For a personal project I plan on using a triple camera setup. So, I was searching about multiple cameras on the Vim 3 but I found nothing. So, I open this topic to ask if it’s possible to have 3 cameras on this computer somehow ? The specs say the Vim 3 supports dual cameras. Does this mean you can only have 2 cameras total (USB + one on the MIPI-CSI interface) or does it mean that the MIPI-CSI interface can handle 2 cameras ? I would be very happy to have more informations about that because this SBC is perfect for my project. Thank you in advance.
Below is the spec of the A311D 8MP HDR ISP:
- Single pixel per clock architecture with 600 Mpixel throughout
- Multi Camera, Multi Exposure
- Support up to 2 cameras, up to 8M pixel sensors, up to 60fps
- 1 x 8Mpix x 60fps, or 1 x 8Mpix x 30fps x 2exp
- 2 x 4Mpix x 60fps, or 2 x 8Mpix x 30fps
Regarding the triple cameras, I still have to confirm again, and I will update here.
First thanks for responding this fast !
Is it possible to have 2 cameras on the MIPI-CSI interface (via an adapter) ?
Actually, extra adapter is not required, as the MIPI-CSI connector with two clocks and can works as two mode:
- Clock A + 4 lanes
- Clock A + 2 lanes & Clock B + 2 lanes
BTW, may I know that why you need 3 cameras?
Yeah sure, I’m building an autonomous lawnmower for my mother. So I need 2 extra cameras to detect obstacles and borders to the side of the robot (1 front camera and 2 side cameras).
How do I implement this double camera setup physically ? Do you know any tutorial on how to do that ?
I want to connect two rasperryi cam , maybe 8mp or 5 MP .how can I connect two camera on the mipi-csi to vim3
You can’t connect 2 rasberry pi cameras at the same because the CPU can only handle 8 megapixel total and those cameras are 5 MP or 8MP. But If you have two 4MP (or less) similar to the rasberry pi then you can do it. Now, how do you physically do it I don’t know, I don’t understand the schematic that the staff gave above well enough to tell you. That’s actually what I want and understand to know too.
Is there a list somewhere of compatible MIPI-CSI cameras that can be used on the VIM3? I tried a couple now and neither worked, leading to the VIM3 not even turning on anymore while connected. A list of compatible cameras would help a lot here.
Currently, A311D only support below sensors, it will take some time to add more sensors:
Can you give some examples of ready-to-use modules? (e.g. links to aliexpress or something)
I’m having a really hard time to find a MIPI-CSI module that fits the VIM3’s 30 pin connector, especially with the sensors that you listed above. The IMX290 seems to mostly only exist as USB module, the IMX307 I can barely find and the IMX415 doesn’t seem to exist as “breakout” at all. As for the OS08A10 I can only find modules (e.g. https://www.aliexpress.com/item/32864848633.html ) that are less than 20 pin, hence won’t fit the VIM3.
Maybe Khadas could provide a list of tested & compatible, ready to use modules on their site? After all they’re marketing the VIM3 as dual-camera MIPI-CSI capable, which for me was the reason to buy it in first place.
Yes, you cannot find a existing camera module for VIM3 as the pinout is not a standard.
We will build a camera module for VIM3, but it will take a few weeks for delivering.
Where and when will we be able to get this camera module ?
will you provide m12 lens with the sensor ?
We tend to use the CS mount lens with sensor for Surveillance applications, some one like this:
PS: my hand is not as famous as @tsangyoujun one
Oh yeah that would work too!
Any ETA ?
Hello, is it possible working with two USB cameras ?
Amlogic series seems to support only one USB camera despite I have a edge but its too hot to work for 4K analytics.
Give it a little time.
- Sensor: OS08A10
- CS Mount
- Aperture: F2.0
- HFOV: ~150
- IR CUT
- Dimensions: 40x40x47MM
Can a smaller lens be used? I don’t have that much space where I would like to use the Khadas cameras.
