AI Technical Summary

Technical Problem

In existing technologies, the rolling and flipping of ore during transportation makes it difficult to accurately register X-ray images and visible light images, resulting in low accuracy in ore identification and sorting.

Method used

By acquiring transmission and color sorting images, the first contour is determined based on the transmission image and mapped to the color sorting image. The foreground and background regions are divided, candidate sub-regions are introduced and merged to determine the target region. Gray-scale binarization and centroid position are used to correct the ore contour offset, thus establishing an accurate target region identification method.

Benefits of technology

It achieves high-precision matching between transmission images and color sorting images under ore pose changes, ensuring the integrity of ore contour and color information, improving the accuracy of ore identification and sorting, and reducing the probability of misjudgment and missed judgment.

Abstract

本公开涉及分选设备技术领域,具体涉及一种目标区域识别方法、图像采集系统及分选机。目标区域识别方法包括:获取对应同一目标的透射图像和色选图像,透射图像通过检测装置基于X射线采集、色选图像通过色选装置采集;基于透射图像,确定对应目标的第一轮廓;基于第一轮廓,确定色选图像中的第二轮廓;基于第二轮廓,在色选图像中,确定前景区域与背景区域;确定背景区域中的候选子区域;基于候选子区域与前景区域,确定色选图像的目标区域。根据本公开能够实现透射图像与色选图像轮廓的准确匹配,矿石位姿改变的情况下也能够实现高效、高精度的图像匹配,准确确定目标区域。保证目标区域内的矿石信息清晰明确,对矿石的识别有更高的准确性。
