Hello, I want to make a robot that controls the motors and sensors with an arduino mega 2560, and uses an openMV camera to detect a blue box while line following at a relatively fast speed. It also needs to be able to detect balls, decide their colour and segregate them. Which camera is best for such an application, openMV h7 plus or openMV R2. the camera should be able to communicate with the arduino. The ball and box detection and classificcation part should be handled by the cam.
Since:
- you want to be fast
- the project isn’t so resolution demanding
I prefer the h7 r2 instead of the plus one.
will there be a considerable drop in the res
Yes, resolution hurts image processing speed though in general. The H7 R2 is faster than the plus for smaller resolutions because it doesn’t do anything using SDRAM.
is it possible to see a picture of the openMV H7 R2 camera feed so i can check if the resolution is good enough for my applications
dear friend if you try to find balls in an image resolution isn’t must.
The most you have to worry is the lighting conditions .
Resolution 640 x 480 is the camera. Maybe you will have to reduce it even more though to go faster depending on your needs.
Generally don’t bother about the resolution for this project.
