Photogrammetry deals with acquiring imageries of the Earth’s surface and carrying out analysis with the data. Our team expertise in feature extraction, 3D modelling in the required LoD (Level of Detail) and reality capturing.
Photogrammetry is the science of obtaining reliable measurements and information about the physical properties of objects and their environment using photographs. This technique involves taking multiple overlapping images of an object or scene from different angles, and then processing these images to create a 3D model or map of the object or environment.
Photogrammetry has a wide range of applications, including land surveying, cartography, archaeology, geology, forestry, civil engineering, and many others. It is particularly useful in cases where direct measurements are difficult or impossible to obtain.
The process of photogrammetry involves various steps, including image acquisition, image preprocessing, image matching, 3D reconstruction, and data analysis. The accuracy and reliability of photogrammetric results depend on various factors such as camera calibration, image quality, and the availability of control points. With the advent of advanced digital cameras and software, photogrammetry has become more accessible and widely used in many fields.
Photogrammetry is a complex process that involves the use of specialized software and techniques to obtain accurate and reliable measurements and information from photographs. Here are some more details about the different stages involved in photogrammetry:
Image Acquisition: The first step in photogrammetry is to capture a series of overlapping photographs of the object or scene of interest using a camera or drone. The photographs should be taken from different angles to provide a complete coverage of the object or scene.
Image Preprocessing: The next step is to preprocess the images to remove any distortion, noise, or artifacts that might affect the accuracy of the results. This can involve correcting lens distortion, adjusting exposure, and enhancing image quality.
Image Matching: The images are then processed to identify corresponding points and features that can be used to create a 3D model. This is done by using algorithms that analyze the images and identify common points of interest.
3D Reconstruction: Once the corresponding points have been identified, the images are used to create a 3D model of the object or scene. This involves triangulating the position of each point in 3D space based on the corresponding points in multiple images.
Data Analysis: Finally, the 3D model is analyzed to obtain the desired measurements and information. This can involve measuring distances, volumes, areas, or angles, or extracting other features such as texture or color.
Photogrammetry can be done using various types of cameras, including traditional film cameras, digital cameras, or drones equipped with cameras. The accuracy of the results depends on several factors, such as the quality of the camera, the number of images taken, and the level of control and accuracy used in the image processing.
Applications of photogrammetry include creating topographic maps, modeling buildings and structures, creating digital elevation models, analyzing geological features, and monitoring environmental changes.
