A stereo camera attachable to a windshield of a vehicle, the stereo camera comprising: a base assembly including: a first lens; a first image sensor configured to capture a first image on the basis of incident light introduced through the first lens; a second lens; and a second image sensor configured to capture a second image on the basis of incident light introduced through the second lens; a processor configured to process the first image and the second image; a processor board on which the processor is mounted, wherein the processor board is disposed at a rear end of the first image sensor and a rear end of the second image sensor, wherein the processor board includes at least one memory configured to store images acquired by the first image sensor and the second image sensor; a first housing configured to hold the first lens, the second lens, the first image sensor and the second image sensor; and a second housing disposed at a rear end of the first housing; a windshield bracket including: an attachment part adaptable to windshields having different inclination angles and radii of curvature and attached thereto; and a mount part configured to hold the base assembly so as to enable the first image sensor and the second image sensor to capture forward images from the vehicle, wherein the attachment part is made of a flexible material, wherein the attachment part is flexibly adapted to the inclination angles and radii of curvature of the windshield, wherein the attachment part is attachable to an inner surface of the windshield by means of an adhesive member, wherein the first housing has a greater thickness than that of the second housing and has a thickness that gradually increases toward the first image sensor and second image sensor, wherein the processor board is disposed between a first image sensor board containing the first image sensor and a second image sensor board containing the second image sensor, wherein the processor is positioned at a center of the processor board, and wherein the at least one memory is arranged adjacent to the processor on the processor board and surrounds the processor. a base assembly including: a first lens;
