Indoor Information Modeling And Precision Analysis Based On Kinect Depth Sensor

3D reconstruction technology refers to the use of digital means to achievethe 3D reproduction of information truly in a computer.With the rapidly development of 3D reconstruction technique,interior 3D reconstruction is becoming a research focus.The modeling equipment of traditional methods mostly operate complicatedly and relatively expensive,these factors make it is not Convenientto fast reconstruction in relatively complex indoor environment.Therefore,how to achieve the low-cost,easy operating and highly accurate 3D information reconstruction of interior has great significance.Considering the existing problemsof traditional modeling methods,This paper presents a spatial method of interior 3D information reconstruction based on Microsoft Kinect depth sensor.and in troduced how to achieve the depth image data acquisition,conversion between the coordinate system in the process of 3D information reconstruction reference to the characteristics of Microsoft kinect depth sensor.In order to verify the impact of model accuracy of this method acquired by geometric distance,indoor lighting and a scan length,this paper presents relevant comparative experiments.In this paper simultaneously,point cloud model obtained through 3D laser scanning technology was used to compare and then the accuracy evaluation of model reconstructed through Micrisoft Kinect was given.
