[Elphel-support] Collecting Visual Inertial Data with NC353L-369-IMU-GPS

[Oleg]

Hi,

The camera's network is 100Mb.

a.
Individual images can be downloaded from: http://192.168.0.9:8081/bimg (use
"wget")
There is a way to trigger image acquisition from http requiest:

b. as for IMU data
I haven't tried this - you can try to create an nfs partition on you PC and
mount it on the camera - then try to store the log. Not sure if this is
fast enough.
or
IMU is 2.5kHz - the network is slower but I could think of a way to send a
buffered log or something like this...

2. I tried to record the Image in the disk. However, when it gets to 19.63
> MB the program just stopped immediately. Could you please let me know if

It's most likely the CF card is not mounted.
Could you send me the output of the following commands:
a. dmesg
b. mount

3. In the first email I exchanged with you, I asked if there was a ROS

Never tried it.
Basically it is a standalone ip camera and doesn't need a pc driver. The
images are updated at:

> http://192.168.0.9:8081/bimg


If ROS tools support multipart jpeg then:

> http://192.168.0.9:8081/mimg


What's your pc os, btw?
