  • Patent number: 12287310
    Abstract: A method of classifying a package based on stiffness of the package, wherein the package includes carton and is filled with food product, the method including applying a force on the package, retrieving a sample value by measuring a deformation of the package caused by the force, determining a difference between the sample value and a reference value, and classifying the package as belonging to a first category if the difference is within a threshold interval, otherwise classifying the package as belonging to a second category.

  • Patent number: 12083689
    Abstract: In picking up tools in an automatic milking arrangement, the positions of the tools are determined by registering, via a camera at an origin location, three-dimensional image data representing the tools whose positions are to be determined. Using an algorithm involving matching the image data against reference data, tool candidates are identified in the three-dimensional image data. A respective position is calculated for the tools based on the origin location and data expressing respective distances from the origin location to each of the identified tool candidates. It is presumed that the tools have predefined locations relative to one another. Therefore, any second tool candidate is disregarded, which is detected at a separation distance from a first tool candidate when the separation distance exceeds a first threshold distance in relation to the predefined relative locations.

  • Patent number: 11991982
    Abstract: Tools in an automatic milking arrangement are picked up by using a robotic arm (110). The robotic arm (110) moves a camera (130) to an origin location (PC) from which the camera (130) registers three-dimensional image data (Dimg3D) of at least one tool (141, 142, 143, 144). The three-dimensional image data is processed using an image-based object identification algorithm to identify objects in the form of the tools and hoses (152). In response to identifying at least one tool, a respective tool position (PT1, PT3, PT4) is determined for each identified tool based on the origin location (PC) and the three-dimensional image data. Then, a grip device (115) is exclusively controlled to the one or more of the respective tool positions (PT1, PT3, PT4) to perform a pick-up operation. Thus, futile attempts to pick-up non-existing or blocked tools can be avoided.

  • Publication number: 20240150057
    Abstract: A method is provided for heat treating a food product contained in a package. The package is made of a packaging material comprising a carton layer. The method comprises exposing the package to hot water to thereby transfer heat from the hot water to the food product, drying the package, such that a water content in the carton layer of the packaging material is reduced, and exposing the package to cold water to thereby transfer heat from the food product to the cold water.

Therefore, any tool candidate is disregarded, which is detected at such a position that the position for the candidate deviates from the spatially even distribution.

  • Publication number: 20230252615
    Abstract: An imaging system registers image data (Dimg) in connection with an installation performing at least one action relating to an animal. A system for image data quality assurance contains a control unit and a digital storage unit. The control unit obtains image data (Dimg) registered by the imaging system when the installation is in an idle mode. The control unit analyzes the obtained image data (Dimg) to determine if a cleaning action to remove dirt (D) from a front window of the imaging system has been performed. If it is determined that such a cleaning action has been performed, control unit (120) causes a point in time for the cleaning action to be recorded in the digital storage unit (130) for use performance tracking of the installation in conjunction with the cleaning actions.

  • Publication number: 20230210081
    Abstract: An offset for a first milking tool in a tool carrier of an automatic milking machine is determined as a spatial vector between a tool reference position (TRP) and an estimated actual position (TAP) of the milking tool. A three-dimensional image data is registered that represents a teat (T) during attachment to and/or detachment from the milking tool. The image data is processed by searching, within a search zone, for a predefined part (MP) of the teat (T) while the teat (T) is attached to the milking tool. Provided that the predefined part (MP) fulfills a measurement criterion, a distance (doff) is calculated between a specific point of the predefined part (MP) and the tool reference position (TRP). The offset is then determined based on the calculated distance (doff).
