General / 3D Scanning Masterclass Dataset

« on: November 09, 2024, 07:16:12 PM »

Hi Everyone,

I am putting together a comprehensive collection of coursework on 3D scanning and I have produced two large datasets.  The first is 100gb of DSLR photography from Joshua Tree National Park and the other is close to 1tb of data from the abandoned George Air Force Base in Victorville, CA.  The George AFB data includes high and low altitude drone capture, 6 lidar scans from the Navvis VLX3 and MLX units including raw fisheye imagery and 44 lidar captures from the BLK360 gen2 unit from Leica.  In addition, there are over 800 raw DSLR photos and 700 360 raw images from the Qoocam Ultra 3.

UPDATE:  High traffic has caused me to cut/reduce access.  My apologies, give me some time to come up with a solution.

General / Laser Scans Have Non-Unit Scale

« on: October 12, 2024, 06:27:04 PM »

So, I have created a point cloud from drone RTK imagery, and the accuracy is pretty good with point cloud reconstruction.  When I try to set it as a laser scan so I can align with another scan, I get a "Chunk or some laser scans have a non-unit scale which will be reset" error


2024-10-12 08:23:44 chunk scale: 9.70177, point cloud 0 [mavic3e_2024-06-22] scale: 1, total scale: 9.70177 = 9.70177 * 1

Ideas?

I was able to resolve the error.

Unsupported datum transformation error when importing Navvis VLX3 e57 file.  No error in version 2.1.3

Jeff

Now when I roll back to 2.1.3, then try to open this reference as WGS84, I'm getting the same error.

General / Metashape Training Suggestions

« on: August 07, 2024, 03:32:22 PM »

Hi All,

I am putting together quite a collection of tutorials for my 3d Scanning Masterclass.  I've got the outline for my introductory videos done and starting to work on the advanced coursework.  I'll be processing all of the lessons in Reality Capture, Zephyr and mostly Metashape.  Any suggestions for lessons would be greatly appreciated.

More information can be found at https://jeffreyianwilson.com/.

Thanks!

Feature Requests / Re: Google 3D Tiles

« on: February 18, 2024, 08:10:19 AM »

While I'm on the subject, is there a way to set an imported 3d model with WGS84 GPS coordinates?  I used Blender BLOSM to create a mesh from Google 3D tiles and I want to assign the proper GPS coordnates so I can use it in mission planning.

Feature Requests / Google 3D Tiles

Hi Agisoft Team,

Please consider supporting Google 3d tiles.  It would be good to be able to use the 3d tiles to do basic mission planning for drones.

My particular app favorite is Pix4D Catch.  It's free and gives you live feedback during scanning, RGB, Depth, CSV trajectory, mesh and point clouds.  I will be developing a tutorial which shows how to use the data and process output for splats and nerfs in NerfStudio.  If you have an RTK Vidoc, it's a fantastic addition.

Feature Requests / Block Processing Iterative Save

« on: January 31, 2024, 05:26:10 PM »

Hi Agisoft Team,

I would like to suggest an iterative save feature during block processing and the ability to pick up processing if a session is dropped or system crash.  Nothing is worse than losing weeks of processing on very large aerial scans.

Thanks,
Jeff

General / Metashape 2.1 Block Processing

« on: January 21, 2024, 07:03:13 PM »

Hi Agisoft Team,

I absolutely love the new block processing feature.  I wrote a lot of python to do something similar albeit nothing as nice and tidy as this feature.  Massive aerial captures just got a whole lot easier to process and a much more manageable Cesium/3D Tiles workflow is within grasp.

Kudos!

Feature Requests / Re: True Mosaic Texturing

« on: November 08, 2023, 11:07:34 PM »

Hello Jeff,

Do you have any sample dataset that you can share for our internal analysis of the problem and testing possible ways to fix it?

The samples I have are show NDA and can't be posted here.  Is there an official email I can send through to get NDA's signed?

Feature Requests / True Mosaic Texturing

« on: November 07, 2023, 08:03:09 PM »

Texturing has always been one of Metashape's weaknesses, especially with sparse photography.  I would like to request a feature for mosaic texturing where MS uses a single camera per polygon taking the sharpness of that camera view into account.

Thanks,
Jeff

Most rendering engines allow you to bake into proxy geometry such as VRay vrmesh,

General / Pano / Cube Map Setup

« on: October 26, 2023, 07:37:06 PM »

Hi All,

So I've setup a camera rig with a panorama as the master camera and cube faces as slave cameras then set the fixed parameter values as the cube faces are considered pinhole cameras.  My question is, how do I export only the cube map cameras from the rig, ignoring the panoramas?
