MATLAB: Calculating volume from a photo

Image Processing Toolboxvolume

Hi! I want to ask is there a way to calculate the volume of wine inside the wine glass like in this photo? Or do I need more photos of this wine glass from different perspectives?

Best Answer

We can't see your photo. But if you assume the glass is round, and if you've calibrated spatially, then you should be able to calculate approximate volume. You may need to throw in a small fudge factor to account for the refraction near the edges. To do that you could fill the glass with known volumes, then measure the area in pixels and calculate the volume. Prepare a function to transform the pixel volume into an actual volume in milliliters.

MATLAB: Function estimateWorldCameraPose() or extrinsics() for fisheyeParameters is missing. Is it possible to change these functions for fisheye

fisheyeIntrinsics can't be used directly. Instead, you can use undistortFisheyeImage function to produce both undistorted image for further processing and a "virtual perspective" camera intrinsics. See syntax which returns "camIntrinsics"

The new camIntrinsics can then be used in workflows involving a pinhole camera. It is a virtual pinhole camera created from the original fisheye camera. This new intrinsics object (non-fisheye) can then be fed into estimateWorldCameraPose.
