Feature Requests / Live Ground Classification Viewing Window

« on: January 30, 2019, 04:22:17 AM »

The Dense Point Cloud Ground Classification tool is great, but I find myself classifying, resetting, classifying, resetting, over and over and over again. While I understand what the 3 variable do (mostly), I always seem to have to tweak them to try and get the best results for ground classification.

A great feature to have would be the ability to sub-select a portion of your point cloud, then be able to apply nearly instantaneous changes to the cell size, angle, and vertical change variables to see how the ground classification changes based on the small changes. Once the low points are calculated based on the cell size, you could have sliders for the other 2 variables to watch how the changes affect the ground classification in real time. Then you could apply those variables to the entire dataset.

I know that the movement is towards automatic classification, but that appears to be a long way away at the moment. Having specific control over the point selection would certainly be a valuable tool to have.

General / Is there a way to reduce the arduous menu navigation?

« on: January 25, 2019, 10:45:49 PM »

Is there a way to pin a menu, add shortcuts, assign keystrokes, or anything else to reduce the constant menu navigation to the useful tools? I'm attempting to classify a point cloud and, if you've ever done this, it's a constant trial and error process.

This involves constantly going to:
    Tools->Dense Cloud->Classify Ground Points->[change parameters]->OK then Tools->Dense Cloud->Reset Classification... repeat until results are acceptable.

Having a button on the menu, or even better, an Apply option on the tool would be a much better solution. The same goes for "Select Points by Color" and "Filter Points by Class". It's a constant exercise in menu navigation and it's becoming tedious.

Is there a better way to do this, or is a Feature Request?

Thanks!

General / Getting XYZ Data from Point Cloud

« on: December 28, 2018, 06:37:53 PM »

Is there a way to get specific point data from the point cloud? I would like to be able to select a specific point and extract that positional information.

The only other answers that I've seen to this question suggest that you should add a marker and look at the estimated position. This works for the horizontal data, but the marker usually winds up floating well above the actual point cloud. Adding a marker to the mesh seems to be correct in the horizontal and vertical, but the mesh often doesn't contain the information that we need. Thanks for any help!

General / Not Enough Memory

« on: January 13, 2017, 10:01:41 PM »

I keep getting a "not enough memory" error while processing a small number of large format images. I have 18 .tif images that are ~130MB each (14144x15552) and I hit the error when trying to generate a High quality dense point cloud. The processing log doesn't seem to indicate any additional information, but I've attached it. I took a screenshot of the Task Manager's Performance window and it shows the point cloud generation is failing at less than 50% of the available memory. (The "not enough memory" error occurred during the last bump on the right.)

Is PS calculating how much memory is needed and then predicting that I don't have enough memory, or is there something that needs to be changed?

System: Intel E5-1660, 1080 GTX 8GB, 64GB RAM, SSD, PhotoScan Pro 64-bit 1.2.6 build 2834

Thanks for any help!
