Road Automated Modeling

Ensure that existing vectors are correct.

Steps

1.Click the Road Automated Modeling button.

2.A settings dialog box will pop up.

Parameters

• Topology Check: A prerequisite for automated modeling; all items in the check list must be in a completed state before modeling can proceed.

  • Check Road Area Polygon: Automatically checks if the geometric shape of the road area polygon is correct.
  • Check Internal Object Integrity: Automatically checks if internal vector objects, such as lane lines and arrows, are completely inside the road area polygon.
  • Check Non-closed Edge Lines within the Area: Mainly targets flowerbeds and solid barriers located within the road area for geometric checks, such as whether they are closed or have duplicate points.
  • Check Duplicate Points: All vector objects are checked for duplicate points, which can waste considerable computational resources and cause issues with constructing triangular meshes.

• Select New Area: Re-select a road area polygon.

• Check: Start the topology check.

• Terrain/Ground Markings/Ground Facilities: Select the content for modeling.

  • Terrain: If checked, automatically models the pavement, flowerbeds, and solid barriers.
  • Ground Markings: If checked, automatically models arrows, lane lines, crosswalks, etc.
  • Ground Facilities: If checked, automatically models facilities located on the ground, such as drainage grates and manhole covers.

  Note the distinction from regular facilities; ground facilities specifically refer to items like drainage grates and manhole covers that are situated on the pavement. Regular road facilities like streetlights, trash bins, and poles do not fall under this category.

• Detailed Settings: Detailed selection for terrain, ground markings, and ground facilities.

Detailed Settings

• Modeling: Begin automatic modeling of selected objects after passing the topology check.

Simple Case Study:

1.In the scene, refer to the Texture Manager to set MCode and SCode for each vector.

2.Click Check; if there are topology errors, the process will automatically stop and an error information display box will appear. The illustration below shows this.

Topology Error

If a topology error occurs, it will be indicated in the corresponding check item, and an error information dialog will automatically pop up at the bottom.

• Automatic Handling: Among the listed errors, some can be automatically fixed (e.g., duplicate points); others require manual adjustment, as prompted.
  • Recommended Actions: Manual or automatic actions are recommended. If automatic is suggested, "automatic" will be indicated.
  • Check Item: The check item where the error exists.
  • Error Description: A brief description of the error.

Double-clicking the error line allows for real-time location jumping.

3.After manual adjustments or automatic handling, click Check again until all check items pass.

4.Click the modeling button to perform automatic modeling.
