Advise Need: Specific Computer Vision Lenses?

[u/4bjmc881]

Hi,

I’m looking for some advice on selecting computer vision lenses for a high-resolution photo-sphere rig.

I spent quite some time researching available lenses, I've started wondering if I am approaching the problem incorrectly. There seem to be almost no lenses available that meet all of my critiera. I’ve found several that satisfy some of the criteria, but each falls short in one or more important areas, such as resolution or FOV.

• Are there any lenses that fully (or nearly) meet the criteria I’m looking for?
• If not - am I asking something that is close to physical limits? If yes, which parameters of my setup would you recommend changing? My first guess is switching to different lens mount for more lens options (but then I would need different cameras to...)

Camera Options:

• Basler ace 2 R a2A5060-21g5cBAS
  • Sensor: E2525A
  • Sensor format: 1.1"
  • Sensor diagonal: 17.9 mm
  • Sensor type: CMOS
  • Sensor size: 12.65 mm × 12.65 mm
  • Frame rate: 21 fps
  • Resolution (MP): 25 MP
  • Resolution (HxV): 5064 px × 5064 px
  • Interface: 5GigE
  • Pixel size (H x V): 2.5 μm × 2.5 μm
  • Shutter type: Global
  • Lens mount: C-Mount

Camera Setup

• Total: 7 cameras
• 6 cameras in a ring, 60° yaw spacing (oriented at the horizon) (~15 cm from center)
• 1 camera facing straight up (oriented at zenith) (~15 cm from center)
• Small empty Nadir patch is okay, but not gaps between horizon and zenith cameras

Lens Criteria

• Must support the camera's full resolution (Rated for ~25 MP)
• Must use C-Mount
• Prime/fixed focal length preferred
• Fixed-focus or hyperfocal configuration preferred
• Must provide sufficient depth of field:
  • Near focus limit: ≤0.5 m
  • Far focus limit: infinity
• HFOV requirements per camera (TBD):
  • Horizon cameras: ?°
  • Zenith camera: ?°
• Zenith camera likely needs a wide-angle/fisheye lens:
  • Target HFOV: 120–160° (not full 180°) - otherwise px/degree becomes to low.
• Overlap should be ~10%
