Change Description

Description of Change

CV is switching to a global shutter camera, rather than the Raspberry Pi Camera v2 which uses rolling shutter. Specifically, this camera: https://hupuu.com/camera/1080p-2mp-global-shutter-color-usb-camera-module-yuy2-usb2.0-100fps-mjpeg (TODO: Lens selection pending)

Implementation

The camera is connected to the Jetson via USB cable. Camera side: 4-pin connector. Jetson side: USB-A.

Possible implementations:

• Camera mounted on frame fuselage interior, with tip of lens flush or sticking out a hole.

  • Requires drilling <20 mm diameter hole in frame.

• Camera mounted on frame fuselage exterior, covered by aerodynamic shroud.

  • Unaerodynamic due to camera height, but that won’t really matter if it is possible to mount on the aft of the fuselage.

Reason for Change

The GoPro Hero 7 footage looks terrible, which is most likely caused by its rolling shutter. The Raspberry Pi Camera v2 also uses rolling shutter, so it is not suitable to use.

Priority

⬆️ High

Impact of Not Responding to Change

CV will have suboptimal footage, which may make landing pad detection impossible.

Alternative solutions:

• Physical stabilization of drone and/or camera (hard).

• Software correction (very hard).

Change Impact

Additional Parts/Resources Required and Costs

New camera needs to be purchased and mounted on the frame.

Impact on deadlines

CV doesn’t have a working airside system until this is done. Also, CV probably wants to train on footage from this camera. RIP adding more work for mechanical subteam as well.
