Yes I think processing video through arduino is not an option.
Arduino camera with osd Pc#
Removing the housing and connectors should reduce the size and weight.Īnother possibility may be to use a keychain camera to record video and a GPS logger then combine them using a PC to combine the data. It should be possible to find a small DVR and strip the circuit board out of it. But then you could not add the OSD and it would still be too much for Arduino. It may be possible to get the video data from there to reduce the processing. I dont plan to do FPV right now, I just want to hook up the cam and have onboard recording which I can view after the flight. Some board cameras have extra connectors which include a digital interface. 2 megapixels image sensor OV2640, build-in 650nm IR block filter, visible light only. Features : Compatible with Arduino, Raspberry Pi Pico, MCU, Raspberry Pi, ARM, DSP, FPGA platforms. You wouuld need a video speed ADC and then processing power to handle many mega-samples per second to create a format to store on the card. Arducam Mini Module Camera Shield with OV2640 2 Megapixels Lens Compatible with Arduino UNO Mega2560 Board and Raspberry Pi Pico.
The Ardino won't be up to processing video not fast enough. That way, once on the ground, you can record the signal on your pc or television or whatever hardware you might have availble and isn't portable. Then add an option to the arduino to perform a playback. Not sure if it's possible but if you can modify the signal with arduino, then maybe you can also record that same signal in a very raw unreadable format to some sdcard or other storage. matches the clock-speed anyway, so it doesn't really matter as they will get "scaled" as well. The pixels will be a bit shorter but that's the only difference you will notice. You have to change the serial-settings, but except for that everything should work. It would be interesting to do the same sort of project in ARM7 but I don't have that much spare time.Ĭhanging the clock-speed/crystal to 20 mhz shouldn't be any problem. The effort needed improve Arduino is probably worth it. Service would have to be kept short and allowed only when there was enough time, probably with the bulk of the service being delayed and then not allowed to run over.ĭennis has done a great job with this project, it works very well and experimenting with it is a good way to learn about Arduino. Timing is critical when outputting pixels, so interrupt service would be a problem then. The user can view the neck protection No interrupt and overlay text and/or graphics onto a video. I think a lot of the hardcoded delays are very short and precise, so there wouldn't be much or anything to gain. This is a MAX7456 OSD (on screen display) For Arduino.
