Improvements in Model Generation Process

Improvements in Model Generation Process

Successful model generation is the base for any action in DatuBIM. We are constantly improving our model generation process. Most of these improvements occur within the process itself and may not be visible on the model generation wizard’s interface. However, this time is different. Our improvements are both internal and external, including a better workflow, additional and improved warning and error messages, automatic fixes for some cases, and so on. Here is a summary of the notable improvements:

  1. Marking stage now offers 3 sorting options for each GCP:
    1. Suggested images – displaying the best 6 images identified by AI. This is the default option when possible.
    2. All images that hold hints or images that are already marked.
    3. The closest images based on image geo-location, with hint images first.
            It is highly recommended to mark 5 images for each GCP. Select images that vary in angle and where the GCP is as close as possible to the center.
            

      2. Every selected image with a hint will automatically zoom toward the hint. It is highly recommended to zoom in further and mark the exact center pixel of each GCP.
            

      3. After manually marking all GCPs, run the “Check accuracy” process.

      4. Warning about high E/N or H residuals
            

      5. Warning about insufficient or poorly distributed marked GCPs or monuments:
            

      6. In case of high residuals when using AI, the system will recommend manually validate the GCP markings:
            

      7. Warnings about height differences, gaps between images, and low-quality RTK:
            

      8. Automatic identification of an incorrect coordinate system ahead of processing. In such cases, the following message will appear:
            

      9. If high residuals are calculated, follow the warning and error messages (as demonstrated earlier on this document). After following the instructions, run the new “Improve & revalidate accuracy” process.
            The new process will:

a. Optimize the RTK flag selection according to RTK quality

b. Optimize the rolling shutter flag selection according to camera type and/or flight speed

      10. If previous attempts were made to improve the accuracy but none succeeded, the system will offer the following:
            
      Successive attempts will be possible afterwards, but unless dramatic changes are applied, there is a little chance the model can improve much further.

 

In summary, the latest enhancements to DatuBIM’s model generation process deliver significant improvements both behind the scenes and in the user interface. With new sorting options for GCPs, refined accuracy checks, and smarter optimization processes, these updates are designed to streamline workflows and improve overall model quality. By following the new recommendations and utilizing the 'Improve & Revalidate Accuracy' process, users can ensure that their models achieve the highest level of accuracy and reliability.
