What is stereophotogrammetry used for?

Stereophotogrammetry is a technique used for combining two photographs taken from different angles to create a three-dimensional representation of the subject. This method utilizes the principles of stereoscopy, allowing the viewer to perceive depth in the produced images. By capturing images from slightly different vantage points, it can accurately represent the spatial relationships and shapes of objects or landscapes, making it particularly useful in creating digital stereo images.

This technology has applications across various fields, including surveying, mapping, and even virtual reality, where understanding three-dimensional space is crucial. As a result, the correct understanding of stereophotogrammetry aligns with option B, emphasizing its role in synthesizing depth perception from paired photographs. The other options, while relevant to different technologies and practices, do not accurately describe the primary function of stereophotogrammetry.
