Save Labeled Images

Version Note

This tutorial was originally created for an earlier version of Brobot but has been updated for version 1.1.0. The original code examples are available in documentation versions 1.0.6 and 1.0.7.

The SaveLabeledImages Class

In the main program loop, we first go to the Island state. If this fails we exit the program, to keep things simple. Normally you would want Brobot to find out where it is and either make its way back to the target state or do something else.

We then loop for the number of images we wish to save, get a new island type, and save it to file.

@Component
public class SaveLabeledImages {
    
    private StateTransitionsManagement stateTransitionsManagement;
    private ImageUtils imageUtils;
    private GetNewIsland getNewIsland;
    private IslandRegion islandRegion;
    
    public SaveLabeledImages(StateTransitionsManagement stateTransitionsManagement,
                             ImageUtils imageUtils, GetNewIsland getNewIsland,
                             IslandRegion islandRegion) {
        this.stateTransitionsManagement = stateTransitionsManagement;
        this.imageUtils = imageUtils;
        this.getNewIsland = getNewIsland;
        this.islandRegion = islandRegion;
    }
    
    public void saveImages(int maxImages) {
        String directory = "labeledImages/";
        if (!stateTransitionsManagement.openState(ISLAND)) return;
        for (int i=0; i<maxImages; i++) {
            String newIslandType = getNewIsland.getIsland();
            Report.println("text = "+newIslandType);
            if (!newIslandType.isEmpty() && islandRegion.defined()) {
                imageUtils.saveRegionToFile(islandRegion.getRegion(), directory + newIslandType);
            }
            Report.println();
        }
    }
}

Run 'saveImages' from the Executable Class

After the code to initialize the beginning active states, add the following code. This will save a maximum of 100 images.

// get and save labeled images
SaveLabeledImages saveLabeledImages = context.getBean(SaveLabeledImages.class);
saveLabeledImages.saveImages(100);

That's it! Now your demo application should be ready to go. Run it to see the mock output in your console.
