OV9732 Camera Bracket

🎯 OV9732 Camera Mount for Target Corona Light Ring (DartScoreCounter / AutoDarts)

This is a custom-designed camera mount for computer-vision-based automatic dart scoring systems.

This bracket securely clips a standard OV9732 USB Camera Module directly onto a Target Corona Vision Light Ring, providing the ideal angle and lighting for dart tracking — without damaging the light ring.

🛠 What Is Included

• Camera Bracket

The main housing that snaps onto the light ring and holds the camera lens/PCB.

• Backplate

The rear cover that sandwiches the camera PCB securely into place.

Note: Most camera-based scoring systems use three cameras spaced evenly around the ring to triangulate dart impacts.

------------------------------------------------------------

🔩 Required Hardware (Bill of Materials)

To assemble one camera mount, you will need:

• 4x M2x8 mm screws

• 4x M2 hex nuts

If you are building a full 3-camera setup, you will need 12 screws and 12 nuts in total.

------------------------------------------------------------

🔧 Assembly Instructions

1. Insert the 4 M2 hex nuts into the printed PCB stands inside the main camera bracket.

2. Seat the OV9732 camera module into the bracket so the lens pokes through the front opening.

3. Place the backplate over the rear of the camera PCB.

4. Insert the 4 M2x8 mm screws through the backplate, pass them through the mounting holes on the camera PCB, and tighten them into the hex nuts in the bracket stands.

5. Clip the assembled unit onto your Target Corona Light Ring.

📐 Setup Advice for AutoDarts & Custom Systems

For a 3-camera triangulation setup, mount the three cameras exactly 120 degrees apart along the light ring.

This ensures:

• Optimal coverage of the dartboard

• Reduced blind spots

• Better dart detection accuracy
