    • The present invention provides a method and apparatus for accurately positioning a robotic pool-playing device. The system comprises a computer controlled robotic positioning device, such as a gantry robot, that can position a cue over the pool table and place a shot. A global camera is mounted on the ceiling looking down at the table, and the acquired images are transmitted to the computer for analysis to determine the identity and locations of the balls within the table coordinate reference frame. The computer also automatically determines which ball to strike. An aspect of the invention is the use of a local camera, mounted on or near the robotic end-effector in a fixed relationship with the cue, to improve the positioning error of the robotic device prior to placing a shot. By comparing the ball locations perceived from the vantage of the local camera with the known ball locations determined from the global camera image, the invention can calculate the acquired robotic positioning error, which can then be corrected for prior to placing the shot.
    • 本发明提供一种用于精确地定位机器人游泳池装置的方法和装置。 该系统包括计算机控制的机器人定位装置,例如龙门架机器人,其可以将提示定位在台球台上并放置一个镜头。 将全景照相机安装在天花板上俯视桌子上,并将获取的图像传送到计算机进行分析,以确定球在坐标参考坐标系中的身份和位置。 计算机还自动确定要击球的位置。 本发明的一个方面是使用安装在机器人末端执行机构上或附近的局部照相机,其与提示具有固定的关系,以在放置镜头之前改善机器人装置的定位误差。 通过将从本地摄像机的有利位置感知的球位置与从全局摄像机图像确定的已知球位置进行比较,本发明可以计算获得的机器人定位误差,然后可以在放置镜头之前对其进行校正。
