[0002] Wheat is a widely grown crop. Its seeds are a kind of cereal and a staple food worldwide. Wheat kernels are mainly used to make flour, while wheat husks can be used as feed. The shape of wheat kernels is an important criterion for measuring the quality of the wheat variety and finished product. Therefore, it is often necessary to measure the shape of the produced wheat kernels.

[0003] In the prior art, for high-precision measurement needs, optical detection equipment is used to conduct targeted detection of the shape of each wheat grain, but this solution has high equipment cost, is difficult to popularize, and takes a long time to detect a large number of samples. Alternatively, a mechanical measurement solution is used. Mechanical measurement generally directly measures the length and diameter of the wheat grain shape with a ruler, but due to the small size of wheat grains, whether it is independent measurement or multi-grain arrangement measurement, it will produce high operational difficulty due to the small volume, resulting in cumbersome measurement steps and long measurement time. Especially for the measurement of length, it is very easy to be unable to accurately measure the central axis due to the tilt of the wheat grains, and the measurement results are prone to large errors.
