SOLID FORM IDENTIFYING AND CONTROLLING SYSTEM

摘要

PURPOSE:To identify forms with high accuracy and high efficiency by retrieving a perception dictionary according to the way an object is seen corresponding to a shift a shift in the viewing point and extracting a common candidate categories for identification. CONSTITUTION:An observing part 20 shifts the photographing viewing point under the control of a collation part 21 and an image polygon is extracted by a picture extracting part 3 and a perception generating part 4. Then a 2-dimensional picture 11 is obtained from an object 10 and the perception information is extracted and transferred to the part 21. The part 21 seaches for an item coincident with said perception information out of a perception dictionary 22 and stores the category candidates. Then the part 21 controls the part 20 to change the viewing point and repeats the procedure by photographing the object again. The obtained category candidates are added to the storage and then to the previous storage and the form category of the object is defined as a trigonal pyramid, for example. This information is delivered. Here a perception transition graph is added to retrieve only the perception to be designated and therefore the retrieving efficiency is improved.
