Image acquisition device for microscopic coding code pattern

The embodiment of the invention discloses an image acquisition device for a microscopic coding code pattern, and relates to the technical field of anti-counterfeiting. The device comprises a lifting module, a driving module and camera equipment, wherein the lifting module comprises a first table top and a second table top, the first table top is used for placing a microscopic coding code pattern to be collected, and the second table top is used for placing camera equipment; the camera equipment is used for collecting a code pattern image of the microscopic coding code pattern and judging whether the current imaging distance is appropriate or not according to the code pattern image, and if not, a lifting instruction is sent to the driving module; the driving module is used for controlling the lifting module to conduct lifting motion according to the lifting instruction so that the second table board can move relative to the first table board. Therefore, high-quality images highly meeting shooting requirements
