Flea3 USB3 camera and camera1394 package

I have been working with Firewire cameras on my Mac using camera1394 package. Now I decided to switch to Point Grey Flea3 USB3 cameras. I remember a year ago I have read that these cameras support IIDC and that time I was able to capture images from these cameras using libdc1394 (without ROS). Now I am struggling running it with ROS camera1394 package. My questions,

(a) Did somebody use these cameras with libdc1394, without Flycapture (maybe in Linux, better in OSX)?

(b) I cannot find Flea3 GUID, that camera1394 requires. Do USB3 cameras have GUIDs?

We are using Chameleon, has GUID and works, but that is USB2. I had to make an udev rule to add it to plugdev group.

Thanks for reply, I managed to make it run on OSX. There are still some things that I am not happy with, such as delay. Will test everything then write the answer.

I also got a Chameleon Point Gray camera to work in OS X via libdc1394. The problem is that I can't figure out how to set the camera mode for it to give me color in OpenCV.

The solution was to rebuild libdc1394 library. Here is what I did,

1) downloaded latest version of the library, libdc1394-2.2.

2) added vendors and products codes to usb_products[] that is defined in libdc1394-2.2/dc1394/usb/control.c For flea 3, I added these two lines { 0x1e10, 0x3000 }, { 0X1e10, 0x3006 }, Finally the structure looks as follows

/* This is the list of USB vendor/products that we know support
 * IIDC-over-USB.  Currently, this is the only mechanism of detecting
 * such cameras. */
static struct _vendor_product_t {
    uint16_t vendor;
    uint16_t product;
} usb_products[] = {
    { 0x1e10, 0x2000 }, // Point Grey Firefly MV Color
    { 0x1e10, 0x2001 }, // Point Grey Firefly MV Mono
    { 0x1e10, 0x2002 }, // Point Grey High Res Firefly MV Color
    { 0x1e10, 0x2003 }, // Point Grey High Res Firefly MV Mono
    { 0x1e10, 0x2004 }, // Point Grey Chameleon Color
    { 0x1e10, 0x2005 }, // Point Grey Chameleon Mono
    { 0x1e10, 0x3000 }, // Point Grey Flea 3
    { 0X1e10, 0x3006 }, // Point Grey Flea 3 Color
    { 0, 0 },
};

3) Rebuild libdc

4) Build and run the following code that will allow you to get GUID. Later this GUID should be put to camera yaml file to run camera1394.

#include <stdio.h>
#include <stdint.h>
#include <dc1394/dc1394.h>
#include <stdlib.h>
#include <inttypes.h>

int main(int argc, char *argv[])
{
    FILE* imagefile;
    dc1394camera_t *camera;
    unsigned int width, height;
    dc1394video_frame_t *frame=NULL;
    //dc1394featureset_t features;
    dc1394_t * d;
    dc1394camera_list_t * list;
    dc1394error_t err;

    d = dc1394_new ();
    if (!d)
        return 1;
    err=dc1394_camera_enumerate (d, &list);
    DC1394_ERR_RTN(err,"Failed to enumerate cameras");

    if (list->num == 0) {
        dc1394_log_error("No cameras found");
        return 1;
    }

    camera = dc1394_camera_new (d, list->ids[0].guid);
    if (!camera) {
        dc1394_log_error("Failed to initialize camera with guid %llx", list->ids[0].guid);
        return 1;
    }
    dc1394_camera_free_list (list);

    printf("Using camera with GUID %" PRIx64"\n", camera->guid);

   dc1394_video_set_transmission(camera, DC1394_OFF);
   dc1394_capture_stop(camera);
   dc1394_camera_free(camera);
   dc1394_free (d);
   return 0;
}

It is useable now, although there are some issues with setting different modes and reducing the delay. I don't have these issues on a Windows virtual machine when I use FlyCapture.

I built this code and followed this rebuilding of the library, but the library can't find my Flea3 camera. Do you have any ideas about this?

What camera you have and what system you are on? What is your cameras vendor and product numbers?

Artem gravatar image Artem  ( 2013-10-30 05:53:54 -0500 )edit

Ubuntu 12.04 Flea3 Color. Flycap can recognize the camera, but this script cannot. I'll get the vendor/product numbers in a sec

If your vendor number and product number is not listed in the structure in libdc1394-2.2/dc1394/usb/control.c you have to add it. Then you can also try to install coriander (sudo apt-get install coriander) and see if you can get access to the camera through it.

You may check XIMEA cameras which explicitly supports OSX and Linu

I've checked your link. The cameras look good, unfortunately we've had point grey cameras for about 2 years.

I also followed the instructions but neither my own code nor the small program provided to display the GUID worked. Then I added 5 additional lines to control.c, providing entries for device id numbers 0x3001 - 0x3005. After recompiling everything, the test program now reports GUID b09d0100ace819 and my own program reports "Flea3 FL3-U3-32S2M". I haven't done the testing to determine which of the 5 lines I added was the one I needed; they probably all correspond to a slightly different flavor of the camera.
