Abstract: A target detection method, device, an electronic apparatus, and a storage medium are provided, which are related to a field of computer vision technology. The specific implementation includes: determining at least one first image from multiple images, wherein a candidate target is contained in respective first images; acquiring confidence degrees of the candidate target in the respective first images; calculating an appearance probability of the candidate target according to weights and the confidence degrees of the respective first image; and determining the candidate target as a final target, in a case that the appearance probability meets a first preset condition. A candidate target may be comprehensively determined by using a detection result of multiple images, thereby determining a detected final target, and improving the detection accuracy of the final target.
