Method for removing and detecting iron foreign matters in iron ore belt conveying process

The invention discloses an elimination and detection method for eliminating iron foreign matters doped in an iron ore production belt transportation process, which comprises the following steps: acquiring calibration data of special foreign matters in different scenes, and establishing a positive and negative sample library; an image collection module is used for collecting images of materials borne by the belt within a preset range of the iron ore belt conveying scene in real time, the obtained images are compared with the foreign matter in the positive and negative sample libraries and a normal scene, and a foreign matter similarity value is output; the obtained image is compared with a system preset value, if the image meets a foreign matter preset value, a foreign matter removing process is started, a mechanical pushing hand is used for horizontally pushing a foreign matter area in the vertical direction of belt conveying to remove foreign matter, and a mechanical arm can be used for clamping and removing
