Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] In this implementation case, it is assumed that all objects are figure 1 The shown up and down direction placement (the present invention is also applicable to the situation where the direction is reversed at will, but more spatial forms need to be considered) through the conveyor belt, select the type identification and judgment of the side projection form of the object.

[0027] For the process of object type identification in the embodiment, see figure 2 As shown, the specific steps are as follows:

[0028] Step 1: Obtain the morphological features of multiple interrelated projection surfaces for the geometric models of different objects, and select key morphological features. Among them, the interrelated projection surface and key morphological features need to be selected according to the morphological characteristics o...

Abstract

The invention relates to a motion object type recognition method based on multi-projective-plane critical morphological characteristics, which relates to the technical field of the manufacturing automation, and belongs to the object real-time monitoring and information collection. The method comprises the following steps of respectively building critical morphological characteristics of multiple mutually-associated projective planes according to a three-dimensional model of different-type objects; collecting the morphological information of the motion object from the multiple mutually-associated projective planes when the motion object passes through the multiple mutually-associated projective planes; and the automatic recognition of the type of the motion object is conducted according to the critical morphological characteristics of different objects on the multiple mutually-associated projective planes. The method is a universal method capable of effectively solving the difficulty for automatically recognizing multiple motion objects of different types passing through in a mixed operation way.

Description

Technical field: [0001] The invention relates to the technical field of manufacturing automation, and belongs to real-time monitoring and information collection of objects; in particular, it relates to a method for identifying a shape code of a moving object based on key shape characteristics of multiple projection surfaces. technical background: [0002] At present, there are many identification methods for moving objects, the most widely used are barcodes (including one-dimensional barcodes, two-dimensional codes, metal barcodes, etc.) and electronic tags (RFID); in addition, image acquisition and pattern recognition methods are also widely used. . [0003] Bar codes and electronic tags can solve the identification problems of most objects during movement. For example, CN201828928U discloses "an oilfield managed object based on a two-dimensional code technology identification system". The code carrier is used for object identification; and as disclosed in EP1271378-A, a b...
