Warning! This functionality is in test mode. To use it you need to install a test version of the firmware. We will be glad to get your feedback and suggestions about this functionality. Write to support with a note "Test of working with images in TRIK Studio".
Developing the algorithm under unchanged conditions allows to debug and test it faster, as well as to evaluate and compare the quality of the algorithm and its modifications. This is especially important for computer vision algorithms, when any, even small, camera movement significantly changes the shooting conditions and, as a result, the captured image.
This article will describe how to capture images on the TRIK controller camera, upload this data to a computer and use it in TRIK Studio to develop and debug computer vision algorithms.
ARTag 5x5 datasets
ARTag marker recognition programs can be improved and tested in TRIK Studio on the dataset (see step 3). It includes photos of ARTag 5x5 markers from different angles on a standard TRIK controller camera. The name of each folder in the dataset is the number that is encoded on the ARTag markers that lie in that folder.
Warning! Connect the camera to the "video2" port before turning on the controller.
1. From the controller menu, selectTesting → Camera
.
2. The image taken by the camera will be displayed on the screen. It will be saved to the internal memory of the controller.
To take more photos, press the "Exit" (cross) button on the controller and select the Camera
menu item again.
1. Connect the TRIK controller to the computer.
2. Enter the IP address of the controller in the address bar of your browser. The TRIK web interface opens.
3. Go to the "Images" tab and click "Download all" to download the image archive.
4. Go to the folder with the downloaded archive and unzip it. Now you can select the images that are best suited for developing and testing the current algorithm.
1. Open the Robot settings in TRIK Studio.
2. In the window that opens, select Robot Model → 2D Model
and type in the path to the previously loaded images.
3. Now when you call getPhoto, the images from the specified folder will be loaded sequentially.
An example of a program that sequentially displays images loaded from a specified folder with a 2-second delay.
1. Download the file to your computer or create a new project and copy the code:
2. Run the code in debug mode, using the 2D model as the program execution mode. The controller will display images sequentially on the display.
