8 mm, the horizontal seam width is set to 20 mm, and the lower edge of the horizontal seam should maintain the absolute elevation difference between adjacent corners not greater than 1 mm. The joints of the hyperbolic shaped plates 21 must be re-measured to meet the error between the theoretical coordinates and the actually installed hyperbolic shaped plates 21, and the error must be controlled within 1 mm.

[0055] Execute step S122: adjust the height difference of the corner points between the left and right adjacent hyperbolic profiled plates 21 to be within the first interval.

[0056] Among them, in order to ensure a smooth transition between the horizontally adjacent corner points of adjacent hyperbolic special-shaped plates 21, during construction adjustment, a square ruler can be used to approach 10 mm from the outside of the installed hyperbolic special-shaped plate 21 to observe the height difference between the projection point of the adjacent hyperbolic special-shaped plate 21 and the edge of the square ruler. The first interval means that the height difference between the projection point and the edge of the square ruler is not greater than 0.5 mm.

[0057] See also Figure 8 , showing another flow chart of step S120 of the present invention. The present invention provides a method for detecting the 3D inverse imaging forming of a hyperbolic special-shaped plate 21, step S120 further includes:

[0058] Execute step S123: adjust the height difference of the corner points between the upper and lower adjacent hyperbolic special-shaped plates 21 to be within the second interval.

[0059] Among them, in order to ensure a smooth transition between the upper and lower adjacent points of adjacent hyperbolic special-shaped plates 21, during construction adjustment, a square ruler can be used to be placed 10 mm close to the outside of the installed hyperbolic special-shaped plate 21 to observe the height difference between the projection point of the adjacent hyperbolic special-shaped plate 21 and the square ruler. The second interval means that the height difference between the projection point and the square ruler is not greater than 1 mm.

[0060] See also Figure 9 , showing another flow chart of step S120 of the present invention. The present invention provides a method for detecting the 3D inverse imaging forming of a hyperbolic special-shaped plate 21, step S120 further includes:

[0061] Perform step S124: Adjust the plate joint spacing between adjacent hyperbolic shaped plates 21 according to the vertical plate joint interval and the horizontal plate joint interval respectively.

[0062] Among them, it is necessary to detect and adjust one by one between the hyperbolic shaped plates 21 from bottom to top and from left to right, which is convenient for operation, can effectively control the construction efficiency, and after the operation of adjusting and correcting the position of a single hyperbolic shaped plate 21, it is also necessary to re-detect the plate joints to ensure the accuracy and quality of the panel 20.

[0063] Refer to Figure 10 , which shows the flow schematic diagram of step S140 of the present invention. The present invention provides a 3D inverse imaging forming detection method for hyperbolic shaped plates 21. Step S140 includes:

[0064] Perform step S141: Calculate the preset skin data for the preset model through analysis software.

[0065] Among them, it is necessary to first import the 3D image drawing design of the preset model. The obtained preset skin data includes the curvature data of the inner plate surface of the preset model.

[0066] In this embodiment, the preset model includes the size data of hyperbolic shaped plates 21 with different shapes and the specific splicing setting positions. The adjacent hyperbolic shaped plates 21 match and correspond to each other, which is convenient for construction comparison.

[0067] Perform step S142: Calculate the inner contour data of the panel 20 through the first model of the analysis software.

[0068] Among them, the first model is a 3D image drawn according to the spliced hyperbolic shaped plates 21 in actual construction. The inner contour data correspondingly includes the size data of the spliced hyperbolic shaped plates 21 and the curvature change.

[0070] Perform step S143: Compare the inner contour data with the preset skin data to obtain the marked offset plates.

[0071] Among them, the offset plates refer to the hyperbolic shaped plates 21 in the panel 20 that exceed the deviation range. The deviation range can be set according to actual construction requirements and will not be specifically limited here. By comparing the inner contour data with the preset skin data, the position and deviation value of the offset plates can be directly obtained. The steps are simple and the efficiency is high.

[0072] Refer to Figure 12, showing another schematic flow chart of step S140 of the present invention. The present invention provides a method for detecting the 213D inverse imaging forming of a hyperbolic special-shaped plate, and step S140 further includes:

[0073] Execute step S144: Color-label the position and deviation value of the offset plate through analysis software.

[0074] Among them, the marked color can be set according to actual needs. In this embodiment, two opposite colors can be used to correspond to positive and negative deviations, and the degree of deviation can also be marked according to the depth of the color, which can enable construction personnel to intuitively feel and make corresponding adjustments, and can improve construction efficiency.

[0075] In this embodiment, for the first model obtained by scanning, the hyperbolic special-shaped plate 21 that meets the design requirements can be marked as green, while the screened offset plate is marked as red, with an obvious contrast, which is convenient for corresponding adjustments. For the deviation data generated by the analysis software, the data within the allowable error is marked as green, and the data exceeding the error is marked as yellow. In other embodiments, different colors can be selected for marking according to requirements, and no specific limitation is made here.
