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

; 当要打开一个symbolink的时候，如果symbollink到一个被git（或者其他vc）管理的文件时，emacs老问
; Symbolic link to Git-controlled source file; follow link? (y or n)
; 配置下这个变量就好了

(setq vc-follow-symlinks nil)

; nil 表示 不要问，no
; ask 表示每次都问
; t  表示follow
