using tcp/ip

1. run script

   git clone https://github.com/ivalab/aruco_tag_saver.git
   cd aruco_tag_saver
   python camera_demo_arucoTag_5X5_250.py.py

2. default port is 2328

using Kinect

1. install libfreenect for kinect (warning: never do upgrade)
2. calibrate kinect
3. run script

   git clone https://github.com/ivalab/aruco_tag_saver.git
   cd aruco_tag_saver
   python camera_demo_arucoTag_kinect.py

4. press s to save rgb/depth/rawDepth images
5. press t or g to tilt up or down kinect
6. change the parameters:
   ```

   CHANGE-ABLE PARAMETERS

   OBJECT_TYPE = “scoop”
   CAM_POSE = 0
   OBJ_POSE = 0
   START_COUNT = 0

tmpPathGT_pose = ‘./data/graspPositions.txt’
tmpPathGT_ar = ‘./data/arucoPositions.txt’
tmpPathGT = ‘./data/graspPoseLabels.txt’

### change tilt range for kinect
1. `tilt.c`:

define MAX_TILT_ANGLE 91

define MIN_TILT_ANGLE (-91)

2. `glview.c` (optional, only if you want to use this example):

if (key == 'w') {
    freenect_angle++;
    if (freenect_angle > 30) {
        freenect_angle = 30;
    }
    tilt_changed++;
}

…
if (key == ‘x’) {
freenect_angle—;
if (freenect_angle < -30) {
freenect_angle = -30;
}
tilt_changed++;
}
```

1. remove libfreenect.so and libfreenect_sync.so under /usr/lib/x86_64-linux-gnu/
2. make and make install libfreenect.so and libfreenect_sync.so and load libraries
3. run Cython setup.py to generate module and link to new .so
