The invention discloses a hyperbolic concave refractive and reflective panorama camera and a making method and application thereof. The panorama camera comprises a base and a common perspective camera which can be arranged on a vehicular platform; a hyperbolic concave reflector for reflecting pavement images is arranged in front of a lens of the common perspective camera; the optical axis of the hyperbolic concave reflector is superposed with the common perspective camera; and the hyperbolic concave reflector is connected to the base through a lifting support. The making method comprises the following steps of: establishing a hyperbolic concave refractive and reflective panorama camera model, determining the distance between the hyperbolic concave reflector and the perspective center of the common perspective camera, determining lens focus of the common perspective camera and charge coupled device (CCD) size, erecting the common perspective camera support, and calibrating the camera. The panorama camera has the characteristics of simple structure, easiness in assembly and the like, and can be used for acquiring pavement image information in the highway survey process; and the acquired images have low distortion in horizontal scenes and vertical scenes.
