The present invention relates to a fuel pellet boundary dimension and apparent defect detection device and method. The detection device comprises a mechanical device and two sets of image acquisition devices which are arranged inside a glove box and an image processing system arranged outside the glove box, and measures the diameter and the surface integrity of a fuel pellet automatically via the automatic ranking, feeding, transporting, rotating and discharging operations. The two sets of visual light image acquisition devices acquire the parameters of a cylindrical surface and two end faces of the fuel pellet respectively, and send the acquired complete cylindrical surface and end face images to the image processing system when the fuel pellet arrives at the detection positions orderly, and the image processing system analyzes, processes and determines the results automatically to sort the good and bad materials. The detection method comprises processing the boundary dimension images, the side surface image
