Bug Reports / Frustrated with registration support. Thinking of switching

« on: April 06, 2022, 07:35:19 PM »

I'm hoping that posting here will provide better results than emails. I'm frustrated to the point of considering pirated software or an alternative such as Pix4D.

I had a hardware issue with my PC, and formatted it after replacing the GPU. I deregistered the licence properly, and activated it again after reinstalling. Unfortunately I had another issue and the stupid windows startup repairs wiped my HDD, and the activated license. Very frustrating. I've emailed support to get it opened up again but I'm just been given the run around. It's an edu licence, and I've traveled, work and studied at a few different places the last few years. I've always had my Gmail account registered because of this, but now this isn't good enough any more. I emailed from my current email address after being asked by support but now the school has blocked contact with RUS servers. I assume because of the war.

Support also previously sent me instructions to get information on my PC to do a manual activation, but the steps didn't work.

So now I'm stuck. I'm getting a lot of pressure to move away from Russian software, and this really isn't helping.

Cmon support. I'm trying here....

General / Hardware: i9 9900k vs i7 9700k

« on: February 27, 2022, 07:52:31 PM »

Hi all,

I have the opportunity to upgrade my CPU, and I'm wondering if it's worth it.  Would it be worth it to upgrade from a i7 9700K CPU to a i9 9700K? 

My specs are as follows:
AORUS Z390 mobo
i7 9700K CPU
Gigabyte 3070 TI GPU (just upgraded from a 2070 Super)
32GB Ram
2 x 2TB m.2 SSD

I want to get the most out of this system before I upgrade the entire thing. I can get a used 9700K for around $300, and I'm wondering if it's worth the upgrade. I've looked extensively ant the Puget Systems pages for comparisons, and the i9 9900k looks to be maybe 20% faster at most...but the newer CPU's from Intel and AMD seems to perform a LOT better than the 900 series from Intel.

Thoughts?

General / Nvidia Tesla K80. A good, cheap option?

« on: September 12, 2021, 05:39:34 PM »

As you all know GPU prices are insane right now, and I'm looking for a cost effective way to beef up an older second system to use for jobs.  I see that the Nvidia Tesla K80 has some pretty good specs, and is really cheap online because of the lack of monitor output. 

What would the K80 be comparable to? I have a 2070 Super in my main system. Doesn't anyone have any experience with this card? Possibly in a 2x or 3x configuration.

General / Trouble with UAV & Local Coordinate System Workflow

« on: July 19, 2021, 02:46:18 AM »

I'm having a ton of trouble with 2 data sets given to me by a client. It's been quite a while since I've done work like this, and the client has had issues with the data collection. 

The 2 data sets are of the same area, but at different times this year. There was an issue with the 1st data set in that some images did not save properly, so there is a gap in the data. The client want to use the data from the 2nd set to plug the hole in the 1st set. However, the 2nd set was completed with a different drone at a much lower resolution and lower overlap.  The 1st data set is almost 3 x the size of the fist in terms of photos and size. 1500 vs 3000 pics and 8GB vs 22GB.  The data was collected with 2 different model DJI drone.  There are also 15 GCP, which the client laid out and are triangles that 'point' to the mark. These are recorded in a local (m) coordinate system.  It's very time-consuming to find these because Metashape can't find them for me.

Before I can even think of plugging up the hole in the first data set, I need to be able to properly process them both...I think. Here is my workflow.  I cannot get the GCP to line up, after I mark them and update the transform.

1. Import images
2. Align images, remove any images that don't align properly, align again
3. Import reference: Local (m) .... now the client says' its meters anyhow.
4. Metashape creates the markers, and I spend the next 2 hours finding and marking the GCP with the 15 markers given to me.
5. Then the update transform function in the reference window. If I select Local (m) the markers are way above the 'ground' and not in the correct shape.  If I try with USft then it lines up almost fine, but the markers are now off by a few feet horizontally but below the surface vertically. 

How do I get the markers to line up with the GCP that are given in the local (m) datum?

This is where I'm stuck so far.  I know there is some kind of issue with how DJI records X axis/altitude data but I'm not sure how it apples with the scripts given by Agisoft. The data quality is poor, and I can't talk to the data collectors directly, or the people who laid out the GCP.

Any insight would be greatly appreciated.

General / Batch process DJI drone altitude(x) data...

« on: July 17, 2021, 08:18:04 AM »

Hi all,

I need to bach process a few hundred drone images, to convert the standard DJI measurment in feet to meters. I have GCP in a LOCAL coordinate system that uses meters, and I'm having a hard time. I found this script below in an old forum post, but it no longer works. Could someone please point me in the direction of an updated version? Or would one of the moderators be so kind as to update it.

This is my first job in a while 

Thank you!

Code: [Select]

#Solves EXIF altitude problem for imagery acquired by DJI drones
#For questions, get in touch with Agisoft PhotoScan forum user SAV
#Tested on PhotoScan Pro 1.4.0

import PhotoScan

doc = PhotoScan.app.document
chunk = doc.chunk

flight_height = PhotoScan.app.getFloat("Please specify the flight height in meters", 30)
take_off_alt = PhotoScan.app.getFloat("Please specify altitude above mean sea level for the point of take-off:", 0)

for camera in chunk.cameras:
if camera.reference.location:
coord = camera.reference.location
camera.reference.location = PhotoScan.Vector([coord[0], coord[1], flight_height + take_off_alt])

chunk.updateTransform()
PhotoScan.app.update()
print("DONE")

The script will first ask you for the planned flight height (it assumes that the survey occurred along a constant flight height, so no terrain following). Next, you'll have to enter the altitude above mean sea level for the point of take-off. It will then use the sum of both values to populate the altitude column in the Reference pane.

For example, if the point of take-off was 120m above mean sea level (AMSL) and the survey was planned at a constant flight height of 65m, then the altitude value would be 185m.

This script might help many DJI UAV users. Feel free to share this script/post.

General / $600 upgrade for Photoscan Pro machine.

« on: July 18, 2015, 06:06:52 PM »

Hi All!

My university department has a brand new HP Z440 tower. We would like to start doing small to medium scale processing of UAV images.  Typically what we can get from a 3DR Iris+ mission.  I have a budget of about $600 to upgrade the machine. Here's what I'm thinking.... 

Current specs are:

W7 64bit pro
Intel® Xeon® E5-1620 v3 (3.5 GHz, 10 MB cache, 4 cores, Intel® vPro™)
8 GB 2133 MHz DDR4 ECC Registered RAM (1 x 8 GB)
Nvidia Quatro NVS 925 Graphics
700w PSU
1 tb 7200 rpm HDD

I would like to add:

Nvidia 970 GPU $350 ish from Newegg.com
1 x 16bg ram + 1 x 8gb ram = 24 gigs ram (bring the total to 32GB) $250 ish from Newegg.com

Any thoughts or suggestions would be highly appreciated!

« on: May 06, 2015, 11:24:22 PM »

My university department wants to spend about $3000 on a workstation for Photoscan.  We plan to process UAV images.  Attached is my proposed build. Comments? Suggestions?

Motherboard is out of stock, but would be Supermicro X9DRD-EF Server Motherboard - Intel C602-J Chipset - Socket R LGA-201

Total of $2951

General / 16GB or 24 GB RAM for Photoscan

« on: April 10, 2015, 04:38:57 AM »

I want to use Photoscan for orthophoto and mapping purposes.  My laptop currently only has 8GB ram (4GBx2).  To speed things up, should I get another 4GBx2, or 8GBx2?
