Pix4D is an advanced photogrammetry software, which is widely used in the field of image processing taken by unmanned aerial vehicles.

Photogrammetry refers to the technology of measuring the shape, size and spatial position of the target by combining camera and film. Since 1839, when Nips and Dale invented photography, photogrammetry has a history of 170 years.

Photogrammetry is to obtain the shape, size, position, characteristics and their relationship of objects by processing the photos obtained by optical cameras. The main task of photogrammetry is to make topographic maps of various scales, establish topographic databases, provide spatial basic data for various geographic information systems, land information systems and various projects, and serve non-topographic fields, such as industry, architecture, biology, medicine and archaeology.
