RIEGL VZ600i

[dhirota]

Can't you run a batch process on it therough Irfanview or other? I presume these pictures are still in the same folder at each scan (SCANPOSIMAGES) as with a vz400i? Or is the structure of files reorganized with this 600i?

We can check it out, but the internal VZ600i camera is different in the number of images as indicated below.

Here are 3 images from a single location derived from RiSCAN PRO using a gamma correction of 1.5 using IrFanView 4.62 X64 version. Still need to figure out how the batch mode works and whether it will work by importing the images back into RiSCAN PRO directly.

I took your suggestion, and it worked, thank you very much.

This morning at 4:40AM HST, I discussed the work flow with Riegl USA's fabulous support person, Ms Blyte Babin to see if she could get it to work on a project with similar problems with our SAMS project. Riegl USA is fortunate to have staff like Blyte since she knows the system very well (it seems sometimes better than the folks in another country) and has the ability to communicate it in local USA English with visual workflows. She finished the test with a 12 page printed email describing what needed to be done at 9:40AM HST.

Mr. Raymond Sandla, our 3D Imaging Project Manager, took the work flow and created an IMPROVED image test of 5 scan positions (180 images, using the batch format to use the gamma correction of 2.2, and the rotation of images into the correct orientation). I then replaced the dark exposed images with the gamma 2.2 images in the RiSCAN PRO folder.

What you see below are screen shots of scan positions 003-to-007, RiPANO SP004 (location of the photograph of Josh Steinert and myself), and RiPANO SP007 (location of the other test images shown earlier).

So thank you again, Lieven for your suggestion, we collectively figured out how improve the imaging on a VZ600i, but we still do know know what happened to generate the problem.

Irfanview is one very strong piece of software. I use it all the time for these kind of things. Especially it's batch import.

And it's free.

Another Blyte Babin fix that someone in the other country has backwards.

You need to turn the "LIGHT SWITCH ON".... why is it not on already so the floor is not dark. I guess it it only for interior scans, since the outdoor scans you do not need to deal with the light switch??? in RiSCAN PRO. If you check above with the RiPANO, the floors are not dark, only with the OCTREE processed point clouds. I guess in some countries the sun is always shining outdoors.

We use Irfanview quite a bit to mass reduce the resolution of folders full of field photos of storm drain features for attaching in GIS data sets

I did not realize that he had posted it before I did, so I deleted my post. But after thinking about it, I decided that looking at the video is not going to give you any significant information of what the Riegl Tree Analyzer plugin will do for you unless you have Riegl's RiSCAN PRO running and are willing to pay more than a few US$ for the license.

After looking at the following visuals:

I decided I would give it a try, although my potential application would probably not work with Hawaiian trees. I will let you know if it works with Hawaiian trees, which generally do not look like those in the video.

The area scanned just looks to clean imho. It's a typical demo environment which doesn't represent the "real world" Over here all is always covered with low bushes and other stuff.

The area scanned just looks to clean imho. It's a typical demo environment which doesn't represent the "real world" Over here all is always covered with low bushes and other stuff.

We ended up developing a semi-automated tree extraction workflow for just this reason. Ground under trees is full of bushes and undergrowth, ground is very uneven, deciduous trees often fork into multiple trunks, trees put other trees in scan shadows etc... Automated works very well on clean data, particularly with large mature trees, but this only covers a certain percentage of use cases.

There has been a a great deal of information in the media (whether fake? or real?) about the fire in Lahaina, Maui, Hawaii on August 8, 2023. The major cleaning has been the commercial streets of burned cars.

We were requested by several people to see if we were willing to scan some historic features to document them before someone destroyed them intentionally or by mistake.

Ray Sandla, our 3D Project Manager has listed the reasons for scanning the Lahaina Banyan Tree. These reasons can be applied to other historic features.

Documenting the historic Banyan Tree in Lahaina, Maui, after it was damaged by the August 8 wildfire, is a crucial and meaningful undertaking. The following are reason why laser scanning can enhance the documentation process:

1. Preservation of Iconic Cultural Heritage: The Banyan Tree in Lahaina is an iconic symbol of cultural and historical significance. It has deep roots in the community's history and is a beloved landmark. Preserving its memory and legacy is paramount.

2. Accurate Documentation of Post-Fire State: Laser scanning provides an incredibly precise and detailed 3D color representation of the tree. This documentation allows for the recreation of the tree's post-fire state, ensuring that its historical record is not lost.

3. Assessing Damage and Preservation Needs: Laser scanning can accurately assess the extent of damage caused by the wildfire. It helps in determining the tree's structural integrity, identifying potential hazards, and assessing the preservation and restoration needs.

4. Historical and Educational Value: The Banyan Tree in Lahaina is not only a historical landmark but also an educational resource. Laser scanning can be used for research and educational purposes, offering insights into its growth, significance, and environmental context.

5. Supporting Restoration Efforts: Accurate laser scanning data can serve as a foundation for developing restoration plans. It ensures that the tree is restored in a way that respects its historical and ecological importance.

6. Public Awareness and Engagement: Visual documentation through laser scanning can be used to raise public awareness about the impact of wildfires on historical and natural landmarks. It can engage the community in preservation efforts.

7. Complying with Preservation Guidelines: Preservation guidelines often require the documentation of historical assets after they have been damaged. Laser scanning helps fulfill these compliance requirements and ensures that the preservation process is well-informed.

8. Future Generations: Documenting the Banyan Tree's post-fire condition ensures that future generations can appreciate and learn from this historic symbol. It helps pass on the cultural and historical significance of the tree.

9. Scientific Research and Analysis: Laser scanning data can support scientific research on tree resilience and recovery after wildfire events. It can contribute to our understanding of how to better protect and preserve historic trees in the face of natural disasters.

10. Collaboration and Community Bonding: Laser scanning efforts encourage collaboration between historians, environmentalists, community members, and preservationists. It brings together diverse expertise to work collectively toward the restoration and protection of this iconic tree.

In summary, using laser scanning to document the historic Banyan Tree in Lahaina, Maui, after the August 8 wildfire is not only a measure to preserve cultural heritage but also an opportunity to engage the community, advance research, and ensure that this beloved landmark continues to thrive for generations to come. You can see that the community + arbortist are taking significant greater care of the banyan tree and that it is growing leaves back after 6 weeks as seen in the scans.

The most significant problem in accessing the sites are government security. We also obtained Right-of-Entry permission for the private properties.

We used our Riegl VZ600i. Personnel with hazardous P-100 full masks, disposable shoe covering, and clothing just in case. We left HNL at 7:15A, arrived in OCC at 8:00A. We arrived in Lahaina at 9AM HST and started scanning at 9:20AM. The 162 scan positions were completed at 1PM, or 1.5 minutes per scan position. We protected the SONY camera + RTK GNSS with a zip lock plastic bag since Riegl has still not calibrated the SONY camera and the GNSS sensor worked with the plastic covering it. We placed the VZ600i, tripod and dolly in a plastic trash bag for hand-carrying it back on the plane, so it would not contaminate any cases, which were then removed for cleaning.

Below are shown the KMZ of the three projects (1. Lahaina Banyan Tree block, including Lahaina Court house, Fort Ruins, Lahaina Light house, and Pioneer Hotel; 2. Baldwin home- 200 year old missionary house + Meeting Room about the same age; 3. 700 meter, Front Street historic commercial area).
