Objects recognition
We have used the package find_object_2d which has been develop by Mathieu Labbé (Université de Sherbrooke). The program can recognizes objects in the scene using an image of the object. The program has a graphical user interface which allow to capture an image of the scene and save it.
Screenshot find_object_2d
In the screenshot that is shown above, we can see how the recognized object is within a boundary box which coincide with the corners of the object image.
The program provides several data of each found object in the scene. We will use the next data:
- Width of the object image (number of pixels).
- Height of the object image (number of pixels).
- Position of the corners of the object image in the scene.
