谷歌云愿景与谷歌存储

Question

I am making a text detection application, using google vision api.

I want to figure out the way for a OCR detection function be able to load the jpg file.

This is a code referance I get from google codelab , but when try to open the url= gs:// like the diagram demonstartes, the error message saying invalid arguments . I wonder if I have missed anything??

Then, i found out that, when it is deployed on cloud functions, google vision will load image from storage . but HOW? I can not find any relenvant documents giving a detailed process about this. I am new to the code and bad at finding these instructions. Does anyone knows how can I successfuly reads/connect to the jpg file? or maybe provide a reference link regarding this? Thank you!

Answer 1

The code on my end is running fine and appears to be correct, I just copied the code and run it through Google Cloud Shell, Be sure to install the Vision API python client library in your cloud shell: pip install --upgrade google-cloud-vision If your intention is to open the the image you can access the image sample provided in the reference you mentioned here: https://storage.cloud.google.com/cloud-samples-data/vision/text/screen.jpg the uri provided in the code is the resource location of the image that is stored in Google Cloud Storage, the link above is the url equivalent of it.

Output:

I would suggest reading through official documents for more information about the API using client libraries here and although different implementation you can view this OCR usage here .
