Download

The GUI for recording is installed on the Eyesisbox PC by default.

There are several ways to install a newer version:

Terminal: 

cd <any-path>
git clone git://elphel.git.sourceforge.net/gitroot/elphel/eyesis4pi_gui (initial checkout)
git pull (update)

SF.net: 

http://elphel.git.sourceforge.net/git/gitweb.cgi?p=elphel/eyesis4pi_gui;a=tree

Follow the instructions in INSTALL.txt: 

1. Install the following packages, terminal:
 sudo apt-get install php5 apache2

2. Make the src folder visible to the web server:
2a. Create a link, terminal: "sudo ln -sf <path-to-eyesis4pi_gui-folder> /var/www/eysisgui"
2b. Or copy all the files to /var/www/eyesisgui.
Note: "/var/www" is the (apache2) web server's document root folder.

3. Make the footage root folder "/data/footage" writable for everyone.


Equipment/Package

  • Eyesis4Pi
  • Switch
  • PC / Laptop



Power On

  • Turn the switch on.
  • Connect the camera's ethernet cables to the power enabled ports. The camera boot takes about 1 min.

Important Notice: Use a fan to cool the camera's pole when shooting indoors.



Network Set Up

IP address: 192.168.0.68 (example)
Mask:       255.255.255.0

Note: Eyesis4Pi's default IP addresses: 192.168.0.221-229

System Tests

  • Open the GUI page (the address is bookmarked in the Firefox and in the Chrome). The GUI address is:

http://127.0.0.1/eyesisgui/index.html

  • Go to the "Settings" -> "Test"-tab:
  • Follow the Open the test page-link, the tests are:

1. All the modules are online.
2. GPS locked
3. IMU detected
4. Internal CF cards are present



Setting recording parameters: storage paths

  • Check paths at the Settings -> Recording-tab

Absolute footage path - the path to the folder where all the footage series are stored. Must be writable to everyone.
Series subfolder - created automatically
Files limit in a subfodler - number of files stored in a subfolder inside Series subfolder

CF card device name - GPS/IMU log is saved to the internal CF cards. On the master camera they are /dev/hda1 & /dev/hdb1
GPS/IMU log file name - absolute path (in the master camera)+ log base name
Starting index - logs are named as follows - [base_name]-[index]
Records per file - number of records per log file. New file: an incremented index is added to the base name.



Setting recording parameters: camera settings

  • Check camera settings at the Settings -> Camera-tab

Trigger period,ms  - 1/FPS.
Skip frames mask - hex 0x1ff - bit[8]=enable, bits[7:0] - 1 - record frame, 0 - skip frame - in an 8-frame sequence.
HDRVexpos - in the HDR mode - the darker frame multiplication coefficient to get exposure for the lighter frame.
AutoExp max, ms - the autoexposure value limit.
AutoExp level - value of a pixel at which the autoexposure works.
AutoExp fracpix - number of pixels below the Autoexp level.
AutoExp frame ahead - number of previous frames used for calculatin the current frame exposure.
Compression quality - JP4/JPEG compression quality.

HDR mode - at the fps rate the dark and the bright images alternate.

Skip Frames Mask: 
  0x1ff - frames are not skipped, camera is triggered at Trigger period.
  0x155 - the camera is triggered at Trigger period/2 but only every other frame is recorded. It makes autoexposure adapt quicker and in the HDR mode records only normally exposed images skipping the underexposed ones.

Recommended values for 1 fps:
Trigger period = 1000 (ms)
Skip Frames Mask = 0x155
HDR mode = On



Recording

  • Record-button to start recording



Stopping

  • Stop-button for stop.



Downloading IMU/GPS Log

  • After stopping - go to the Settings -> Recording-tab to download the IMU/GPS log.



Checking the Recorded Footage

  • Check the footage at the Absolute footage path - each panorama set should consist of 9 images named with a timestamp of when it was taken plus the index of the camera (seconds_microseconds_index.jp4):

Note: Missing files most likely means that the FPS is too high.
