remote openCV with raspberry pi

this is an example about how to use remote object detection based on openCV and zeromq framework.

requirements

• opencv(python) as cv(opencv) and cv2(numpy)
• zeromq(python)
• gevent(light weight switch)
• knowledge about img process
• profile, logging each stage mem and cpu time

method

• Server
  • capture img
  • send img to clinet
  • wait for next command from client
  • update status by new command
• Client
  • receive img
  • run all detection
  • build up a new command based on detection results

detections

• face detect
• circle detect
• line detect
• find attribute obj

how to run it?

• python poll_camera.py (using cv to capture/show img via remote protocol)
• python poll_camera2.py (using cv2 to capture/show img ...)
• python poll_thread_run2.py (using cv2 to run all thread detection based on CPU num)
• python poll_series_run2.py (using cv2 to run all series detection ...)
