Orientation - how the shape would have to be rotated to match the closest match To the best available match in the database of trained shapes. Will show the match information about each object in the main RoboRealm image window.Ĭonfidence - how well the shape matches those in the database. To get a sense of what you can use to filter out objects click on the Display checkboxes which Depending on your matches you may want to filter out specific objects.

NOTE: the shape matching only works onīinary black and white images with the object being in white and the backgroundģ. Click on '.' to select the folder where the images you would When new images are added or old ones deletectedĢ. This folder becomes the 'training' database. Image from the camera, take a snapshot of that image, threshold to black and white (white being active signal) and save Training images should be located in a specified folder. Press the 'Train' button to create a new image database. Given perspective distortion which would proide some stability. Alternatively, you can snap many images of the shape Perspective module to adjust the image such that the shape appears as if theĬamera was looking right down on the shape. Thus if your shape is on the floor with yourĬamera pointing outwards, you will probably not get very good matches. The module does NOT adapt to changes in perspective.
Using this database of images, new images fed in from the camera (after being thresholded) will beĬompared to the known database with resulting similarity being displayed. (White being the shape, black being the background).
It expects to see black and white images in thatįolder that are processed for shape information. The module uses a specified folder for training. In this way the matches are invariant to shape translation, size Is based on actual image shape and NOT on direct pixel matching as done Object and that stored in the image database.
