Embodiment Construction

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. It is to be understood, however, that many of the details set forth in the specification are merely provided to provide the reader with a thorough understanding of one or more aspects of the invention, and that aspects of the invention may be practiced without these specific details.

[0040] like figure 1 As shown, according to the method for identifying and verifying signatures of Nixing pottery pottery of the present invention, the method comprises the following steps:

[0041] Step 1: Scan the ceramic smooth surface with an ultrasonic micro-ranging probe to obtain scanning distance data. The scanned ceramic smooth surface is the same arc or plane as the surface at the signature, that is, the ceramic smooth surface and the surface at...

Abstract

The invention discloses a signature recognition and verification method for Nixing pottery pottery, which belongs to the field of three-dimensional signature recognition, and uses an ultrasonic micro-ranging probe to scan the ceramic smooth surface to obtain scanning distance data. The shape feature is extracted from the three-dimensional signature data to obtain the concave shape feature. The shape feature is extracted from the plane signature data to obtain the morphological feature; the dynamic feature is extracted from the plane signature data to obtain the dynamic feature. Input the concave morphological feature, morphological feature and dynamic feature into the classifier for calculation, and determine the recognition result according to the calculated threshold. The present invention scans and recognizes the three-dimensional model in the ceramic signature by using the ultrasonic micro-ranging probe, and then recognizes the model, and compares the depth and slope of the three-dimensional concave signature, and at the same time combines the plane recognition and comparison together, so that The recognition is more accurate, and the ceramic signature is better recognized, which can realize the anti-counterfeiting of the fake signature of the ceramic signature.

Description

technical field [0001] The invention relates to the field of three-dimensional signature recognition, in particular to a signature recognition and verification method for Nixing pottery pottery. Background technique [0002] The handwritten signature recognition system uses a computer to automatically identify whether a handwritten signature sample is a "true signature" signed by a specific person or a "false signature" imitated by others. In office automation and public safety, the importance of signature recognition is becoming more and more obvious. In most enterprises, especially the administrative departments that often need to issue or sign documents, the way to determine the identity by identifying the authenticity of the signature is easy to be recognized by people. accept. Due to the good application prospects and huge commercial value of signature recognition, many scholars and research institutions around the world have shown great interest. In recent years, dome...
