I am working on image processing project where working on frames taken by camera using raspberry pi. So i want to know which is better ? to use pi camera or usb cam , Hint : required good camera as the mouse is moving corresponding to object detected by camera.
Most obvious difference is , you can have USB cameras based on pixel quality and zooming and resolution; whereas Pi cam is limited:)
For image processing preferably using opencv ; you need to think on frmes per second , and do little research on SD Card speed as well ,because slower SD card will slow performance as well
