[0029] Yield Measurement System

[0030] Certain aspects and features of the present disclosure relate to real-time yield measurement systems for harvesters (eg, combines). The yield measurement system can include a 3D sensor (eg, a stereo camera system) coupled to the elevator of the harvester. The 3D sensor is capable of detecting material (eg, sugar cane, potatoes, sugar beets, tomatoes, or other crops) passing over a portion of the elevator. The yield measurement system can process data from the 3D sensor to measure the net volume of material carried by the elevator in real time (eg, substantially while harvesting).

[0031] In some examples, the yield measurement system is capable of distinguishing the crop carried by the elevator from foreign material (eg, foreign material). The yield measurement system is capable of distinguishing crop from foreign matter by determining one or more characteristics (eg, size, color, shape, and texture) of the material carried by the el...

Abstract

A system is provided that can include a 3D sensor. The 3D sensor can be configured to detect an area of an elevator on a harvester. The 3D sensor can further be configured to transmit a first signal associated with the area. The system can also include a processing device in communication with the 3D sensor. The system can further include a memory device in which instructions executable by the processing device are stored for causing the processing device to receive the first signal and determine a volume of a material on the elevator based on the first signal.

Description

[0001] References to related applications [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 898,600, entitled "Video-Based Yield Measurement and Base Cutter Height Control for Harvester," and filed November 1, 2013, which is incorporated by reference in its entirety to this article. technical field [0003] The present disclosure generally relates to devices for use in agricultural operations. More specifically, but not in a limiting sense, the present disclosure relates to yield measurement and root cutter height control systems for harvesters. Background technique [0004] A harvester or combine can be used to collect material (eg, sugar cane, vegetables, crops, etc.) from a farm and load the material into a cart pulled by a tractor. Like many other types of farm operations, it may be desirable for a farm operator to know the yield of every part of the farm. This can allow farm operators to optimize the farming process.
