Photogrammetry has been a key discipline in the development of cartography and geospatial analysis. With the evolution of technology, methods have evolved from analytical systems based on mathematical models to digital techniques using artificial intelligence and advanced image processing.
At Aerolasera leading photogrammetry solutions company, applies both the principles of analytical photogrammetry and the advantages of digital photogrammetry to deliver the most accurate geospatial models. In this article, we will explore the differences between the two methodologies, their impact on different industries and how Aerolaser optimizes projects with cutting-edge technology.
What is Analytical and Digital Photogrammetry?
Photogrammetry is based on obtaining three-dimensional information from two-dimensional images. Its evolution has given rise to two main approaches:
Analytical Photogrammetry
It is a method that combines photography with mathematical models to calculate positions and dimensions in space. It emerged with the automation of manual processes, allowing the accurate interpretation of images captured with aerial cameras.
Digital Photogrammetry
It is based on the use of advanced software to process images and generate three-dimensional terrain models more quickly and accurately. Thanks to artificial intelligence algorithms, processing is more efficient and large volumes of data can be handled in less time.
Differences between Analytical and Digital Photogrammetry
