> TEST CAM! GET RUNNING PICTURES!
1. setup virtual machine to test
> 8 cores, 16GB RAM, 2 TB for 1cam
> 48 cores, 128GB RAM, 6 TB for 6cam
2. use laptopt to test
3. (opt/later) setup tower1 (defunct again!) as cheap testing machine!
> get NIC working
> give name connect inet
--> as terminal to connect to server
--> later: use for DMX lighting
4. (alternatively) Raspberry Pi
Q: is option fast enough for processing of 1/3/6 streams simultaneously?
> test bottleneck (CPU,HDD,ethernet,)
> is video compression on? how demanding!
> storage: 1 minute hochrechnen. mit 24/17/12 FPS.
Q: how should workflow look?
> Option A
1. record and store (where)
2. process (where?)
> Option B
1. record, process (cut ROI to reduce size), store
2. more processing (R..)
--> what processing.
--> draw picture as doc of workflow

* setup 1 fridge

> get video in VV > get video in SW-A via SDK
> cam calibration (Use Viewer? Or own SW?)
> configure cam settings
* get video for 3 cams in one workstation
> what SW?
> calculate supported framerate+resolution+codec for hardware (CPU,RAM,HDD...)
> or do tests and see if frames are dropped
DONT do a diskbench to get writing speed (calculate needed speed with 3 cameras) to see if frames will be dropped or not...
writing speed of one of the workstations is 150MB/sec
prosilica gtx1920 needs 3x 107.53 MB/sec for BGR. 1x for MONO
avi uncompressed
1280x1280 @ 40 fps is limit for your CPU oO
CPU can compress 47mio pix/second
17x1936x1456=47mio -> 17fps @ full res
suggested CPU i7 3840
reduce ROI

B) recorder - camera produces frames and timestamps

All APIs cover the following functions:
Listing currently connected cameras
Controlling camera features
Receiving images from the camera
Notifications about camera connections or disconnections
> browse other examples a bit:
list cams / features / actioncommands

From Thomas:
* recording single frames in data structure
* used Vimba.2.1 (1.6 more likely) * compress each frame with loosely jpg compression
(used framework opencv version 3.2. imwrite function with parameter: IMWRITE_JPEG_QUALITY 100 ; IMWRITE_JPEG_OPTIMIZE 1; IMWRITE_JPEG_RST_INTERVAL 4;)
* stores timestamps for each frame in milliseconds
SW viewer [optional]
###############################
how?
Wie ruft man die index.html auf der VM auf?
Wie kommunizieren SW REC und Viewer?
eg. OnStopButtonClicked( cmd( ../camTrack3000 --stop ) ) ??
REST-Server/ HTTP-Json / ..
C) background subtraction
###########################
ctb - calculates centroid points of all frames in a record

> update bgs alg. opencv4 has its own bgs?
D) process scripts
###########################
ctd - calculated the mean speed in pixel / millisecond
* can i reduce size of data (reduce length|fps|res)
>> calc D) for test data set (get data from joerdis?)
-> with all frames
-> undersample, shorter length
-> compare results. same?
