Application of 3D laser and oblique photography technology in cultural relics and buildings

With the development and progress of the times, people have paid more attention to cultural relics. For the protection of cultural relics, the emergence of various emerging technologies has greatly improved production efficiency compared with traditional measurement technologies. Based on handheld laser scanning technology, ground 3D laser technology and Unmanned aerial vehicle (UAV) oblique photography technology, two cultural relics buildings were digitized and archived. The 3D data of cultural relics buildings were obtained by using these three technologies. The method is helpful to accurately preserve the size and size information of cultural relics, so that the subsequent restoration and protection of cultural relics have high-precision sample information for reference. The study also makes a 3D model into a web page to introduce and promote its culture, which helps to strengthen people 's awareness and understanding of the cultural relics.
