摘要： Disclosed are a method, a device and a system for improving system accuracy of an X-Y motion platform, and the method includes: taking a picture of a preset calibration board synchronously as a controlled equipment on an X-Y motion platform moves, and analyzing the picture to obtain pixel coordinates of a calibration point in the picture, where the preset calibration board is taken as a reference; acquiring actual coordinates of the calibration point on the calibration board, and calculating actual position coordinates of the controlled equipment on the X-Y motion platform from the actual coordinates and the pixel coordinates of the calibration point; and adjusting a motion control system of the X-Y motion platform according to the actual position coordinates, to control the motion of the X-Y motion platform to perform motion compensation for the controlled equipment. With the technical solution of the invention, the system accuracy can be improved, and the requirements for assembly and device selection can be reduced.

摘要： The present invention relates to a compact motorized rotational stage for microscopy applications and control methods for automated sample orientation/rotation. The rotational stage includes a motor, a rotational motion transmission mechanism, and a rotating sample holder for accommodating a holding device such as glass slides/Petri dishes of different sizes. Mouse embryos are used as an example to explain the control methods. A pattern recognition utility was developed for identifying mouse embryo structures. The transformation between the holding device rotational coordinate frame and the translational positioning stage coordinate frame is calibrated during image-based visual servo control. The polar body of an embryo is oriented through purely image-based visual servo control or through coordinate transformation and closed-loop position control.

摘要： A plasma cutting device performs cutting in a plurality of stages. In a first cutting sub-process, a manufactured product is cut out from a base material upon a stage according to an NC program. Next, images of respective regions in the vicinities of proper positions at two corner points of the manufactured product which has been cut out are photographed by an image sensor, the actual positions of these two corner points of the manufactured product are detected from these images which have been photographed, and the translation distances and the rotational angle between the actual positions which have been detected and the proper positions are calculated. The NC program is corrected. And, in a subsequent cutting sub-process, additional cutting for beveling is carried out upon cutting surfaces at the outer circumference of the manufactured product, according to the corrected NC program.
