Description

Technical Field

[0001] This application relates to the technical field of equipment for detecting grain loss, and more particularly to a visual camera bracket for grain detection. Background Technology

[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] Visual inspection technology, utilizing high-resolution cameras and advanced image processing algorithms, can accurately identify and classify the appearance characteristics of grains. It can distinguish different varieties of grains and identify features such as shape, size, and color, thereby enabling rapid quality assessment. This technology effectively improves the accuracy of grain classification, reduces errors from manual classification, and automates the inspection process. By rapidly acquiring and analyzing grain images through a machine vision system, it not only significantly improves inspection efficiency but also ensures the consistency and reliability of inspection results, while reducing labor costs.

[0004] Visual inspection applications rely on fixed camera mounts. A well-positioned and angled camera mount results in accurate images; otherwise, repeated shooting is necessary until the required images for visual inspection are obtained. For grain inspection, multi-angle, all-around, and blind-spot-free imaging is required to accurately acquire grain information. A single viewing angle is insufficient. Adding multiple vision cameras increases costs and can obstruct grain transport in practice. Finally, camera placement inevitably involves errors, requiring adjustments during application. Ordinary vision camera mounts are often inadequate for these requirements.

[0005] Therefore, it is necessary to provide a visual camera holder for grain detection to solve the above-mentioned technical problems. Summary of the Invention
