Calibration-Use-ChArucoBoard

Base on Opencv3 and Aruco, Use in Qt.

With 3 Cpps

  • main.cpp is Calibration main Cpp
  • drawcharucoboard.cpp as the name, generate the ChArucoBoard
  • testvideocapture.cpp test the video file is Recognized by Opencv3
  • mutexvideocapture.cpp base on testvideocapture.cpp, but let VideoCapture.read() run in another thread, which can increase the video FPS. reference: increasing-webcam-fps-with-python-and-opencv

you can modify the Calibration.pro to Build and Run.

References:

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 += .
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

TEMPLATE = app

SOURCES += \
    drawcharucoboard.cpp

DEFINES += QT_DEPRECATED_WARNINGS

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
