摘要：Circular image block method has been developed for special photogrammetric close-range cases. Circular image block approach is not meant to substitute the current close-range photogrammetric network design methods, but simply to provide a new tool to be used with current methods. This method is beneficial in conditions where the traditional approach in network design problem meets its limitations; in cases when the photogrammetric network and camera stations cannot be around the object, but the imaging has to be done inside the object space. A new mathematical model had to be designed for the spherical imaging. However, this method is based on block of individual bundles of rays unlike the panoramic imaging. In this paper the method in real measuring tasks is evaluated in terms of accuracy and robustness. In order to evaluate the performance, a practical test was accomplished by measuring an object point set with varying object distances. Results are compared with reference data as well as with results of the simulated tests with similar test parameters. Discussion is given about the problem of initial values and the suitability of the method in an object reconstruction project
