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; determining whether a first reflecting light resulting from the first laser beam reflected by the first reflecting surface is received; 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; 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; 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.
