Definition

Automatic data acquisition is the extraction of information from images, relevant for a given application, by means of a computer. Photogrammetric image processing is divided into two aspects, i.e., the geometric/radiometric image evaluation and image analysis. Geometric/radiometric image evaluation comprises image orientation, the derivation of geometric surface descriptions and orthoprojection. Image analysis contains the extraction and description of three-dimensional (3D) objects. A strict separation of both areas is possible neither for manual nor for automatic photogrammetric image processing.

Historical Background

In the past, geometric/radiometric image evaluation and image analysis were two clearly separated steps in the photogrammetric processing chain. Using analogue imagery, automationwas understood as a supporting measure for a human operator, e.g., by driving the cursor...
