The utility model provides an optical detection device, which comprises a camera, a semi-transparent and semi-reflecting mirror, a coaxial light source, a bowl light source and a low-angle ring light source, and is characterized in that the semi-transparent and semi-reflecting mirror is used for reflecting horizontal light rays emitted by the coaxial light source into vertical downward coaxial light rays and projecting the vertical downward coaxial light rays to a target object below; the bowl light source is located below the semi-transparent and semi-reflective mirror, and the bowl light source is used for irradiating a target object from different directions; the low-angle annular light source is arranged below the bowl light source and irradiates a target object from the periphery; the reflected light reflected by the target object reaches the semi-transparent and semi-reflective mirror along the central axis of the bowl light source and is transmitted into the camera through the semi-transparent and semi
