摘要：【中文】本发明提供一种基于机器视觉的瓷砖铺设位置的检测装置和方法，该检测装置包括一个直角灯箱，其内部安装有光源，用于向检测位置均匀打光；三个参数相同的摄像头，分布在灯箱直角处和两条直角边中心，用于检测待铺设瓷砖出现在相应摄像头视野中的相对位置；三对激光测距仪，用于测量其所在位置至待铺设瓷砖的上表面的距离，以及其所在位置至地面的距离；一台工业控制计算机，用于获取每一激光测距仪测量的距离值和每一摄像头采集的图像并对获取的距离值和图像进行处理，得到待铺设瓷砖位置信息。本发明可确保自动化铺设装置铺设瓷砖时瓷砖铺设位置的准确性，满足铺砖工艺需求。 【EN】The invention provides a detection device and a method for tile laying positions based on machine vision, wherein the detection device comprises a right-angle lamp box, a light source is arranged in the right-angle lamp box and used for uniformly polishing the detection position; the three cameras with the same parameters are distributed at the right angle of the lamp box and the centers of the two right-angle sides and are used for detecting the relative positions of the tiles to be paved appearing in the visual fields of the corresponding cameras; the three pairs of laser range finders are used for measuring the distance from the position of the laser range finders to the upper surface of the ceramic tile to be paved and the distance from the position of the laser range finders to the ground; and the industrial control computer is used for acquiring the distance value measured by each laser range finder and the image acquired by each camera and processing the acquired distance value and image to obtain the position information of the ceramic tile to be paved. The invention can ensure the accuracy of the tile laying position when the automatic laying device lays the tiles and meet the requirements of the tile laying process.

摘要：【中文】本发明涉及防伪技术领域，尤其涉及一种变色防伪标签。本发明的目的在于提供一种变色防伪标签，该防伪标签，包括：基材，基材上设定有防伪区；温变油墨层，温变油墨层位于防伪区上；以及随机防伪颗粒，随机防伪颗粒位于温变油墨层上；其中，温变油墨层与基材颜色不同，随机防伪颗粒与基材和温变油墨层叠加之后的颜色不同。该变色防伪标签在受热条件下发生损坏，防止被揭下二次利用，且具有三维立体特征，增强了变色防伪标签的防伪性能。 【EN】The invention relates to the technical field of anti-counterfeiting, in particular to a color-changing anti-counterfeiting label. The invention aims to provide a color-changing anti-counterfeiting label, which comprises: the anti-counterfeiting device comprises a base material, wherein an anti-counterfeiting area is set on the base material; the temperature change ink layer is positioned on the anti-counterfeiting area; the random anti-counterfeiting particles are positioned on the temperature-changing ink layer; the color of the temperature-variable ink layer is different from that of the base material, and the color of the random anti-counterfeiting particles after being overlapped with the base material and the temperature-variable ink layer is different. The color-changing anti-counterfeiting label is damaged under the heating condition, is prevented from being taken off for secondary utilization, has a three-dimensional characteristic, and enhances the anti-counterfeiting performance of the color-changing anti-counterfeiting label.
