Abstract. The use of AI in semantic segmentation has grown significantly recent years, aided by developments computing power and the availability annotated images for training data. However, context close-range photogrammetry, although working with 2D images, is still used mostly 3D point cloud purposes. In this paper, we propose a simple method to apply such methods close range photogrammetry ...

In order to solve the restriction of the two common calibration modes applied in digital close-range industrial photogrammetry, a new camera calibration method based on orientation points was proposed. Firstly, image sequences were obtained applying a calibration plate with five orientation points. The ellipse detection criteria were applied to eliminate the redundant information from images af...
