Method for simulating real environment after floor in room is changed

Abstract

The invention discloses a method for simulating real environment after floor in a room is changed. The method comprises: (1) realizing preliminary establishing of a three-dimensional model in a room;(2) through an illumination intensity detection apparatus, detecting illumination intensity F1, F2, and F3 of positions of a window, a door, and a three-dimensional space tracking positioner, throughthe F1, F2, and F3, calculating a function relation corresponding to illumination intensity and distances; inputting the function relation into a three-dimensional model establishing system, to obtaina light intensity arrangement method; illumination intensity of a certain spatial point being sum of illumination intensity of light on the position and illumination intensity of natural light of a window position on the position; (3) obtaining a floor picture and specifications and a corresponding region segmentation method; (4) when a floor which needs showing is selected, using the region segmentation method corresponding to the floor specification, and filling the floor picture on a plane where the floor is in. The method can preferably realize real simulation of indoor illumination angles and intensity.

Description

technical field [0001] The invention belongs to a simulation method, in particular to a method for simulating the real environment after floor replacement in a room. Background technique [0002] The indoor three-dimensional positioning technology in the prior art, when it is applied to model building, usually uses a camera to capture images, and then simulates the construction model through the number of frames of the image. The algorithm is complex, and the equipment used to build the model is expensive and accurate The accuracy is not high, especially for different lighting conditions, the simulation effect of the indoor environment is poor. [0003] When the model established by the method and device in the prior art is displayed on the floor, wallpaper, etc., due to reasons such as light angle and intensity, there is a great difference between the actual construction effect drawing and the displayed picture, which may easily lead to consumption. Unsatisfactory situatio...
