Init calibration with blender benchmark #1
Conversation
|
I got "Engine 'BLENDER_EEVEE' not available for scene 'Scene' (an add-on may need to be installed or enabled)" for Blender . Most probably I need to update it. I used ubuntu 18.04 and default Blender version. |

Please add reference to OpenCV repo where to get gen_pattern.py and refererence to ImageMagick is required. At least apt-get install ...

I updated Blender and it almost works for me now. Couple of notes:
|
calibration_with_blender/render.py
Outdated

I do not think that calibration.cpp copy-paste from main repo is required. Could we just reuse it?

It should be an option, I believe.

The CMakeLists.txt proposes calibration_benchmark name for executable

What is difference between the code in PR and example in OpenCV. I propose to not add copy, but add reference to OpenCV itself. Also interactive calibration tool is always build with OpenCV and provided in distribution. It could be a replacement.

I propose to have #ifdef with OpenCV version here to have proper includes according to OpenCV version. I do not see 5.x specific code here.
