The present invention relates to a weld bead inspection apparatus and, more specifically, to a weld bead inspection apparatus capable of precisely inspecting a weld bead. The present invention relates to the weld bead inspection apparatus for inspecting whether a weld bead (20) on a pipe (10) is defective, and disclosed is the weld bead inspection apparatus comprising: a housing (100) encompassing the pipe (10) so as to cover the weld bead (20), and forming a closed inspection space (S) therein; an inspection means (200) provided in the housing (100) so as to confirm the state of the weld bead (20) in the inspection space (S); and a defect determination unit for determining whether the weld bead (20) is defective on the basis of the state of the weld bead (20), having been confirmed through the inspection means (200).

An imaging system is for recording images of a bearing raceway and includes a platform having a surface sized to receive the bearing ring and an optical imager having a lens. A positioner secures the optical imager or a reflector oriented to reflect light to the optical imager lens and locates the optical imager lens or the reflector axially between first and second axial ends of the raceway and facing generally toward the raceway. A motor rotates the platform or the positioner relative to the other one of the platform and the positioner. A processor operates the optical imager and the motor such that the optical imager takes a series of images about the entire perimeter of the bearing raceway. The processor also indexes each image to a separate one of a plurality of arcuate segments of the raceway and constructs a panoramic image of the raceway.

A self-calibrating inspection system includes an inspection device adapted to visually inspect or measure an article placed on a carrier, and a motion actuator moving the inspection device along a predetermined motion trajectory relative to the carrier and the article placed thereon. A correction member of the system is fixedly positioned with respect to the carrier. A distance sensor is fixedly positioned relative to the inspection device and adapted to sense a first spacing between the distance sensor and the correction member during the movement of the inspection device by the motion actuator. A controller communicates with the motion actuator and the distance sensor for determining a deviation between an actual motion trajectory of the inspection device moved by the motion actuator and the predetermined motion trajectory based on the first spacing, and to control the motion actuator based on the deviation to move the inspection device along a path substantially consistent with the predetermined motion trajectory.

An artificial neural network-based method for detecting a surface type of an object includes: receiving a plurality of object images, wherein a plurality of spectra of the plurality of object images are different from one another and each of the object images has one of the spectra; transforming each object image into a matrix, wherein the matrix has a channel value that represents the spectrum of the corresponding object image; and executing a deep learning program by using the matrices to build a predictive model for identifying a target surface type of the object. Accordingly, the speed of identifying the target surface type of the object is increased, further improving the product yield of the object.
