Disclosed is a dome camera, including a spherical surface part (A) positioned in the centre and an edge part (B) connected thereto, wherein an internal surface (3) and an external surface (4) of the edge part (B) are revolving surfaces, and a revolution axis thereof is parallel to that of the spherical surface part (A); the internal surface (3) is in a direction away from the spherical surface part (A) from a joint with the spherical surface part (A), with a monotonically increasing revolution radius; and focal power in both a meridian direction and a sagittal direction of the edge part (B) is the same as that of the spherical surface part (A). Since the dome cover is arranged such that the focal power in the meridian direction and the sagittal direction of the edge part (B) of the dome camera is the same as that of the spherical surface part (A), after light beams pass through the dome cover, light beams in the meridian direction and the sagittal direction of the dome cover can be focused on the same point, thereby eliminating astigmatism induced by the fact that the meridian direction and the sagittal direction cannot be focused on the same point in the conventional art, and providing favorable conditions for obtaining clear imaging.

A ball joint (10) arranged to couple an attachment part (12) to a base part (14) is provided. The ball joint (10) comprises: a ball (11, 71) associated with said attachment part (12) and provided with a groove (20, 70) having ends; a ball socket (13) formed in the base part (14) and provided with a recess (30); and a coupling element (40). The recess (30) and the groove (20, 70) are arranged such that a respective part of a coupling element (40) is allowed to move therein. The combined arrangement of the recess (30), the groove (20, 70), and the coupling element (40, 90) allows the ball (11, 71) to move from a first end position to a second end position by a rotational movement of at least 360 degrees. The recess (30) is larger than the part of the coupling element (40) located therein.

Disclosed herein is a rig for multi-camera photographing. The rig for multi-camera photographing includes a cover frame, a center base plate fixed and installed in a center line over the cover frame, and a left rotational movement plate and a right rotational movement plate disposed on the left and right sides of the center base plate and disposed in such a way as to rotatably move around rotational movement shafts protruded over the cover frame.
