A product manufacturing method includes acquiring a random pattern in one region on a surface of a first member by capturing an image of the first member; acquiring identification information, based on which a second member is individually identifiable, from the second member, the second member being combined with the first member to constitute a product; storing the acquired random pattern and the acquired identification information in association with each other; and forming the product by combining the first member and the second member.

The present invention relates to a system for control and audit of chemical products application made by vehicles for the agriculture, pestilence, plague, or insects control, or other chemical applications in determined areas to receive these chemical products such the agrochemical application made by manned or unmanned vehicles, being these vehicles aerial, land or watercraft with the aim of treating soil and/or seeds and/or plants characterized by the system comprises a web server running an application; a database application; an internet communication method between the application cloud environment and its end users; desktop computers running web browsers; mobile devices to access the application through the internet; and a GPS device from where GPS files are collected by a device, being the GPS embedded in a vehicle where these files are used as input data for generating the final application reports which contains all detailed information about how much and in which areas (plots) the product was applied.

A method of decoding a coherent RGB color barcode captured by a RGB camera includes: displaying a coherent RGB color barcode on the RGB display; capturing an image of the displayed barcode; performing a pilot block RGB color interference cancellation process to estimate a per pixel color interference; applying the per pixel color interference to the image of the displayed coherent RGB color barcode to extract each separate barcode of the coherent RGB color barcode; binarizing each of the three separate monochrome grey images of each barcode of the coherent RGB color barcode; and decoding each of the three separate binarized monochrome grey images to provide a decoded data for each barcode of the coherent RGB color barcode displayed on the RGB display. A method of decoding an incoherent RGB color barcode captured by a mobile device RGB camera is also described.

An optically readable marker comprises a dash and two dots arranged in a pattern to allow detection of the marker, wherein the dash and dots are collinear, and wherein the dots are of the same size and shape and adjacent to each other. Multiple such optically readable markers may be combined into a composite marker, optionally with one element (i.e. a dash or a dot of the marker) being at least partially shared between two or more markers.

A personalized information reading system for traceability of at least one product and of the product counterfeiting, comprising a QR Code applied to each product. The personalized information reading system includes a plurality of blocks of information containing data related to the at least one product; a plurality of devices on which a dedicated software programme is installed; an encrypting module; a software block, configured for the management of at least one QR Code and of the encrypting module; a database comprising the plurality of blocks of information and a list of the plurality of users registered or enabled to access to one block of information, or part of it, or to more blocks of information.

Technology for generating, reading, and using machine-readable codes is disclosed. There is a method, performed by an image capture device, for reading and using the codes. The method includes obtaining an image, identifying an area in the image having a machine-readable code. The method also includes, within the image area, finding a predefined start marker defining a start point and a predefined stop marker defining a stop point, an axis being defined there between. A plurality of axis points can be defined along the axis. For each axis point, a first distance within the image area to a mark is determined. The distance can be measured from the axis point in a first direction which is orthogonal to the axis. The first distances can be converted to a binary code using Gray code such that each first distance encodes at least one bit of data in the code.

A method of assisting in focusing a three dimensional camera system on an object within a field of view is disclosed. The process involves at the camera system, determining a distance D in a z direction, within the field of view, to a current focal plane; and rendering to a display, an aimer graphic element with the Z direction distance equal to D in a manner that causes the aimer graphic element to move in the Z direction with changes in the focal plane.

A retroreflective element, for example a retroreflector or a retroreflective film, includes a regular arrangement of multiple reflective triples, each having three side surfaces that form an angle between 88? and 92?, preferably between 89? 50 and 90? 10 relative to one another, and particularly preferably stand perpendicularly on one another. At least one selected triple in the arrangement has a security element having at least one diffractive structure on at least one first side surface. A modulation depth of the security element is selected in such a manner that the security element cannot be perceived when the retroreflective element is illuminated at an illumination angle <10?.
