I am new in raspberry pi and all the hardware stuff and experienced a bit in java. I have a project which I need to complete pretty soon.

For it, I need to run multiple cameras to cover all four sides and one for up. That means a minimum of 2 cameras. After it, I need to detect objects using TensorFlow Lite which I know how to do in python and relatively low FPS like 4 FPS is acceptable but not below that. and then I need to get the distance of the detected object from the camera.

It is complex to read I think and a lot for me to do. Please guide me into what should I use for this and is Raspberry Pi fine for it. Please also tell me which module and Pi should I buy.

Edit: Overall, what I want to do is detect objects and get the depth map of the detected object. The detected object will be detected by a custom TensorFlow Lite model. Then I need to figure out how far that object is and do some more processing on the distance value. It should be around 4 - 5 FPS minimum. I don't need to show the recording. The problem is that raspberry pi has only 1 camera port but I need to use at least 2. Please Help

Thank You, with Regards.

  • I will try adding more information – Demon App Programmer Jan 11 '20 at 14:24
  • Please check the question again. I have added more explanation and figured out I need at least 2, not 3. – Demon App Programmer Jan 11 '20 at 14:37

The thing that you are going to do is really interesting for me. However, you are right. The Raspberry Pi has only one camera port. It means that you are able to plug only one camera module. Although, you can connect any normal USB camera to this board.

fosa USB Camera for Raspberry Pi can be a good option for you. It needs no driver and it's easy to use if you want to plug it on a Raspberry Pi.

    The problem has not gone yet. Can you guide to an alternate board like RPi or some driver? I think that if I use Arduino to use the cameras and then transfer data to the RPi. Is it practical? – Demon App Programmer Jan 11 '20 at 14:51

    You can attach both cameras to a single board like Raspberry Pi. So, why do you need an alternate board? I didn't get it. – M. Rostami Jan 11 '20 at 14:55

    That is the question that how can I attach both cameras to a single board. Maybe I didn't clarify the question properly – Demon App Programmer Jan 11 '20 at 15:11

    You mean, in software sight? In the hardware sight, it's not complicated. – M. Rostami Jan 11 '20 at 15:12

    Yes actually if I can plug in the USB cameras but how can I use both cameras simultaneously – Demon App Programmer Jan 11 '20 at 15:14

Actually you can use a StereoPi board, as it allows you to connect two cameras at once. This board is based on the Raspberry Pi Compute Module 3, so you can work with it as with a classic Raspberry Pi (and use stock Raspbian). I'm one of the developers of this board, so will be glad to help you with all I know.

Your idea of using Tensor Flow light is very interesting!
