I am exploring features of Cloud Vision API and I was wondering if there is any way to detect dimensions of an object under label detection. For example, if you take a picture of a car on street, then Cloud Vision API would return dimensions of the car (length, height or width)
LABEL_DETECTION will return an EntityAnnotation. For the field boundingPoly the documentation states: "Image region to which this entity belongs. Not filled currently for LABEL_DETECTION features."
So no, no at the moment it does not return dimensions. This is the related question.
Just to be clear it would always return dimensions in image space i.e. pixel coordinates, never in object space, i.e. physical dimensions of the object.
