An opencv application for detecting and recognizing different shapes of various colors
This program uses the cmake to compile and requires a C++ compiler and the OpenCV library to be installed to be able to compile correctly.
Note: This program was developed for the linux operating system and thus has not been tested for differing operating systems
To compile do the following:
Create a new directory for the build files and enter it.
mkdir build && cd build
Call cmake to configure the project.
If this command returns errors, recheck that you installed the C++ compiler and the OpenCV library correctly.
cmake ..
If cmake has succesfully configured the project you will be able to build the project by doing the following
make -j4
To run the program execute the following command in a terminal:
./recognize -i [path to image file]
To recognize shapes in an image.
Or
./recognize -c
to use the default webcam feed for recognizing shapes.
After you have done this without any other option you will be greeted by a command prompt that looks like this:
input>
Here you can enter a combination of a color and a shape. The following colors are available:
- yellow
- orange
- green
- pink
Which should be followed up by one of the following shapes:
- square
- rectangle
- circle
- half-circle
Then once enter is pressed a window will show the shape of that particular color being recognized
You can use the -f option to load a text file containing a series of commands.
These scripts may also contains line with a #, all charachter after this will be ignored (for comments and such).
You must press a button while focused on the window to advance through the script but you can also use the -d option to set a delay in milliseconds after which the command interpreter will continue with the next line in the file.
