A system and method for estimating livestock weight is described. Embodiments of the system can include a computing device and a three-dimensional tag configured to be secured to an animal. One or more images of an animal, including the three-dimensional tag, can be processed to take various measurements of the animal. A scaling factor for the measurements can be based on the three-dimensional tag. After the measurement are calibrated, a weight of the animal can be estimated based on the calibrated measurements.

An electronic scale includes: a scale body that has a top surface provided with a weighing tray on which an object to be weighed is to be laid and a display portion which displays a weight of the object to be weighed; and a lid member that is capable of closing the top surface of the scale body and that is capable of opening and closing. A camera that images the top surface of the scale body including the weighing tray and the display portion is provided on the lid member. Alternatively, the camera is provided on the top surface of the scale body and the lid member includes reflection means that reflects an image of the top surface of the scale body including the weighing tray and the display portion toward the camera when the lid member opens, on a surface of the lid member that faces the scale body. The electronic scale is capable of simultaneously imaging the object to be weighed and the displayed weight of the same and eliminates need for a special support structure to support the camera for imaging, and the top surface of the scale body can be closed when the electronic scale is not in use.
