Stockpile Measurement Project

I am requesting tips/recommendations for spec’ing out a camera/gimbal for volumetric measurement of a stockpile (wood chips/wood shavings). I’ve researched enough to see I should probably avoid any wide-angle style lens like that of a GoPro or similar action camera. But, would like to find a cost effective solution without purchasing a high end DSLR camera if possible. I am not doing any professional surveying just looking to improve our method for measuring our material stockpile. The current method is completed by taking several length, width, and height measurements to estimate volume.

Thanks!

Take a look at Rich GR series cameras.
Ugly camera, but it outperforms all other cameras in its class for image quality (when you shoot raw).

Thanks, I’ll check it out.
