The invention discloses a vision-based image-text defect detection method, and relates to the field of computer vision recognition. According to the method, a color high-definition industrial camera and a lens are adopted for photographing printed matters within the size, standard templates are manufactured for qualified products, feature information of the templates is extracted, and then printing samples placed in any posture are photographed and compared; according to the algorithm, high-precision multi-scale registration correction is automatically performed on sample images and template images in an image comparison process, so that complex work such as high-precision placement of a single printed matter by using a jig or manual correction of a rotation angle at present is omitted, and deformation generated by the samples in different placement postures can be automatically corrected; and finally, small image-text printing defects can be identified. Not only can characters and symbols be processed, but also various printing contents containing images, characters and forms can be processed, various defects can be better detected, and the high-standard quality detection requirements of the fields of 3C, food, medicine and the like on printed matters are met.

The invention relates to the technical field of file arrangement, in particular to a file sorting device. The file sorting device comprises a visual recognition device, a preset arrangement device, a sorting and pressing device, a positioning and pushing-aside device and a file pushing device, wherein the preset arrangement device comprises a first blocking piece, a second blocking piece and a spring; the file pushing device comprises a first driver and a pushing piece, a third blocking piece is connected to the pushing piece in a sliding mode, the second blocking piece and the third blocking piece are used for clamping and fixing files to be sorted, and the pushing piece is provided with a clamping position where the files to be sorted can be conveniently clamped; the sorting and pressing device is used for clamping and fixing the sorted files; and the positioning and pushing-aside device is used for moving to the corresponding positions of the sorted files according to the numbers and the thicknesses obtained by the visual recognition device and pushing aside the two sorted files to form a containing space, and the first driver drives the pushing piece to drive the files to be sorted to move into the corresponding containing space. The file sorting device effectively solves the technical problems that the sorting width is limited and the surface is uneven during file grabbing in an existing file sorting device.

The invention discloses an intelligent carrying device based on visual identification. The intelligent carrying device comprises a rotating mechanism, a connecting sleeve, a clamping mechanism, a hoisting mechanism and a camera. When an image shot by the camera shows that hoisting holes are symmetrically distributed on the two sides of the image, the carrying device uses the clamping function of the clamping mechanism; and when the shot image shows that two hoisting rings or four hoisting rings are symmetrically and evenly distributed on the integral central surface of the image, the carrying device is hoisted by steel wire rope hoisting hooks of the hoisting mechanism. By means of the device, corresponding clamping and hoisting functions can be achieved for different kinds of materials with hoisting rings and flanges with hoisting holes in the two sides, maximum dense storage of a warehouse is achieved, meanwhile, manual steps are reduced, and the automation level of the warehouse is improved.
