Hello yangjie,
If you have drawn the point shape on the orthomosaic and want to get it's coordinates on the source images you should at first use "update altitude" command from teh shape context menu in the Ortho view mode to ensure that shape vertex has all three coordinates and then execute the following code (providing that you have only one shape in the active chunk):

Code: [Select]
import PhotoScan
chunk = PhotoScan.app.document.chunk
shape = chunk.shapes[0]
T = chunk.transform.matrix
crs = chunk.crs
point = shape.vertices[0]
point_local = T.inv().mulp(chunk.crs.unproject(point))
for camera in chunk.cameras:
if not camera.transform:
continue
x, y  = camera.project(point_local)
if (0 <= x < camera.sensor.width) and (0 <= y < camera.sensor.height):
print(camera.label, str(x), str(y))

This code will output the XY coordinates of your original point shape on each image where this point is visible on.

Hello FredR,

I'm trying to understand, what is the problem. In the textured view when looking from below the ground in the textured mode you see the back-side of the single-sided surface. So you actually see the original texture, but from another side.

About the process: I tried to do that but is not possible to mark any GCP in the images because it doesn´t load.
The software only shows this notification:" loading thumbnail.."
I do no what to do. Can you help me please.
Thanks in advance...

Which version of PhotoScan you are using, what is the graphic card model mentioned in the Console pane as OpenGL rendering device and what is the driver version?

Thanks, I´ll do it.

While I was searching I read this (Extracted from: Agisoft photoscan pro_1_4_en):

"In the Reference preselection mode the overlapping pairs of photos are selected based on the
measured camera locations (if present). For oblique imagery it is necessary to set Ground altitude
value (average ground height in the same coordinate system which is set for camera coordinates data)
in the Settings dialog of the Reference pane to make the preselection procedure work efficiently.
Ground altitude information must be accompanied with yaw, pitch, roll data for cameras. Yaw, pitch,
roll data should be input in the Reference pane.

You can switch on both options to speed up the processing even more."


Can you explain me the bolded part please.
Thank you in advance.

The Ground Altitude parameter in the Reference pane settings dialog has meaning if you have complete exterior orientation information for the cameras: XYZ coordinates and orientation angles loaded to the Reference pane. In this case PhotoScan will use the Reference data and ground altitude value for the Reference preselection even for oblique images.

If you do not have orientation angles for cameras or no information at all is present, then Ground Altitude parameter will be ignored and would not help you anyhow.

Hello FredR,

Number of tie points practically does not have much influence on the mesh and dense cloud generation stages, as tie points are only used to identify, which pairs of images are overlapping and to estimate the general depth limits of the scene/object.

Hello jslyder,

Can you please specify the version of PhotoScan used and provide the line used for the messageBox call?

Hello FredR,

Do I understand it right: there are some polygons below the "ground level" that are textured? Does it still happen if you disable "hole filling" option in the Build Texture dialog?

Hello FredR,

If you are building mesh from the dense point cloud, then the main factor that effect on the memory consumption is number of points in the dense cloud.
For the experimental (visibility consistent) mesh generation method the quality used for the depth maps is important.
Additional factors are: working volume (i.e. bounding box size) and complexity of the model shape.

Hello dobedobedo,

Currently we are not planning to publish AUR packages.

The activation procedure for the node-locked license can be performed after the archive contents are unpacked:
Code: [Select]
./photoscan.sh --activate 11111-22222-33333-44444-55555to deactivate, use another command:
Code: [Select]
./photoscan.sh --deactivate

Hello smescarzaga,

Maybe you can also share the PDF reports from this project processed using nadir-only and nadir+oblique images?
Also do you have the camera calibration certificate?

General / Re: Not the best Pictures used in Orthofoto
« on: September 18, 2018, 07:28:51 PM »
Hello Dieter,

The main criteria that are taken into consideration when the images are selected for the certain area are:
- distance from the camera to the surface,
- smaller angle between camera normal and normal to the surface (mostly for mesh-based orthomosaic),
- distance from the source image center of the related area.

However, they are not considered consequently, but all at once.

In the given example the reason why other images are selected for the small elements could be related to the structure of the mesh model. You can try to use Smooth Mesh operation with some low Strength value to reduce the sharpness of the inner parts of the mesh.

General / Re: Dense cloud too big, how to reduce it?
« on: September 18, 2018, 07:21:53 PM »
Hello yoli,

Currently you cannot "decimate" the dense cloud in PhotoScan directly, so the only option seems to be exporting the cloud to external application, filtering out the points and importing the cloud back to PhotoScan.

Hello FHofer,
If the chunk labels are different in your project, you can use {chunklabel} macros in the path field, for example:
Code: [Select]
D:/projects/data/report_{chunklabel}.pdf
