Enter the catkin work space
cd YOUR_ROS_WORKSPACE/src
git clone https://github.com/gaowenliang/ptgrey_reader.git
cd YOUR_ROS_WORKSPACE/src/ptgrey_reader/install/usb/
tar jxvf libusb-1.0.21.tar.bz2
cd libusb-1.0.21/
Follow the INSTALL file to make and install the libusb library:
./configure
make
sudo make install
The driver supports the computer with Intel CPUs and NVIDIA TX2.
- For computer with Intel CPU:
cd YOUR_ROS_WORKSPACE/src/ptgrey_reader/install/amd64/
tar zxvf flycapture2-2.11.3.121-amd64-pkg.tgz
cd flycapture2-2.11.3.121-amd64/
- For TX2:
cd YOUR_ROS_WORKSPACE/src/ptgrey_reader/install/arm64/
tar zxvf flycapture.2.11.3.121_arm64.tar.gz
cd flycapture.2.11.3.121_arm64/
Follow the README file. Install requirements:
sudo apt-get install libraw1394-11 libgtkmm-2.4-dev libglademm-2.4-dev libgtkglextmm-x11-1.2-dev libusb-1.0-0 -y
Install Flycapture2 driver library:
sudo sh install_flycapture.sh
Build the package:
cd YOUR_ROS_WORKSPACE/
catkin_make
Before using that you may need to give them enough authority
sudo gedit cd /etc/udev/rules.d/40-flir.rules
Change all the 0613 or 0664 to 777 in the "40-flir.rules" and save. Then restart the system.
Use rosrun the camera_list to see your camera ID number.
roscore
rosrun ptgrey_reader camera_list
The camera infomation will be shown in screen, such as:
FlyCapture2 library version: 2.11.3.425

========== CAMERA INFORMATION ============
Serial number | 17221110
Camera model | Chameleon3 CM3-U3-13Y3M
Camera vendor | Point Grey Research
Sensor | OnSemi PYTHON1300 (1/2" Mono CMOS)
Resolution | 1280x1024
Firmware version | 1.13.3.0
Firmware build time | Tue Nov 15 18:35:47 2016
Done! Press Enter to exit...
Copy the Serial number to launch file as device, and launch.
roslaunch ptgrey_reader single.launch
After launch the camera, there will be a ROS topic named /pg_YOU_SERIAL_NUM/image_raw, such as /pg_17221069/image_raw. The type is sensor_msgs/Image.

If is_grey is true, there will be a extra ROS tpoic named /pg_YOU_SERIAL_NUM/image_grey.
If is_roi is true, there will be a extra ROS tpoic named /pg_YOU_SERIAL_NUM/image.
The ROI and down sample with such two step rule:
- step1: crop ROI image
- step2: down sample, with
down_sample_scale<= 1.0
The Hardware trigger is to capture an image while the camera received a trigger signal. An extra trigger cable is required.
Buy the elements of the trigger cable in JST NSHR-09V-S and JST ASSHLSSHL28W51.
Set is_sync as true in the launch file. And make sure the rate is larger than the trigger signal frequency.
If progrem cannot run successfully, especially for muti-camera system and high FPS system, change the USB buffer before roslaunch the progrem:
sudo -S sh -c 'echo 2048 > /sys/module/usbcore/parameters/usbfs_memory_mb'
Ps: 2048Mb is not required. Any buffer size is OK.
