Description

Title of the invention: Microimage capture system with zoom function in a self-assembly kit and method Technical field

[0001] The present invention relates to the field of image capture, and in particular, to a system and method for capturing microimages with a zoom function in a self-assembly kit. BACKGROUND OF THE INVENTION

[0002] Three-dimensional microphotography is widely applied to fields such as life science and material science. In these fields, commonly used three-dimensional microphotographic devices mainly include: scanning electron microscope, three-dimensional profilometer, atomic force microscope, and others. A two-dimensional image is obtained using the scanning electron microscope, and relevant researchers regard a gray scale change of an image as a shape change of a surface of a sample, but the two-dimensional gray scale-based information cannot truly reflect the three-dimensional information. The scanning electron microscope further requires complex preprocessing on the sample. The atomic force microscope measures the surface of the sample by moving a probe.The measurement process is one-dimensional, and a contact probe can damage the sample surface. The three-dimensional profilometer uses white light interference to obtain a 3D surface, but the accuracy is not as high as that of the scanning electron microscope and the atomic force microscope. In addition, these professional microphotographic devices are all expensive and have a small depth of field. The depth of field problem severely limits the shape of an object's surface to be photographed. For example, a microstructure of a plant leaf surface is an important factor affecting the free energy of the leaf surface and is closely related to a deposition effect of a chemical solution.However, the surface of plant leaves is usually a multi-scale fractal structure, and a microphotographic device with a shallow depth of field cannot fully observe and photograph such a structure. For such a scale, an ordinary three-dimensional imaging instrument (e.g., laser radar) cannot meet an accuracy requirement.

[0003] The present invention aims to provide a microimage capture system and method with zoom function in a self-assembly kit, in order to improve the accuracy of photographing a three-dimensional shape of an object to be photographed.

[0019] performing a shape from the focusing process on all the focusing images, to determine a micro structure of a surface of the object to be photographed.

[0020] According to one embodiment, before turning a coarse adjustment knob and a fine adjustment knob of a micro-motion platform, to adjust the location of an object to be photographed on the micro-motion platform, the method further comprises the step of:
