具体实施方式 Detailed ways

[0031] 如图1所示,本发明提供一种植入有非红外光识别材料的点阵图形,点阵图形I为肉眼无法分辨、且带有指定形状的标识,其有效面积不小于3*3平方毫米,由至少一组直径为30~40微米的信息点集合按规律排列构成。 [0031] As shown, the present invention provides an implant 1 with a dot pattern identification material non-infrared light, a dot pattern by the naked eye can not distinguish between I and identified with the predetermined shape, the effective area not less than 3 * 3 mm2, a set of at least one set of information dots having a diameter of 30 to 40 microns constituted by the regular arrangement. 信息点集合被划分为方向参考点、中心参考点与检验码。 Information point set is divided into a direction of the reference point, the reference point and the center check code. 信息点集合包括多个由含碳涂料制成、且能够被红外光谱所识别的红外光信息点2,以及多个由非红外光谱所识别的非红外光信息点3,红外光信息点与非红外光信息点相互之间不重叠。 Set comprises a plurality of information dots made of a carbon-containing coating, and can be recognized by the infrared spectrum of the infrared light information dot 2, information dot and the non-infrared light by a plurality of non-identified IR 3, an information dot and the non-infrared light infrared light do not overlap each other between the information dot. 相邻的两个红外光信息点、相邻的两个非红外光信息点或相邻的红外光信息点与非红外光信息点之间的间距为80微米。 The spacing between two adjacent information points infrared light, infrared light non-neighboring two adjacent information dots or infrared light and the non-infrared light information dot information dots 80 microns. 方向参考点、中心参考点与检验码为红外光信息点或非红外光信息点。 Direction of the reference point, the reference point and the center of the check code is an infrared light or infrared light information dot information points.

[0032] 由于点阵图形的面积较小,因此,点阵图形在附着在物品表面后,不会对其外观造成影响。 [0032] Due to the small area of ​​the dot pattern, and therefore, a dot pattern on the surface of the article is attached, it will not affect its appearance. 点阵图形为带有加密标识信息,用于与载体建立对应关系,并识别载体的信息,点阵图形在破坏后无法被读取。 The dot pattern is encrypted with identification information for establishing a corresponding relationship with the carrier, and carrier identification information, the dot pattern can not be read after destruction.

[0033] 由于信息点的直径微小,并且相邻的两个信息点之间预设有相应的间隔距离,在被复印或者扫描的方式复制后,相邻两个信息点之间的距离会发现偏差,指定的形状也会发生变化,从而形成无法被识别的无效编码,因此,信息点的位置、与二者之间的距离可提高点阵图形的防伪性能。 [0033] Since the diameter of minute information dots, and a corresponding preset distance between two adjacent information points, after being copied or replicated in a scanning manner, the distance between the two adjacent points will find information bias, designated shape will change, can not be identified so as to form an invalid code, therefore, the position of the information point, and the distance between the two security performance can be improved dot pattern.

[0034] 在本实施例中,非红外光信息点由磷光粉制成,可采用蓝紫光谱对其进行识别。 [0034] In the present embodiment, the non-information dot is made of an infrared light the phosphor, the blue-violet spectra can be used to identify it.

[0036] 如果采用普通的红外识别装置对本发明的点阵图形进行识别,经识别后,只有获取到由多个红外光信息点构成的点阵图形图像,无法获取到完整的点阵图形图像,使点阵图形具有较高的隐蔽性和安全性。 [0036] If a conventional infrared recognition device recognizes the dot pattern of the present invention, after identification, only the image acquired dot pattern composed of a plurality of information dots of infrared light, can not obtain the complete dot pattern image, dot pattern has high concealment and security.

[0037] 如图2所示,本发明提供一种对植入有非红外光识别材料的点阵图形进行识别的装置,主要包括控制器4、以及与其相连的红外识别模块5、非红光识别模块6、合并模块9、解析模块11、数据库12与反馈模块13。 [0037] 2, the present invention provides a dot pattern implanted with non-infrared light recognition device identification material, mainly comprises a controller 4, and an infrared identification module 5 connected thereto, the non-red recognition module 6, 9 merge module, a parsing module 11, database 12 and feedback module 13.

[0040] 红外识别模块5与非红外识别模块6分别对信息点集合进行识别时,计时模块7会计算红外识别模块与非红光识别模块在识别产品表面信息时的消耗时间值,并将该消耗时间值发送给时间判断模块8。 When [0040] IR identification module 5 and 6 are non-infrared module identification information identifying a set of points, the timing module 7 calculates the elapsed time and the value of the non-red infrared module identification module identification information identifying the product surface, and the elapsed time to a time value determining module 8.

[0041] 时间判断模块8对消耗时间值进行判断,以辨别该消耗时间值是否超出预定的信息识别时间范围。 [0041] Time elapsed time determining module 8 pairs of values ​​is determined, to identify the value of the elapsed time exceeds a predetermined time identifying information. 若结果为是,则反馈模块反馈识别超时,重新开始识别,若结果为否,则执行合并模块。 If the result is YES, the feedback module feedback recognition timeout, recognition is resumed, if the result is NO, then performs a merge module.

[0042] 合并模块9用于将带有红外光信息点的点阵图形图像、与带有非红外光信息点的点阵图形图像进行拼接,以形成完整的点阵图形图像。 [0042] The dot pattern used for merging module 9 with an infrared light image information dots, and the dot pattern is spliced ​​with a non-infrared image information points to form a complete dot pattern image.

[0044] 解析模块11用于对合格的完整点阵图形图像进行解析,以形成数据库能够进行识别的点阵图形编码数据。 [0044] The parsing module 11 for parsing a complete dot pattern image is qualified to form a dot pattern data in the database can be encoded identification.

[0045] 数据库12用于对点阵图形编码数据进行辨别,以判断与该点阵图形编码数据相对应的点阵图形是否有效,并将结果发送至反馈模块13。 [0045] The dot pattern database 12 for discriminating encoded data to determine the dot pattern data corresponding to the encoded dot pattern is valid, and transmits the result to the feedback module 13.

[0046] 反馈模块13用于反馈辨别结果。 [0046] The feedback module 13 for feeding back the discrimination result. 当数据库的判断结果为是,表明识别结果有效,通过反馈模块反馈防伪标识为真;当数据库的判断结果为假时,表明识别结果无效,则通过反馈模块反馈防伪标识为假。 When the determination result is YES database, indicating that a valid recognition result, security identification feedback via the feedback module is true; database when the determination result is false, indicating that the recognition result is not valid, then the security feedback by the feedback module is identified as false.
