Description

Camera component and shooting equipment for calibrating photo position

Technical Field

The invention relates to the field of cameras, in particular to a camera component and shooting equipment for calibrating the position of a picture.

Background

With the increase of the degree of digitization, especially for some professionals with special needs, the requirement for photos is higher, wherein a very important item of data, namely the orientation information of the photos. For example, in field geological work, for some specific structures and geological phenomena, the orientation information is a very important hand of information. However, in today's field work, the framing of these geological phenomena still requires multiple procedures or even two or three people to coordinate: and measuring the orientation of the picture by using a compass in the photographing process and manually recording the orientation. The efficiency of the operation is greatly reduced and some measurement deviations may result due to multiprocessing.
