I back you on this, Dieter. You are righter than right. The default behavior should be never overwrite, but only if user specifically wants to.

General / Re: Conversion from point cloud to mesh not working

« on: June 14, 2023, 01:49:24 PM »

Hi, Mark:
It looks like you are building the mesh from the sparse point cloud (tie points), you should rather use either "from depth maps" or "from dense point cloud" methods.
The latter will take longer, and the results may be slightly different but also in return you will have the opportunity to classify the dense cloud prior to mesh and filter by class the points you want to use for meshing.

General / Re: How to locate the corresponding 3d points of a pixel region of orthomosaic?

« on: May 13, 2023, 01:45:35 PM »

I think this could work only if a DEM exists. Draw a shape around the area of interest on the orthomosaic, right click and choose update altitudes. Then goto mesh and you'll see the shape in 3D, if you are on dense cloud you can also select points enclosed by shape, if that is your desire. If you want a more detailed shape projected onto the mesh all along the edges, and not just on the vertices, there's is a workaround as well.

General / Re: failure to assign marker points

« on: May 07, 2023, 12:57:16 PM »

I have the impression that your images do not have enough overlap, it seems overlap is under 50% and that leaves areas with zero overlap and that will make impossible to reconstruct. Is an image is reluctant to align but you are positively sure that it overlaps with aligned images, then you need to place at least 5 markers in that particular image connecting it to aligned ones.

General / Re: no tie points on road surfaces

« on: April 29, 2023, 12:13:21 PM »

The asphalt shows almost no features. I would suggest to use RAW->tif  to prevent compression artifacts and perhaps you manage to recover more details. To be honest I would be surprised if you had a clean flat surface out of this picture.

General / Re: Wrong camera calibration - adjusted focal lenght too off

« on: March 23, 2023, 01:48:58 AM »

Hello, michaldolnik
I suggest you to carefully inspect geotags.
I have seen some cases where really bad geotags are wrongly qualified as accurate as a few centimetres while just watching the coordinates one can see they are wrong.
When you load pictures in a new project you will see the blue balls representing camera locations. watch and see if there is any obvious blunder or misplaced ball.
if you see something suspicious, just uncheck the box for the suspicious photos. If they are tagged as accurate, they can potentially causing a strong bias in both exterior orientation and interior params.

Best regards
José

Thank you! That SP GUI typo is likely my fault, I'm sorry!
by the way, don't you think Omega Phi Kappa is the "right", the same fashion as XYZ is the right way for me whereas YXZ... is like driving on the left lane. Very much of an annoyance like nowadays is the entire English System of measurement. (personally: I think the whole world would benefit from banning non IS units whose survival in the globalized world only produces headaches and often catastrophic errors... even some English people privately agree)

I know we can use script to copy region from one chunk to another, but it would be useful to save it so it can be recalled easier.

General / Re: Fill holes in pointcloud?

« on: January 19, 2023, 02:55:40 PM »

Build a watertight mesh from depth maps, and then build a point cloud from the mesh (by sampling) with the desired point spacing... this workflow tends to deliver a much cleaner dense cloud.

Hi, Alexey, it happens consistently. New computer, 64gb ram. Sorage is ssd, Ryzen9, dual Gtx 1070ti, up to date Nvidia drivers... and occurs after depth maps are finished while mesh is being built. Will try same proj in my older computer.

General / Weird decimation

« on: January 13, 2023, 01:27:37 PM »

I've recently observed that during decimation metashape divides the whole mesh into regions and it looks it decimates diferently. It gives the impression that it sets triangle count per cluster as target rather than a global volumetric parameter for cutting the iterative reduction process, so it leads to very noticeable diferences in mesh resolution thus exactness between clusters.
I think there's room for improvement here.

General / Re: Dense Cloud to PTS (or e57, las etc) to RCS Problems

« on: January 09, 2023, 01:55:29 AM »

it shows just a long straight line of points

Very likely you are exporting geographic coordinates: lat/lon/elev and they are read in Recap as if they were X/Y/Z.
If you think a bit, you will surely understand why all your points look like a single line, or better, like a tall stack of points. They vary some metres in Z and barely move sub-microns in X/Y
