Architecture physical data rapid three-dimensional sampling method

Abstract

The present invention discloses a quick three-dimensional sampling method for physical data of a building. The present invention adopts a miniature unmanned aircraft to load corresponding types of sensing devices, data recording devices and information returning devices, etc., so as to acquire the physical data (intensity of sound, audio, temperature, humidity, illuminance, light color, gas components, electromagnetic field intensity, air-ion concentration, radiation strength, etc.) and carry out round trip flight in space and continuously acquire the physical data at each point of the path, and position the miniature aircraft by a photogrametry technology. The method concretely comprises the steps of: selection of the miniature unmanned aircraft for indoor flight, selection of sensing devices or sensors for sampling the physical data of the building, establishment of a system synchronous clock, sampling of the physical data of the building and accurate spatial positioning for the sampling points by a close-range photogrammetry method. Since the aircraft is fast in moving speed and is not restricted by the ground movement condition, the isochronism of the data can be ensured even if the number of the spatial sampling is largely increased than that of the ground operations.

Description

Fast 3D Sampling Method for Building Physics Data 【Technical field】: The invention belongs to the technical field of buildings, and in particular relates to the collection of various physical data in building rooms. 【Background technique】: "Physical data" at any position in the building interior space refers to: sound intensity, sound frequency, temperature, humidity, illuminance, light color, and gas composition at a certain point in the space. These data are important research data in the field of architectural technology. For example, when a concert hall whose main part has just been completed is preparing for interior decoration, it is necessary to measure the sound distribution in the space for analysis, and then accurately design sound absorption. The type, area, location, etc. of the material; in addition, the intensity value of the light in the stadium and the uniformity of the light distribution are related to the effect of the game and watching the game, so sampl...
