To be able to efficiently send the image data over a wireless datalink, one option is to compress the video data using h264/h265 encoders. Those two are often implemented in a hardware-accelerated way on the onboard computers like RPI and Jetson Nano. We can use these encoders to compress the video data to about 1000kBit/s and keep some kind of acceptable quality in the images to be processed by the image analysis algorithms ( to be tested! ) on a basestation computer. | To be able to efficiently send the image data over a wireless datalink, one option is to compress the video data using h264/h265 encoders.

+ | These kind of compression is also used in existing solutions mentioned in https://www.hs-augsburg.de/homes/beckmanf/dokuwiki/doku.php?id=searchwing-wifibroadcast. | ||
