This measurement system uses delaminated measurement principle, measures the three perpendicular direction
values of the entities. When the measured entity is immerged in the liquid layer by layer, every layer's image are
collected by CCD and digitally processed. It introduces the basic measuring principle and the working process of the
measure method. According to Archimedes law, the related buoyancy and volume that soaked in different layer's depth
are measured by electron balance and the mathematics models are established. Through calculating every layer's weight
and centre of gravity by computer based on the method of Artificial Intelligence, we can reckon 3D coordinate values of
every minute entity cell in different layers and its 3D contour picture is constructed. The experimental results show that
for all the homogeneous entity insoluble in water, it can measure them. The measurement velocity is fast and non-destructive test, it can measure the entity with internal hole.
The major studied in this dissertation is the non-destructive testing method of silkworm cocoon's quality, based on the digital image processing and photoelectricity technology. Through the images collection and the data analysis, procession and calculation of the tested silkworm cocoons with the non-destructive testing technology, internet applications automatically reckon all items of the classification indexes. Finally we can conclude the classification result and the purchase price of the silkworm cocoons. According to the domestic classification standard of the silkworm cocoons, the author investigates various testing methods of silkworm cocoons which are used or have been explored at present, and devices a non-destructive testing scheme of the silkworm cocoons based on the digital image processing and photoelectricity technology. They are dissertated about the project design of the experiment. The precisions of all the implements are demonstrated. I establish Manifold mathematic models, compare them with each other and analyze the precision with technology of databank to get the best mathematic model to figure out the weight of the dried silkworm cocoon shells. The classification methods of all the complementary items are designed well and truly. The testing method has less error and reaches an advanced level of the present domestic non-destructive testing technology of the silkworm cocoons.
