Mobile terminal and method of establishing stereoscopic model through multipoint distance measurement

Abstract

The invention discloses a mobile terminal and a method of establishing a stereoscopic model through multipoint distance measurement, wherein the mobile terminal includes following units: a distance measurement module for focusing three different target objects in a geometric object and calculating the distances of the terminal to the three target objects respectively; a position module for establishing a coordinate system and monitoring orientation information of the terminal when the target objects is focused; a model establishing module for establishing the stereoscopic model of the object on the basis of the distance information and the corresponding orientation information; an image module for obtaining an image of the object; and a matching module for comparing the model with the image to determine whether the model is matched with the image or not, if true, a result that the model is successfully established is outputted, if false, a result that the model is mis-established is outputted with reminding information outputted to a user. Compared with a method in the prior art, the mobile terminal and the method can be used for establishing the stereoscopic model of the geometric object quickly and conveniently and determining whether the stereoscopic model is successfully established or not, thereby enhancing user experience.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a mobile terminal and a method for establishing a three-dimensional model by multi-point distance measurement. Background technique [0002] At present, for the drawing of an object or the establishment of a three-dimensional model, it is first necessary to measure its geometric size. The conventional measurement method of using a measuring ruler in cooperation with multiple people is time-consuming and laborious, and the use of multiple measurements to reduce errors further prolongs the measurement. It takes a lot of time to draw in the later period, such as making CAD drawings. This method of distance measurement can no longer meet the needs of the rapid development of the current society. [0003] In recent years, with the development of stereo (three-dimensional, 3D) technology, a stereo scanner is used to scan and measure the object to be drawn or modeled, and the p...

Problems solved by technology

Although this method can quickly and portablely establish the model of the indoor wall, this method not only needs to add a laser sensor to the electronic device, but also the number of sample points required to establish the model is determined by the customer, which may cause problems due to different samples. Insufficient points make complex wall model establishment inaccurate
