Camera Calibration / Re: Phantom 4 RTK - camera parameters

« on: May 14, 2019, 11:32:10 AM »

Hi Ana,

I too have had the same problem. However, if I use ground control points and undertake camera optimisation with all cameras and GCPs 'ticked' Metashape is able to determine the true parameters of the camera (unfortunately the parameters in the XMP data within the image file is a guide at best). I then save this camera calibration data and then use it for all my projects (with a couple of check points just in case). Results come out very good indeed.

If this is unclear let me know and i'll try to be more descriptive.

Regards,

General / Re: Systematic Z Error in Proportion to Altitude (Phantom 4 RTK)

« on: March 14, 2019, 05:49:35 AM »

I was wondering if there has been any progress made on this issue. I believe I am also encountering this Z error in proportion to height. If anyone has worked out a solution I would be very interested to learn more.

Feature Requests / GCP markers too small

« on: January 31, 2018, 12:20:15 AM »

Is there any reason why the GCP markers have to as small as they are? I find that having to move the mouse into that very small circle in order to select it for placement, and having to do this hundreds of times of a project, becomes very tiresome. Can the white small circles be made larger to make selection much less of a annoyance? Or can the marker be told to snap to the mouse instead of clicking and dragging the marker? Thanks.

Bug Reports / Mesh fail. Bug?

« on: October 10, 2017, 06:02:06 AM »

Has anyone ever seen a mesh generated like this before? The project is a typical aerial survey of a flat site, 80/80 overlap, 13 GCP's - all pretty standard. Align, and dense cloud generation all went as expected. Problems arose when generating mesh. I've attached images of the point cloud (which looks totally normal) and the resultant height field mesh generated from ground classified dense cloud points. I've tried the project in 1.3.4 and 1.40 beta with the same result.

Thanks

I have the same problem with my first project using version 1.3. Nvidia GTX 980 8GB VRAM.
