近年来，文化遗产遗址和文物的三维(3D)扫描和建模显着增加。为了保存、重建、研究和博物馆展览等目的，对各种各样的物品进行了扫描和建模，例如小陶器、雕像、建筑物和大片考古遗址。由于要扫描的对象的大小范围以及用于扫描和建模的目标的不同，已经测试和使用了许多方法和选项。因此，显然没有一种方法适用于记录每一种文化遗产主题，因此对利用多种技术的混合方法的需求很大。激光扫描可以生成创建高分辨率几何模型所需的密集3D点云数据，尽管颜色信息的质量有时会低于要求。另一项技术是数字摄影测量，如果原始图像有足够的像素和3D模型，就可以产生高分辨率的纹理。毫无疑问，这两种技术在创建高质量的3D记录和演示方面可以相辅相成。本文从建立准确、富有表现力的模型和高效的数据处理的角度，对激光扫描和摄影测量技术及其在文化遗产数字化记录中的联合应用进行了比较和评价。这里使用的数据来自我们2002年对土耳其西南海岸外的杰米勒岛上的拜占庭遗址进行的实验性3D测量。*通讯作者。
Three-dimensional (3D) scanning and modeling of sites and artifacts of cultural heritage have increased remarkably in recent years. A wide variety of objects, e.g., small pieces of pottery, statues, buildings, and large areas of archaeological sites, have been scanned and modeled for such purposes as preservation, reconstruction, study, and museum exhibitions. Due to the range in size of the objects to be scanned and differences in the objectives for scanning and modeling, many approaches and options have been tested and used. As a result, it is clear that there is no single method that is applicable to recording every subject of cultural heritage and hence there is a strong demand for a hybrid method that exploits several technologies. Laser scanning can produce the dense 3D point-cloud data that is required to create high-resolution geometric models, although the quality of color information is sometimes lower than required. Another technology, digital photogrammetry, can produce high-resolution textures, if the original images have sufficient pixels, and 3D models. There is no doubt that these two technologies can supplement each other in creating high-quality 3D recordings and presentations. In this paper, we report a comparison and evaluation of laser scanning and photogrammetry and their combined use to digitally record cultural heritage objects from the point of view of producing accurate and expressive models and efficient data processing. The data used here was obtained from our experimental 3D measurement of Byzantine ruins on Gemiler Island, off the southwest coast of Turkey, in 2002. * Corresponding author.
