zorg-network-camera 0.0.2

Python framework for robotics and physical computing.

This module contains device adaptors and drivers that make it possible to connect network cameras to your robot.

Installation

pip install zorg-network-camera

Network Camera Adaptor

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.

Camera Feed Driver

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.

Light Sensor Driver

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.

OCR Driver

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.
