As I understood from your previous answers, your suggestion was to check for arducam camera with M12 mount and something like the 2.3mm lens that will give me about 86 deg HFOV fully illuminated chip.
The camera that I’m asking before is Arducam camera with Sensor: IMX477, Optical Size: 1/2.3″, Field of View: 96° – 33° (Horizontal), Platform Support: Raspberry Pi/Jetson Nano/Xavier NX. As I see this is almost the same camera as that you suggested before. What is the cause of your concerns?
May be this is one of the reasons, written on the site of Arducam manufacturer:
Our IMX477 camera module support 4-lane in hardware, but the 4-lane camera driver requires extra customization. Here is why:
Standard Raspberry Pi can’t physically support a 4-lane connection (only have 2-lane CSI connectors).
But you can see from the movie on Arducam website that this camera is connected to the Raspberry board.
I only want to state that I have not qualified that camera. It may be fine, I don’t know.
That is all. I am not arguing that the one you point out will not work.
The arducam that I I pointed out before has a rather old camera by todays standard, I simply was indicating ones I have worked with to date with success.
In the world of software and drivers ‘almost the same’ does not mean exactly the same.
It’s a great chip on the one you are indicating and I may look into it in the future, just too busy on other things to dive in but would be very pleased if you report back here to this forum when you have success with any camera. This forum is for users to share experiences and findings of new devices that work out nicely with our image and robot.
Thanks for the report, Mark
Looking a little at that Arducam Mini using Imx477 note that it is using the same chip as the RaspiCamHQ. Your lens choice is important. This chip is very big so a tiny M12 lens may not illuminate the entire chip. Look at the in-focus illuminated field info for the lens you choose. Ideally lighting the full chip avoids things like the 4 corners of the image area are black or extremely dark which limits your field due to image clip.
So my guess is because the RaspiCamHQ works on the Pi and they are saying it works on the Pi it likely is a camera that will work. The issues become how much of the frame you can see with such a large chip and a M12 lens and still keep the fisheye effect not so severe that the image is warped too much to correct properly.
Thank you for your reply. Could you please check these two camera modules too:
Motorized Focus: B0272
HQ camera: B0262
I would like to purchase one camera that could extend my field of view for sure and one that will be used for experiments ( https://www.uctronics.com/camera-modules/camera-for-raspberry-pi/arducam-imx477-12mp-ptz-camera-for-raspberry-pi-4-3b-3-and-jetson-nano-xavier-nx-ir-cut-switchable-camera-with-metal-base-and-2-digital-servos-b0167b12.html )
What is your opinion? Thank you!
