Camera Calibration Use Charucoboard

The camera, which last use, imaging effect is not very good. So bought a new one, Which support 720p video with 30FPS and more, use this opportunity, talk about use chArucoBoard to calibrate the camera.


Calibration with ArUco and ChArUco

1. Generate ChArucoBoard

From the reference, can get Source code from here

Because with Qt, the Qt Pro file is:

QT += core
QT -= gui

CONFIG += c++11

TARGET = new_camera_Calibration
CONFIG += console
CONFIG -= app_bundle
INCLUDEPATH += /usr/local/include/

LIBS += -L/usr/local/lib/ -I/usr/local/include -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_aruco -lopencv_imgcodecs -lopencv_calib3d -lopencv_videoio




and with Qt Creator 4.2, in the left side, choose Project->Run Setting-> Command line arguments, input this:

-w=7 -h=5 -sl=80 -ml=70 -d=11 -bb=1 -si=true /home/nimo/NewCamera/Temp/0601.png

Then, run the source code, you can get a Board.

2. Calibrate

And then, you can use your camera to take a video, the content is the ChArucoBoard what is generate in first part.

Use Python Code to Get avi, I dont know the reason why the Opencv3 could not recognize the video which I get from AMCap. And then, use the Source Code here

and here is the Args:

-w=7 -h=5 -sl=80 -ml=70 -d=11 -sc=true -v=/home/nimo/Videos/NewCamera/calibration.avi /home/nimo/NewCamera/Calibration.txt

Of course, here is my Project in github : here
