KEYPOINTS GETTING MISMATCHED

dinesh.selvamoorthy · May 19, 2021, 6:08am

Dear community,
this is heavy dense vegetation area,
altitude : 50m
overlap : 85
sidelap : 80
instead of matching with correct place and keypoints , the data has been overlaid in the other place
there is no problem in capturing
can anyone just tell me how to solve this issue

Hello,

I’m looking forward to seeing responses to this issue as well. I am seeing similar in some subprojects of a very large data set I’m working on now.

Thanks in advance!

Hi Dinesh,

Thank you for sending the quality report.

The following steps will generally create a better result for areas of dense vegetation in your model.

Select the Ag RGB template.
Change your Keypoints Image Scale to 1/2 under Custom .
Keep the Internal Parameters Optimization at All . This setting is typically only changed if there was an issue in the previous set of results of step 1.
You can find more information in this article: How to improve the outputs of dense vegetation areas using Pix4Dmapper?

Cheers,
William
