Hi, I am building a full body scanner, and needed small cameras. I have used raspberry pi V1 5mp cameras. But as i need about 100 cameras and the v1 model is discontinued i would like to change those cameras with Arducams 5 mp. My target is to make as sharp as possible picture of size about 40 cm* 40 cm from distance of about 130 cm. Which model of Arducam would be the best for that goal? Thank you.
Hi kazerog,
What will be connected to those 100 cameras ?
This is a massive amount of video processing, usually people use fewer camera and either turn around the person or make the person turn.
Note: We also have the V2 Pi camera HERE
Hi Eric,
V2 is of poorer quality then V1. The color of V2 are better, but sharpness is not. So i think of swithcing form pi cameras to arducams and increase the quallity of the picture with lenses. Need to know which arducams and which lenses would be better for that project.
Again, what would be connected to the cameras ?
Raspberri Pi 3 B
You will be using some kind of multiplexing devices for the cameras ?
It’s not possible to connect that many cameras on the Pi.
The V1 camera use a “OV5647” sensor (info) and there are a bunch of other cameras using the same sensor HERE.
They should give you similar results… 
Each camera is connected to one board. There is as many boards as the cameras are.
Let me ask you following:
- OV5647 is Rev.C OV5647 Camera for Raspberry Pi Improves the Optical Performance?
- What lens is coming with OV5647 M12?
- What lens is comming with OV5647 cs mount?
- What lens would be better for my application (distance to object 130-140 cm, each camera will shoot 40*40 cm)?
- The mount (m12, c, cs) has nothing to do with a camera, it is only for different types of lenses. Is it right?
- Which is better OV5647 or OV5642? Better i mean sharper and color more realistic.
- Can i buy camera and choose what lens will be placed on it?
I frankly would like not similar results, but better. Kindly advise me on camera and lens
Thank you.
Any success or news?
I’m interested in your project.
Also, in case it helps, I have a related project (but much simpler) and new thread about the ArduCam multi-camera adapter + ArduCam “spy camera” (OV5647) + RPi 3. The adapter boards can be stacked to support 16 cameras per RPi but power/voltage on each unit is potentially a deal-breaker. Also, only 1 of the cameras per RPi can be active at any one instant. But for 100 cameras, non-moving subject, it might help logistically.
FWIW a couple of other things
]Your question (4) about which camera/lens combo makes the sharpest image can be tricky. I don’t often see f-number listed in robot vision cameras. But even if it is poor, maybe you can control illumination of your subject (ambient light level) to help. Wikipedia of “f-number” might be a useful starting point; usually there is an optimal ratio of aperture to working distance for a given lens. Also there are quite a few aberration / distortion correction routines in OpenCV, but I’ve had issues getting them to work at full resolution. /:m]
]question 5, mounts/etc, you are correct. But perhaps there’s another way to evaluate that also answers number 4. . Market size/demand seemingly plays a role. If the sensor is weak (but cheap) it has little need for a big lens, so the mount is small (and cheap). When there are more mounts to choose from, it’s evidence that the sensor is more capable./:m]good luck
