Python and Java API / Floating license not recognise

« on: May 28, 2023, 03:11:54 PM »

Hi, I just installed Metashape Pro on a new machine and there is no way to get it to read the license from the server (it is in a classroom with 20 other computers that are connected to the license server and work properly). Any idea how to fix it?

General / Set bounding box from shapefile

« on: February 19, 2023, 12:41:55 PM »

Hi! Is it possible to set a bounding box from the maximum and minimum coordinates of a shapefile? I want to obtain a dense cloud of a small area of my project

General / Assign RGB to a multispectral point cloud

« on: October 14, 2020, 03:44:18 PM »

Hi! I'm trying to create a point cloud from images taken with a Micasense RedEdge camera, but once I perform the radiometric calibration, the RGB colors in the point cloud are modified to a false color. Do you know how to fix this?

I don't know if it is related with this issue, but if I export the dense point cloud normalized (applying the B1/32768 and so on formulas in the raster transform), the color values for the points are very low:

Camera Calibration / Radiometric calibration before point cloud export

« on: October 17, 2019, 11:05:50 AM »

Hello, I'm working with the images from a Micasense RedEdge and I have a question about the workflow. Currently I'm doing the radiometric calibration as first step of the process, later I align the photos and immediately I densify the point cloud.

After the densification, I export the point cloud to a .txt file. Could you let me know if the colours exported are being radiometrically corrected before the export?

Thanks!
