Thermal Infrared Indoor Three-dimensional Modeling Method Based On The Fusion Of LIDAR Point Cloud And Ground Infrared Video Information

With the develop of the space measuring access to technology, Multiple Data Integration has become possible. Its integrated data collection is also increasingly being used in three-dimensional modeling. When the multi-sensor integrated system includes a laser radar scanner and thermal infrared camera, you can get the LiDAR point cloud data, and thermal infrared video data at the same time; How acquired point cloud data and thermal infrared data combined use the merits of the two data to generate a three-dimensional model with thermal infrared interior texture information, has become a research problem.Indoor dimensional modeling three-dimensional modeling is a hot issue, is widely used in the field of interior decoration and interior design. Combining the characteristics of LiDAR point cloud data and thermal infrared data, and the current modeling techniques more detailed discussion and analysis, A method of generating3D visualization model with the property of temperature is proposed. For the analysis of indoor places heat distribution, thermal anomalies hidden points, comfort and indoor spaces provide a technical means, so as energy saving, environmental protection office to provide geographic information technologies. The main work of this paper includes the following aspects(1) describes the programs and processes into the Chinese Academy of Surveying and Mapping integrated development of fusion LiDAR point cloud data and three-dimensional modeling system combines indoor thermal infrared video information;(2) for the thermal infrared video capture data, the heat infrared video sub-frame and stitching, identify high-temperature region by threshold segmentation method to provide technical support for the post-modeling textures;(3) for the acquisition of LiDAR point cloud data, we propose a constraint-based elevation points for indoor solution method cloud data, and point cloud filtering error exclusion and provide basic data for modeling;(4) for indoor thermal infrared three-dimensional modeling, proposes a combination of Geomagic studio12and3D Studio Max modeling methods;(5) designed a data collection program for three-dimensional modeling of indoor thermal infrared, and collecting the relevant experimental data, and experimental data processing, to complete the establishment of the model, to give the finished model thermal infrared textures, and analyze the experimental results prove that indoor mapping in terms of technology, you can replace the traditional mapping method, so that the technology has a faster data acquisition speed and efficient data processing speed, and therefore has a good indoor mapping the application prospect and broad space for development.
