Luxonis Proprietary 48MP Camera Module

This is a proprietary 48MP (8000x6000) rolling shutter color image sensor. It’s the highest resolution sensor that depthai currnetly supports.

THE_12_MP

4000x3000

Full FOV, super-pixel / quad-bayer binning

THE_4_K

THE_48_MP

Full resolution, currently width is cropped

Currently full resolution (THE_48_MP) is center cropped to 5312x6000 (due to current ISP width limit). We are working on implementing split processing for the full 8000 width. So at the moment the image at full resolution (THE_48_MP) has narrower HFOV than the camera actually is (see image below), just because of this limitation on linewidth.

To use the LCM48, checkout depthai-python to the multi_cam_support branch, and install the library by running python3 examples/install_requirements.py. You can quikcly evaluate the sensor by running python3 tests/cam_test.py -cams rgb,c -cres 48mp.

FFC compatibility

With OAK FFC boards you can easily evaluate different sensors and optics, as you can connect FFC camera boards to any OAK FFC baseboard (OAK-FFC-4P, OAK-FFC-3P) via a flexible cable. FFC camera boards are carrier boards for the CCM (additional information below), so it can easily be connected to any OAK FFC baseboard. The following FFC camera boards contain this sensor:

  • OAK-FFC-LCM48

Sensor CCMs

Compact camera modules (CCMs) can be integrated directly into a custom product. CCMs are used in the final camera product. CCMs vary in optics and FPC connector. The following CCMs have been built using this sensor:

  • Arducam short FPC:

    • NFOV - 82° DFOV, 68° HFOV, 55° VFOV, EFL: 4.74, F. NO: 1.79±5%, Distortion: < 1.5%, Lens Size: 1/2”

      • AF: PY080

      • AF NoIR: PY101

      • AF IR notch filter (IR650+940): PY102

      • FF: PY106 (Focus: 50cm+)

    • WFOV FF (PY080) - 120° DFOV, 96° HFOV, 89° VFOV, EFL: 2.75, F. NO: 2.8±5%, Distortion: < -14.6%, Lens Size: 1/2”, Focus: 50cm+

Image quality comparison

Here’s an image comparison between different image sensors captured from OAK-FFC-3P. For more information, see Improving Image Quality docs.

Click on the image for the unencoded full-resolution sensor comparison image. Note that these images are about 8x digitally zoomed, and you can find full-resolution uncropped frames here (300 MB). Image specifications: Grocery items are at 4m, 33LUX, senstivity 100ISO. Images were taken at 200ms,300ms,400ms,500ms exposure and combined with an HDR script (on the host). OAK Series 3 cameras will have native HDR support on the camera itself.
