This module contains device adaptors and drivers that make it possible to connect network cameras to your robot.
pip install zorg-network-camera
This module's network camera adaptor handles the basic functions of retrieving images from the remote camera when necessary. Because this module is intended to run on devices such as the Intel Edison or the Raspberry Pi, the adaptor has been designed with additional features for efficiency. Mainly, if an images are cached until the image from the remote camera has been updated. This ensures that an image will not be unnecessarily downloaded onto the device.
The Feed module provides a driver for accessing the url to of the
remote camera's image. This is a convenience method intended to be used
to load the image into your application.
The LightSensor module allows you to use the camera as a light
sensor. This driver provides the ability to get the average lighting
level from the camera.
Optical character recognition (OCR) is the process of programmatically
converting images of typed, handwritten or printed text into
machine-encoded text. The OCR driver module provided in this package
provides a utility that makes it possible for your robot to process
written text that it sees.
The OCR driver achieves the process of extracting text from an image through the use of the open source Tesseract OCR module. Tesseract is an optical character recognition engine origionally developed by Hewlett-Packard. Development of Tesseract has been sponsored by Google since 2006.
