ganbat6093@, could you provide more info as to how to repro? A codepen/jsfiddle
would be great, together with the versions of Chrome and Win used.

Both RawValue and BoundingBox have been supported on Android Platform that can detect Latin language [1].

Text Detection on Mac with CIDetectorTypeText[2] API only finds areas that are likely to contain upright text, but does not perform optical character recognition, so the rawValue is "".

Maybe the BoundingBox on Windows is a bug that need to be fixed with OcrWord.BoundingRect[3] Property.

The demo provided by you in the codepen is not working. I tested the Windows 10, Chrome Version 67.0.3396.99 (Official Build) (64-bit). I attached the output screenshot.
Text detection work find but Bounding box values are all 0.
The code link is https://codepen.io/miguelao/pen/ygxVqg 

Then I tested it on Mac, Chrome Latest build too. In the MacOS, Bouding box values are all fine, But texts[i].rawValue is empty.

ganbat6093@, thanks for the info, could you please try with Chrome Canary
as well?

Tried testing the issue on Win-10 using chrome latest stable #67.0.3396.99 and latest canary #70.0.3507.0 as per comment #4.
Observed that after navigating to https://codepen.io/miguelao/pen/ygxVqg and clicking on the "Detect the text" button, an error appeared as text detection not supported.

mcasas@ - Could you please provide any other sample file /url to test the issue from TE-end.

Thanks...!!

#6: you probably need 
  chrome://flags/#enable-experimental-web-platform-features
enabled

Thank you for providing more feedback. Adding the requester to the cc list.

mcasas@chromium.org I tried with Chrome Canary too, Windows 10. BoundingBox values are  0 as well. 

On my android phone Text detection API works fine with Android Chrome.

ShapeDetection: Get bounding box in the line of Text on Windows 10

The OcrLine[1] has no BoundingRect properties, so the result of bounding box
need to be calculated by the words in the current line of text.
