    • A system and method of visual monitoring of a work implement (e.g., a welding torch) while a task is being performed (e.g., forming a welding joint) to train workers (e.g., apprentices, inexperienced workers) in proper welding technique, for example) and/or to evaluate the worker's use of a particular work implement (e.g., to determine if the welding torch was held in a desired relationship to the items being welded together, determine if the welding torch formed the joint at the current speed, etc.). In general, one or more cameras may acquire images of a target secured to and/or formed on the work implement. The images may be analyzed to provide feedback to the user, to be evaluated for weld integrity purposes; and/or may be used to compare the performance of a task (e.g., forming a welding joint) with a database of one or more profiles made by experienced and/or expert craftsmen.
    • 例如,在正在执行任务(例如,形成焊接接头)的情况下,对工件(例如,焊炬)进行视觉监控的系统和方法,以适当的焊接技术来训练工人(例如学徒,没有经验的工人) )和/或评估工人对特定工作工具的使用(例如,确定焊炬是否与焊接在一起的物品保持期望的关系,确定焊炬是否以当前速度形成接头等 。)。 通常,一个或多个相机可以获取固定到和/或形成在作业工具上的目标的图像。 可以分析图像以向用户提供反馈,以评估焊接完整性目的; 和/或可用于将任务(例如,形成焊接接头)的性能与由有经验的和/或专家技术人员制成的一个或多个简档的数据库进行比较。

    • The invention relates to motion tracking system (10) for tracking a movement of an object (P) in a three-dimensional space, the said object being composed of object portions having individual dimensions and mutual proportions and being sequentially interconnected by joints the system comprising orientation measurement units (S1, S3, . . . SN) for measuring data related to at least orientation of the object portions, wherein the orientation measurement units are arranged in positional and orientational relationships with respective object portions and having at least orientational parameters; a processor (3, 5) for receiving data from the orientation measurement units, the said processor comprising a module for deriving orientation and/or position information of the object portions using the received data and a calibration unit (7) arranged to calculate calibration values based on received data and pre-determined constraints for determining at least the mutual proportions of the object portions and orientational parameters of the orientation measurement units based on received data, pre-determined constrains and additional input data. The invention further relates to a method for tracking a movement of an object, a medical rehabilitation system and an animation system.
