Reality Capture API get JSON parse error after authorize!

Anonymous — Wed, 13 Dec 2017 04:53:57 GMT

I've trying to use the Reality Caputre API to convert 2d photo to 3d model with example on:

https://github.com/Autodesk-Forge/photo-to-3d-sample

But when after I finish authorize, the browser cannot load the explore.ejs engine with error at the console:

SyntaxError: Unexpected token o in JSON at position 1

200 - [object Object]

Please help me, I really need this api to use for my project.

Hi,

Sorry for the inconvenience! Some recent "Content-Type" header updates on our service broke our sample.

I've posted the fixes on my GitHub fork https://github.com/eugene-chua/photo-to-3D-sample

HTH,

-Eugene

Hi @eugene.chua

Thanks a lot for your support. The project is now working but I don't understand after following the instruction until I press the "get result" button, It's return a message include an error code:

Error":{"code":"22","msg":"Data is not ready"}

I don't know this thing is problem or an api is working? And the result of this project is return the 3d model object or only the JSON data? Please help.

Thank you.

That's good news!

You scene is currently processing. If you click on the "Get Results" button after a few minutes, you should get a valid download link in the response.

Great! The problem was solved! Thank you very much @eugene.chua. Can you explain me how can I get the photo from my local computer, not from aws link in phototo3d.js? I've tried to override these link but it's cannot convert. Please help.

For direct file uploads, you can refer to the “Step 3 - Uploading Files Directly” section of the tutorial https://developer.autodesk.com/en/docs/reality-capture/v1/tutorials/create-3d-mesh-from-photos/

If you are familiar with cURL, you would need to make a call similar to ...

curl -v 'https://developer.api.autodesk.com/photo-to-3d/v1/file' \
-X 'POST' \
-H 'Authorization: Bearer eyjhbGCIOIjIuzI1NiISimtpZCI6...' \
-F "photosceneid=hcYJcrnHUsNSPII9glhVe8lRF6lFXs4NHzGqJ3zdWMU" \
-F "type=image" \
-F "file[0]=@c:/sample_data/_MG_9026.jpg" \
-F "file[1]=@c:/sample_data/_MG_9027.jpg"

To prevent timeouts, I would recommend uploading only one file at a time (instead of multiple files in a single call)

If you are modifying the node.js sample code, you will have to use the Uploading Files feature of the unirest library (http://unirest.io/nodejs.html), for example ...

	unirest.post(endpoint)
	.header('Accept', 'application/json')
	.header('Content-Type', 'multipart/form-data')
	.header('Authorization', 'Bearer ' + access_token)
	.field('type', 'image')
	.field('photosceneid', sceneId)
	.attach('file[0]', urlArray[0])
	.attach('file[1]', urlArray[1])

You should also remove the '@' prefix from your file paths.
