What does a reseau camera do?

A reseau camera is specifically designed to enhance the accuracy of photogrammetric measurements. It achieves this through the use of a superimposed grid, which helps in minimizing distortion in the captured images. This grid allows surveyors and photogrammetrists to more precisely relate measurements from photographs to real-world coordinates, thus improving the overall quality of the data collected during aerial surveys.

While there are cameras that perform functions such as recording images automatically, calibrating lenses, or controlling the camera shutter, these do not encapsulate what a reseau camera fundamentally accomplishes. The primary purpose of a reseau camera revolves around the enhancement of measurement accuracy by providing a known reference grid on the captured images, which is essential for engineering, mapping, and surveying tasks. This makes its function of superimposing a grid vital for producing reliable and distortion-free measurements.
