yin-yang-ranch: Software & Raspberry Pis that Manage a Farm

Introduction

yin-yang-ranch is a collection of Python programs and Rasperry Pi hardware to help manage a small urban permaculture farm. The 2 acre farm is an ongoing science project to build living soil, capture rain in barrels, and grow a

API and Usage Examples

The API for imagezmq consists of 2 classes with 2 methods each. The ImageSender class has 2 methods: one for sending an OpenCV image and one for sending a jpg compressed OpenCV image. The ImageHub class has 2 methods: one for receiving an OpenCV image and one for receiving a jpg compressed OpenCV image.

Using imagezmq in Distributed Computer Vision Projects


The test programs show how imagezmq can be used to capture images on Raspberry Pi computers, send them to a Mac via imagezmq and then display them on the Mac. The ability for one hub to gather and process images from multiple sources allows computer vision pipelines to distribute vision processing across multiple computers.

imagezmq: Transporting OpenCV images


Introduction


imagezmq is a set of Python classes that transport OpenCV images from one computer to another using PyZMQ messaging. For example, here is a screen on a Mac computer showing simultaneous video streams from 8 Raspberry Pi cameras:

          PURPOSE:
        

        

          
              These classes allow a headless (no display) computer running OpenCV code
        

        

          
              to display OpenCV images on another computer with a display.
        

        

          
              For example, a headless Raspberry Pi with no display can run OpenCV code
        

        

          
              and can display OpenCV images on a Mac with a display.
