DLPDLCR2000EVM: Camera Compatibility

Part Number: DLPDLCR2000EVM
Other Parts Discussed in Thread: DSLR, DLP2000

Greetings experts!

I would like to know which cameras are compatible with DLPDLCR2000EVM. Will a normal webcam or DSLR camera work fine or is it only compatible with a point grey camera.

Regards

    Hello Sheharyar,

    Could you please elaborate what you plan to do with a camera? The DLPDLCR2000EVM is a projector that is mounted onto a Beaglebone Black. While you could connect a camera to the Beaglebone Black for use in your own application, you will not be able to directly attach the camera to the DLPDLCR2000EVM.

    Thanks,
    Kyle

    Dear Kyle,
    Thank you for your response. I intend to use DLPDLCR2000EVM in my application for DLP scanning. I intend to interface a camera with this DLP chip but I am confused regarding the fact that which camera type will be supported by this chip. I currently have a Prosilica GE 1910 HD Resolution CCD camera with GigE Vision interface and would like to know if this camera will work fine with the DLPDLCR2000EVM.

    Hello Sheharyar,

    Are you planning on creating your own 3D scanning application? You will be able to use whatever camera you desire for your application as it will not directly interface with the DLPDLCR200EVM. The DLP2000 EVM will simply project the desired image. You can capture the image with the camera and send it to the front end processor where your scanning code is being run (it could be a PC or the Beagle Bone Black). The DLP2000 EVM itself does not do the image processing from the camera. We do have some reference code for image projection and camera synchronization; however, this does not handle connecting to the camera itself. Let me know if that makes sense.

    Thanks,
    Kyle

    Dear Kyle,
    Thank you for your generous responses. Could you please tell what interface would the camera use to connect to the PC, either USB or some other connection type.

    Hello Sheharyar,

    It depends what camera you select. It could be USB, Ethernet, etc. This would be independent of the DLP200 EVM. If you detail how you are trying to use the EVM perhaps I could better help.

    Thanks,
    Kyle

    Dear Kyle,
    I am trying to develop a 3d scanner using DLP 2000 EVM. The built in projector will be used to project the image and an external camera will be used to take images of this projection. The images will then be used to develop a 3d scan. I would like to know that if I buy the DLP 2000 EVM and use the camera Prosilica GE 1910, would I be able to generate a 3d scan for my application or would I need to use a global shutter camera for this application.
    Thanks,
    Sheharyar.

    Hello Sheharyar,

    You will have to decide what camera you would like to use depending on your system requirements. As TI does not have a 3D scanning reference design for this DMD we have not tested the DLP2000 with various cameras.

    However, in general I would expect you will want a camera with at least 2x the resolution (the DLP2000 DMD is nHD which is 640x360). A global shutter is generally only needed if you are doing very fast framerates which the DLP2000 does not generally support. Like I said before though, the camera design will be your choice and TI does not have specific requirements. 

    You may be interested in this reference code though  It will provide triggers to help synchronize a camera that accepts external trigger inputs. It also enables you to use the Beaglebone Black to control various pattern projections. 

    Thanks,

    Kyle
