In-hole illumination stereopair imaging device

The invention discloses an in-hole illumination stereopair imaging device which comprises an outer shell, wherein a transparent tubular outer shell body is arranged at the lower portion of the outer shell, a camera shooting device is arranged on the inner wall of the top of the outer shell, a light source is arranged on the inner wall of the middle of the outer shell, double frustum surface lenses are arranged at the bottom of the outer shell and comprise an upper frustum surface lens and a lower frustum surface lens arranged below the upper frustum surface lens, the cone apex angle of the upper frustum surface lens is smaller than that of the lower frustum surface lens, a penetrating hole penetrates through the upper frustum surface lens and the lower frustum surface lens, and a compass is arranged below the penetrating hole. The device achieves the in-hole full-view and stereoscopic optical detection through the built-in light source, the technology of the combined type double frustum surface lenses and the single camera shooting device, the full-view and stereoscopic imaging detection on a drill hole wall with 360 degrees is achieved, and the recognition capability and detection accuracy to targets are improved. The in-hole illumination stereopair imaging device is ingenious in design, compact in conception, simple in structural system and easy to achieve.
