Setup Controls
- David Avgikos
The Setup Control Panel contains controls for calibrating DART MAX. This is the process of aligning the camera and the projected image for accurate shot tracking. Once the system is calibrated, it does not need to be calibrated again unless the camera or projector moves. You can find more information on the calibration process here.
Camera Position
In most cases, the camera will be positioned on the floor, however in cases where the camera is mounted to the ceiling, the Camera Position control should be used to rotate the image.
Camera Gain
This control is reserved for future expansion and is inactive at this time.
Image Brightness
The Image Brightness slider adjusts the exposure setting of the shot detection camera. Higher values let in more light and lower values let in less light. In most cases, this setting should be between 20-50%. You can find more information about Image Brightness in the calibration section.
Camera Threshold
Camera Threshold is similar to a contrast setting that dark and light objects. As a general rule of thumb, the brighter your room is, the higher threshold setting you will need. In most cases, this setting should be between 80-150. You can find more information about Camera Threshold in the Calibration section.
Area of Interest
The camera will capture information outside the projected image, including walls, windows, doorways, ceiling lights, etc. - all of which could compromise calibration. The Area of Interest sets a boundary for the camera so that it does not process anything outside the screen area.
When the Area of Interest control is On, you will see a green box with eight adjustment handles similar to the image below. Using the mouse, move these handles until the area of interest is defined, as shown below. Ensure there is space between the projected image and the Area of Interest box.
Grid Size
The system will project a grid of dots on the screen to calculate screen size and camera distortion. There are two options, 8x8 and 16x16. In virtually all cases, you should use the 8x8 option. Some ceiling mount systems in which the camera is positioned 10 feet away from the screen should use a setting of 16x16.
Run Calibration
Once the grid size has been set, you are ready to calibrate. Click the Run Calibration control to initiate the process.
The computer will change the display as needed and when the process is complete, it will engage the IR cutoff filter inside the OptiTrack camera.
The title of the control will change based on the state of calibration.
Calibrated if the calibration process has been successfully run.
Not Calibrated if there is no calibration information stored or calibration was unsuccessful.
Working if the calibration process is running.
