3.3.37. Google Cloud Integration. (Google Vision OCR and Google Geolocation API)

Since version 1.0.2.73 Some Google Cloud services can be integrated into ChronoScan Capture:

There are two ways of using the Google Cloud Services with ChronoScan Capture.

Using the ChronoScan Service account
Using an external Google Vision Cloud application own and managed by third parties

1. Using the ChronoScan Service account

When using the ChronoScan Service account credits are required and must be bought as a plug-in package.
The ChronoScan service account is already configured to use both Google Vision OCR and Google Geolocation API and it provides user customization within ChronoScan Desktop.

1.1 Activation

Buy Google Vision credits
Open ChronoScan Desktop > 'Scan/Input' tab > 'OCR Read' menu > 'Active OCR engine' submenu > Select 'Google Vision OCR'

Now our active OCR is the Google Vision OCR, and we can configure it and make sure the endpoint server is working properly

3.1. In 'Scan/Input' tab > 'OCR Read' menu > Select the 'Active OCR Settings' option and the configuration window opens

3.2. These are the configuration options for the ChronoScan Service account:

Property	Value	Description
Service account configuration / Service account	Type: String Default: ChronoScan integrated service (Requires credits)	Here is where we choose the type of integration with Google Vision. Since we are configuring the ChronoScan Service account, make sure the selected option is: ChronoScan integrated service (Requires credits)
OCR settings / Endpoint	Type: String Default: EU	Enpoint server location for Google server to execute. EU / Europe US / United States of America
OCR settings / Compression level	Type: String Default: Auto	Compression level for processed files for Google Vision OCR Auto / Prioritizes performance over speed Low / Prioritizes speed over performance * Google Vision API has a file size limit. Documentation about it here.

4. The endpoint connection can be checked by clicking on the 'Test server button'. If the status code is 200, Google Vision OCR can be used in ChronoScan as any other OCR engine.

2. Using an external Google Vision Cloud application own and managed by third parties

*Since version 1.0.2.92

Requires an advanced or enterprise license

An external Google Cloud application can be used in ChronoScan through and API_KEY
When using a Google Cloud external application, creating, configuring, managing and billing for the Google Cloud application are completely a responsability of the owner of that external application

2.1 Activation

Important: To be able to use Google vision OCR and Google Geolocation API, both APIS must be enabled on your Google Cloud app.

Create/ have a Google Cloud application.

2. Generate a valid API_KEY external application console and provide it to ChronoScan in the configuration window
