Abstract

A method for generating an interactive 2D projection of a 3D model includes steps of applying hierarchical defect data to the 3D model of a multi-part object, generating heatmap data based at least in part on the hierarchical defect data, and overlaying the heatmap data on the 3D model. The method also includes steps of extracting data corresponding to the 3D model and including the heatmap data after the overlaying step, and creating the interactive 2D projection based on the extracted data.

First claim

What is claimed is:

1. A method for generating an interactive 2D projection of a 3D model,
wherein the method is performed by one or more processing devices, the method comprising:
applying hierarchical defect data to the 3D model of a multi-part object, the hierarchical defect data includes a defect count applied to a child/parent pair of parts;
generating heatmap data based at least in part on the hierarchical defect data;
overlaying the heatmap data on the 3D model;
extracting data corresponding to the 3D model and including the heatmap data after the overlaying step; and
creating the interactive 2D projection based on the extracted data that includes the hierarchical defect data for the child/parent pair of parts.

2. The method of claim 1 , further including using a translation model to convert the extracted data to the interactive 2D projection.

3. The method of claim 2 , wherein generating the translation model includes estimating a camera-to-canvas distance for each part of the 3D model being converted to the interactive 2D projection.

4. The method of claim 1 , wherein the applying step includes applying defect data to the 3D model from a bill of materials.

5. The method of claim 1 , further including using an automation to perform the applying step.

6. The method of claim 1 , wherein the extracting step includes extracting:
2D image data; bounding box coordinates of each part of the 3D model being converted to the interactive 2D projection; and a camera-to-solid model surface distance for each part.

7. The method of claim 1 , further including displaying the 3D model on a first computer display using a first data visualization software program.

8. The method of claim 1 , further including displaying the interactive 2D model on a second computer display using a second data visualization software program.

9. The method of claim 1 , further including integrating first and second data visualization software programs such that a modification in one of the first and second data visualization software programs is reflected in a second of the first and second data visualization software programs.

10. A system comprising:
at least one processing device, the processing device being programmed for generating an interactive 2D projection of a 3D model, the processing device being programmed for executing the steps of:
applying hierarchical defect data to the 3D model of a multi-part object;
generating heatmap data based at least in part on the hierarchical defect data, the hierarchical defect data includes a defect count applied to a child/parent pair of parts;
overlaying the heatmap data on the 3D model;
extracting data corresponding to the 3D model and including the heatmap data after the overlaying step; and
generating the interactive 2D projection based on the extracted data that includes the hierarchical defect data for the child/parent pair of parts.

11. The system of claim 10 , wherein the processor is further programmed to utilize a translation model to convert the extracted data to the interactive 2D projection.

12. The system of claim 11 , wherein the translation model includes an estimation of a camera-to-canvas distance for each part of the 3D model being converted to the interactive 2D projection.

13. The system of claim 10 , wherein the hierarchical defect data is extracted from a bill of materials.

14. The system of claim 10 , wherein the processor is further programmed to automate the step of applying the hierarchical defect data.

15. The system of claim 10 , wherein the extracted data includes: 2D image data; bounding box coordinates of each part of the 3D model being converted to the interactive 2D projection; and a camera-to-solid model distance for each part.

16. The system of claim 10 , further including a first data visualization software program for displaying the 3D model on a first computer display.

17. The system of claim 16 , further including a second data visualization software program for displaying the interactive 2D model on a second computer display.

18. The system of claim 17 , wherein the first and second data visualization software programs are integrated such that a modification in one of the first and second data visualization software programs is reflected in a second of the first and second data visualization software programs.

19. A method for generating an interactive 2D projection of a 3D model,
wherein the method is performed by one or more processing devices, the method comprising:
applying manufacturing metadata to the 3D model of a multi-part object, the manufacturing metadata including hierarchical defect data including a defect count applied to a child/parent pair of parts;
generating heatmap data based at least in part on the manufacturing metadata;
overlaying the heatmap data on the 3D model;
extracting data corresponding to the 3D model and including the heatmap data after the overlaying step; and
creating the interactive 2D projection based on the extracted data that includes the hierarchical defect data for the child/parent pair of parts.

20. The method of claim 19 , wherein the manufacturing metadata includes hierarchical heatmap data.
