CV Education for the 2018 season

OpenCV needs to be installed at lib/opencv-3.2.0.

On Linux, you can install OpenCV with the install-opencv-unix.sh script. There are more detailed instructions on this in the README of github.com/Team694/stuyvision-lib. Once CV is setup, run make to compile and then make run to run the project. To set up on Windows, see windows-setup.md for instructions.

Reference

• ReadTheDocs tutorials for OpenCV with Java (and GUIs with JavaFX).

• Official OpenCV 3.1.0 JavaDocs. (There are no JavaDocs for OpenCV 3.2.0.)

• Official OpenCV 3.2.0 documentation. This has much more detail than the JavaDocs, but is intended for those using OpenCV with C++. There are no examples in Java (all are C/C++).

More resources here, in stuyvision-lib.

Note:

If you're working on your own laptop and you have an installation of OpenCV 3.2.0 elsewhere on your laptop, you don't need to install it again. Instead, create a symbolic link with this command:

$ ln -s /path/to/OpenCV-3.2.0/installation lib/opencv-3.2.0

You may also do the same with your jfxrt.jar (which should be installed at /usr/lib/jvm/default-java/jre/lib/ext/jfxrt.jar if you are running Ubuntu.)

$ ln -s /path/to/jfxrt.jar lib/jfxrt.jar

Working on the school desktops

To develop on the desktops, log in to either a Guest session or your own account, then clone this repo and set up your environment:

$ git clone https://github.com/Team694/cv-edu-2018
$ cd cv-edu-2018
$ source setup-workstation.sh

As usual, use make to build:

$ make
# code compiles
$ make run
# code runs. Ctrl-C to interrupt (like force quit)

If you encounter an error while running make run similar to the one below:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /path/to/cv-edu-2018/lib/opencv-3.2.0/build/lib/libopencv_java300.so: libopencv_photo.so.3.0: cannot open shared object file: No such file or directory

you may need to run the command:

$ export LD_LIBRARY_PATH=/path/to/cv-edu-2018/lib/opencv-3.2.0/build/lib/
