Using Python 3 + Google Cloud Vision API's OCR to extract text from photos and scanned documents

Just a quickie test in Python 3 (using Requests) to see if Google Cloud Vision can be used to effectively OCR a scanned data table and preserve its structure, in the way that products such as ABBYY FineReader can OCR an image and provide Excel-ready output.

The short answer: No. While Cloud Vision provides bounding polygon coordinates in its output, it doesn't provide it at the word or region level, which would be needed to then calculate the data delimiters.

On the other hand, the OCR quality is pretty good, if you just need to identify text anywhere in an image, without regards to its physical coordinates. I've included two examples:

####### 1. A low-resolution photo of road signs

A ideia é ter um Linux virtualizado no windows, que dê para rodar o docker e usar o vagrant como um sistema sobre o Windows. Para não precisar de fazer dual boot, já que tudo o que eu preciso é um terminal Linux que eu posso instalar qualquer coisa com apt-get :)

Instalar no windos o cmder, um emulador de console http://cmder.net/
Instalar virtual box https://www.virtualbox.org/wiki/Downloads
Instalar o vagrant
