What is the basic principle of photogrammetry?

Photogrammetry Training with UrbanPro.com As an experienced tutor registered on UrbanPro.com specializing in Photogrammetry, I'm delighted to provide you with insights into the basic principles of Photogrammetry. Introduction to Photogrammetry Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring, and interpreting images. Basic Principle of Photogrammetry Photogrammetry relies on the fundamental principle of triangulation, which involves the measurement of overlapping images to determine the geometric properties of objects. The key steps in the basic principle are: Image Acquisition: Collection of overlapping aerial or terrestrial photographs of the target area. Ensures adequate coverage and sufficient overlap for accurate measurements. Image Orientation: Determining the spatial relationship between the images. Involves establishing ground control points to anchor the images to real-world coordinates. Triangulation: Utilizes the overlapping images to create a network of triangles. Enables the calculation of precise three-dimensional coordinates of points on the object or terrain. Point Cloud Generation: Based on the triangulated information, a dense set of points is generated, forming a point cloud. Represents the surface of the object in three-dimensional space. Digital Surface Model (DSM) and Digital Terrain Model (DTM) Creation: DSM represents the surface, including any elevated features. DTM represents the bare earth or terrain without any above-ground features. Data Analysis and Interpretation: Analyzing the point cloud and derived models for various applications. Extracting valuable information such as topography, elevation, and object dimensions.
