"Nice project! You write you support HDMI input camer. How do you connect the camera to the board?"

"Hey @OlliW, we have a code that will work on most of the companion computers like RPi, Odroid, Orange Pi, BananaPi, Nvidia TX2 with ubuntu, python, and OpenCV for python installed. As long as they have at least one USB 3.0 port.  As for the…"

"Hello Greg, Has you tested OpenCV on any embedded system? Do you think Jetson TX2 could do stabilization, tracking and h264 encoding at time? "

OlliW commented on Greg Dronsky's blog post First DIY Zoom Gimbal
"Hey Greg many thx for the explanations I'm a bit confused now as regards to what is what, too many key words (2 axis, Sightline, Snapdragon, ...) from which I can't piece together what you are doing (as opposed to what else options are…"

"Hi OlliW, we are using opencv to capture good features to track in the feed and then move the video matrix so that the picture is cleaned from rapid shakes visible in full zoom. This takes some computing power to achieve but is effective. Some video…"

"I am not Greg! Yes, we talk about the same, stabilize the image by software. I mean when you have all zoom in you could need than stabilization algorithm could control gimbal, but it the same algorithm, yes, to compensate yaw…"

OlliW commented on Greg Dronsky's blog post First DIY Zoom Gimbal
"Hey Greg thx for the quick response I'm not sure I understand what you're saying though, maybe because we mean different things by "stabilization". I was thinking terms of video stabilization, i.e., there e.g. vibrations, jello…"

jlcortex commented on Greg Dronsky's blog post First DIY Zoom Gimbal
"OlliW, Maybe even in the opposite direction, that the stabilizer acts on the gimbal to maintain a frame and compensate the drift of the sensors.  You are doing a great job with the STorM32, I would like to face the development of a camera for…"

OlliW commented on Greg Dronsky's blog post First DIY Zoom Gimbal
"hey Greg > We have a digital stabilisation code that works, now this is interesting. Maybe I can ask: Does your stabilization works only on the video feed, or does it also in addition use data of some sensors (gyro e.g.)? cheers, Olli"

"Hi Jose, we provide a USB 3.0 variant of the 30XHD V3 gimbal. It allows a very straight forward connection to a Rpi, Odroid or Tx2. We have a digital stabilisation code that works, but it is not yet implemented in the gimbals."

"Greg, Do you slow movements when zoom in? I see you have another cameras with digital output, Has you researched about tracking and digital stabilization for this sensors?"

"Damian, it is a surveillance camera, it is PAL, same format you can transmit with any analog video TX. It is not a to make nice youtube videos. it has not bad look: https://www.youtube.com/watch?v=GT2LSM2xZFc"

How a Tribe is Battling Loggers With a Drone They Built Watching YouTube

In Guyana, where forests cover over 80 percent of the country, the threat of illegal logging is ever present. A lot of the time, it’s hard to even know if it’s happening. That’s in part because the country’s population is so small, just 735,000 people to keep watch on 83,000…
