Wireless camera system for OpenCV (mounted on quad)

Posted by Jesse Adler on July 12, 2014 at 9:04pm

Dear lovely people,

I am wanting to find a camera and wireless transmission system that I can use to track moving objects on the ground from a quadcopter. The image data will be analysed on a computer in OpenCV.

Like this: https://www.youtube.com/watch?v=v9KjAdvPF0o

Signal latency must be kept to a bare minimum and a frame rate of at least 30FPS is also needed. Also the higher the image resolution the better. I am debating between digital vs analog transmission.

Anyone done anything like this before? Or can recommend suitable cameras and wireless transmission technology that can interface with a computer?

Many thanks!

    Yes, we already support wireless camera and OpenCV, running either onboard on an Odroid board or on the ground. See this post for more.

      Thanks for the reply Chris! 

      I read that post, but I still have questions about the best way to get data quickly to a computer on the ground. I want to do it digitally if possible but I think high latency is going to get in the way. Still searching for a camera and transmission system that will work. Once the images arrives at the computer I have no worries manipulating the data.

        Hi Jesse,

        Just wondering. Have you figured out based on your experience of any reliable wireless video transmission with reasonable cost which can be used for processing (e.g. opencv) later? I find normal ip camera quite laggy due to its latency.
