The invention discloses an intelligent positioning method for small ceramic files based on multi-feature fusion. The intelligent positioning method comprises the steps of S1, image acquisition; S2, image preprocessing; S3, feature extraction, S4, image target determination; and S5, ceramic file positioning. In the step of image acquisition, an image is acquired through a high-speed linear array CCD camera. In the step of image preprocessing, gray processing is firstly performed on the image, then filtering and denoising processing is carried out, the filtered image is segmented by adopting an edge detection algorithm, the profile of the small ceramic tile is extracted, and then a profile diagram of the ceramic tile is acquired. In the step of feature extraction, corresponding primitive features are generated based on geometric features of the ceramic tile profile in the profile diagram in the step S2; and a logical AND operation is performed by using a filtered image and the profile mask diagram in the step S2, transferring an operation result diagram into an HSV color space, and color features are generated; and combination features are generated according to the primitive features and the color features. The intelligent positioning method realizes high-precision positioning for the small ceramic tiles at a large FOV (Field of View), thereby providing accurate positioning data for visual inspection and robot grasping. In addition, multiple segmentation units can operate concurrently in a multi-threaded system, and the real-time performance of the system is improved.
