Method and device for measuring keyboard keycap heights

The invention relates to a method and device for measuring the heights of keyboard keycaps. The method comprises the steps: a, scanning the surface, containing the keycaps, of a keyboard through a contourgraph, and obtaining the point cloud data of the surface of the keyboard; and b, calculating the keycap heights of the keyboard according to the point cloud data on the surface of the keyboard. The method and the device for measuring the heights of the keycaps of the keyboard can be used for automatically measuring the heights of the keycaps on various types of keyboards such as a PC (PersonalComputer), a notebook computer and the like, the height values of the keycaps can be accurately output only by scanning the keycaps of the keyboard once in sequence by using a contourgraph, and the whole process can be completely automatic without manual intervention; the problems of low keycap measurement efficiency, low precision and the like in the prior art are solved. 本发明一种测量键盘键帽高度的方法及装置，其中所述方法包括：a.利用轮廓仪对键盘含有键帽的表面进行
