Line Features

To solve existing problems in modeling facade of building merely with point feature based on close-range images , a new method for modeling building facade under line feature constraint is proposed in this paper. Firstly, Camera parameters and sparse spatial point clouds data were restored using the SFM , and 3D dense point clouds were generated with MVS; Secondly, the line features were detected based on the gradient direction , those detected line features were fit considering directions and lengths , then line features were matched under multiple types of constraints and extracted from multi-image sequence. At last, final facade mesh of a building was triangulated with point cloud and line features. The experiment shows that this method can effectively reconstruct the geometric facade of buildings using the advantages of combining point and line features of the close - range image sequence，especially in restoring the contour information of the facade of buildings.

Cultural Relics

The theory and characteristics of the multi-baseline digital close-range photogrametry were discussed to be used in cultural relics preservation. Take the 3D reconstruction project of the Yu Shan the 5th mural tomb in Ji-an as an example, two methods were put forward to measure the control points of the image without any harm to the object. Also, Tricolor cool tone electron energy conservation lamp was used to meet the strict color control of the mural images. Engineering tests show that the methods put forward could greatly reduce the field work and labor intensity with the characteristics of high accuracy, automation and efficiency. Production efficiency is improved as well. The precision of mapping and image texture satisfies the requirements of cultural relics preservation. In addition, how to manage and index such data through database technology needs further study.
