Optical detection device and optical detection method

An optical detection device, including an optical detection module, wherein the optical detection module comprises:

• a 3D optical detection instrument, disposed along a central axis parallel to a first direction and having a 3D detection lens, wherein a lens direction of the 3D detection lens is oriented toward a predetermined region located apart from the 3D detection lens to detect 3D information of an object positioned in the predetermined region, and the predetermined region is aligned with the central axis;
• an illumination module, arranged around the central axis and between the 3D detection lens and the predetermined region and configured to provide an illumination light to the predetermined region;
• and
• a 2D detection module, comprising a plurality of 2D optical detection instruments arranged around the central axis, wherein each of the plurality of 2D optical detection instruments has a 2D detection lens, a lens direction of each of the 2D detection lenses is arranged offset from the central axis, and each of the 2D detection lenses is configured to capture a 2D image of the object positioned in the predetermined region based on a preset optical path;
• wherein the preset optical path includes at least a first optical path, and the first optical path has a tilt angle relative to the first direction.
