Abstract. The ancient architectural plaque is a unique cultural heritage of the Chinese traditional culture. It is called the "soul of ancient architecture" and has important historical and artistic value. Due to its small size and large quantity, the preservation status is not optimistic, and it is urgent to carry out rescue protection. It is especially necessary to complete its digital information collection first. The basic images used in photogrammetry are usually taken by professional cameras. With the continuous development of technology, the shooting ability of mobile phones is constantly increasing. The method of 3D reconstruction of plaque of ancient buildings by common mobile phone cameras is studied through experiments. Several common mobile phones were selected to collect images of ancient building plaques from different acquisition distances and 3D reconstruction experiments were carried out. The results of accuracy evaluation showed that the information of ancient architectural collected by common mobile phone cameras within the suitable acquisition range can meet the accuracy of 3D reconstruction. Requirements. In addition, the image control point measurement is replaced by a standard card. The experimental results show that the size of the model can be controlled by using the card constraint. The method can utilize the commonly used camera mobile phone to efficiently obtain the image of the ancient buildings distributed in various places and carry out three-dimensional reconstruction, thereby satisfying the urgent requirement of the urgent need for protection of the ancient buildings.
