Height measuring apparatus and method thereof

摘要

A height measuring apparatus and a method thereof are disclosed. The disclosed method is suitable for an indoor environment. The disclosed method comprises emitting a first laser to a ceil via a first light path, determining whether a first reflective light corresponding to the first laser is received, emitting a second laser to an object via a second light path reflected by the ceil, determining whether a second reflective light corresponding to the second laser is received, calculating a first length according to a first data corresponding to the first reflective light, calculating a second length according to a second data corresponding to the second reflective light, and calculating an object height of the object according to the first length and the second length.

1. A method for measuring height applicable for an environment with a first reflecting surface, the method comprises:
emitting a first laser beam along a first light path from a baseboard; determining whether a first reflecting light resulting from the first laser beam reflected by the first reflecting surface is received, wherein the first reflecting light is reflected only once by the first reflecting surface; calculating a first length according to a first piece of data corresponding to the first reflecting light when the first reflecting light is received; emitting a second laser beam along a second light path from the baseboard; determining whether a second reflecting light resulting from the second laser beam reflected by both of the first reflecting surface and an object under test is received, the object under test is carried on a top surface of the baseboard; calculating a second length according to a second piece of data corresponding to the second reflecting light when the second reflecting light is received; and calculating a height of the object under test at least according to the first length and the second length; wherein the object under test is disposed between the first reflecting surface and the top surface of the baseboard.
