Freeture ported to ARM64 #35

Open gmke opened 7 years ago

gmke commented 7 years ago

I have ported Freeture to the ARM64 architecture and used Aravis 0.6, boost 1.65 and OpenCV3.3. It runs stable on an Odroid-C2. We will use this setup for the Fripon-Cam at the Kepler observatory in Weil der Stadt, Germany. If somebody can find some time, adding a native camera support module for Basler cameras using Pylon5 (now available for ARM64) would be good. Although Aravis is a good idea, it lacks a lot of camera setup possibilities and has some performance limitations.

first test night completed, no failures, no buffer underruns

our system now completed the first month of regular operation without any problems. We run with 20fps to have a bit longer exposures and avoid missing packets. The system can cope with up to 24fps. The full 30fps would need a working jumbo packet feature. Unfortunately this is broken in the current version of Ubuntu 16.04 for the Odroid C2. Average load is 2.3 with 4 cores, plenty of cpu time reserve for the generation of the pictures and movies and running the webserver. My version of freeture is available on https://github.com/gmke/freeture/

I have used the custom size option in freeture to reduce the image size by 30%. With this payload reduction, its now possible to get the full 30fps with MONO16 and no packet errors. Unfortunately, there is no way to set the offset of this ROI. I directly changed the source code. It should become a parameter in the configuration.

I have created a group to discuss Fripon and Freeture. Please join at https://fripon.groups.io/g/main.

Long ago I have taken this into discussion. You can check details here https://github.com/fripon/freeture/issues/17

it is easy to implement, they actually already use the arv_camera_set_region () function in the Aravis camera module CameraGigeAravis.cpp. arv_camera_set_region (ArvCamera *camera, gint x, gint y, gint width, gint height); in the code, but with x and y set to zero. I changed it to my needs.
