[HOW-TO] Capture continuous images from a stream #370

Closed h-robotics closed 2 years ago

h-robotics commented 2 years ago

Hello, I'm a beginner and I'm working on adding a text recognition feature for a robot I'm building using opencv and pytesseract. The tutorials I've found use the older picamera library and I've been looking for an alternative to the command picamera.capture_continuous and have not found it. Any ideas how to do this?

I don't think there's an API that is exactly the same, you would just put a capture_array or capture_file inside a loop. Here's one of our standard examples, showing one way to implement a continuous preview with text recognition: https://github.com/raspberrypi/picamera2/blob/main/examples/ocr.py
