Wide-angle camera device and survey system

Abstract

Problem: To provide a wide-angle camera device having a wide angle of view with less distortion in a peripheral portion of an image, and with less deterioration in resolution, and a survey system capable of acquiring an image including three-dimensional point cloud data. Resolution Means: A wide-angle camera device includes a plurality of cameras 2a and 2b. The cameras 2a and 2b respectively include imaging lens rear groups 10a and 10b as objective lenses, imaging lens front groups 11a and 11b as image forming lenses, prisms 6a and 6b that optically couple the imaging lens rear groups and the imaging lens front groups, and image sensors 8a and 8b that optically receive images formed by the imaging lens rear groups. The plurality of cameras are integrated by the prisms being bonded or brought into close contact with each other. Angles of view of adjacent ones of the cameras partially overlap each other. Entrance pupil positions Oa and Ob of the cameras are formed between the imaging lens front groups and the prisms, respectively. An intersection point of optical axes is a camera origin O.
