Abstract
Provided are a magnetic bead-based detection method, a storage medium, and a detection device. The detection method includes: collecting a white light image of a to-be-detected solution, in which the to-be-detected solution is mixed with a to-be-detected sample and magnetic beads with a capture agent (S1); determining magnetic stripe regions in the white light image, and determining first magnetic bead regions based on the magnetic stripe regions (S2); selecting, by using a first neural network, second magnetic bead regions containing magnetic beads from the first magnetic bead regions, and obtaining a marker position of each of the magnetic beads (S3); and obtaining, by using a second neural network and based on each of the second magnetic bead regions, codes at code bits of a corresponding magnetic bead, and obtaining corresponding code information based on the codes of the code bits and the marker position of the magnetic bead (S4).
