The invention discloses a three-eye depth obtaining camera with adjustable optical axes. Two independent camera modules are arranged on left and right sides, an active depth camera is arranged at the upper side, the active depth camera can adjust a pitch angle and a rotation angle, can be driven by a steering engine to synchronously rotate and can automatically output the angle, the left and right cameras are matched through a screw rod axle hole, and another coded disc is used for indicating an included angle between two optical axes. According to the three-eye depth obtaining camera disclosed by the invention, the non-parallel optical axes are applied to depth information calculation, and by means of the adjustable optical axes, a visual angle obtained from the depth information becomes a value that can be adjusted according to the actual condition. Moreover, as the active depth camera is additionally arranged, the binocular distance measurement information is combined with the distance measurement information of the active depth camera, and thus the final depth data can be better expressed.
