    摘要： The invention discloses a panel sorting device. The panel sorting device comprises a placement rack, an alignment device, and a classification robotic arm. The placement rack has multiple layers. Each layer of the placement rack places at least one panel according to the sequence with specification at corresponding position. The alignment device is used to obtain the positional deviation of the panel moved on a production line. Wherein, the classification robotic arm corrects the panel position based on the information of the positional deviation acquired by the alignment device, and places the panel in accordance with its sequence and specification to the corresponding position in the layer of the placement rack. To implement the panel sorting device of this present invention can quickly grab the panel and automatically sort according to the product's specifications. As a result, improve the efficiency of automated handling and production yield, and reduce costs and save installation space.

    摘要： A method for calibrating a computer-numerically-controlled machine can include capturing one or more images of at least a portion of the computer-numerically-controlled machine. The one or more images can be captured with at least one camera located inside an enclosure containing a material bed. A mapping relationship can be created which maps a pixel in the one or more images to a location within the computer-numerically controlled machine. The creation of the mapping relationship can include compensating for a difference in the one or more images relative to one or more physical parameters of the computer-numerically-controlled machine and/or a material positioned on the material bed. Related systems and/or articles of manufacture, including computer program products, are also provided.

    摘要： Described are machine vision systems and methods for simultaneous kinematic and hand-eye calibration. A machine vision system includes a robot or motion stage and a camera in communication with a control system. The control system is configured to move the robot or motion stage to poses, and for each pose: capture an image of calibration target features and robot joint angles or motion stage encoder counts. The control system is configured to obtain initial values for robot or motion stage calibration parameters, and determine initial values for hand-eye calibration parameters based on the initial values for the robot or motion stage calibration parameters, the image, and joint angles or encoder counts. The control system is configured to determine final values for the hand-eye calibration parameters and robot or motion stage calibration parameters by refining the hand-eye calibration parameters and robot or motion stage calibration parameters to minimize a cost function.
