Abstract: The invention relates to an occupant or presence detection system and method where movement detection of an infrared (IR) sensor device and presence detection of an image sensor device are combined. Information derived from an IR movement detection signal is combined with object locations extracted by the image sensor device to distinguish human beings from static objects and improve occupant or presence detection in various applications, such as light control, desk occupancy and people counting in office applications that use advanced sensing bundles (ASB).

Abstract: A process control method for a 3D-printing process using a 3D printer. The 3D printer has a build platform, a light source, a receiving device for printing material and a control device by which an object can be produced layer-wise or continuously from the printing material. The method includes using a thermal imaging camera, the output signal of which is transmitted to the control device, connected to the 3D printer, The method includes the following steps of illuminating a layer or parts of said layer positionally selectively, detecting the temperature of the layer during the polymerisation using the thermal imaging camera, ending the building process of a layer by ending the illumination, the time of the end of the illumination being established by a predefined temperature Tmax or a predefined change in temperature dT/dt being reached.

Abstract: A method and apparatus for measuring a temperature of a substrate located in a semiconductor processing environment is disclosed. The substrate has a top surface and an edge surface, and is positioned in a prescribed location within the semiconductor processing environment. An infrared camera oriented to view one side of the edge surface of the substrate is triggered to obtain an infrared image of the one side of the edge surface of the substrate. The infrared image is processed to obtain a temperature profile of the substrate.

Abstract: A method and a device for measuring a temperature of a wire rod, a storage medium, and a computer device are disclosed. The method includes: determining an effective temperature measurement area according to the infrared thermal image and feature information of the wire rod; projecting preset light onto the wire rod geometric model, tracing a light propagation path of the preset light, and calculating an effective emissivity based on a tracing result of the light propagation path; and correcting temperature measurements in the effective temperature measurement area based on the effective emissivity to obtain a corrected temperature measurement result. The infrared thermal image is acquired, and is analyzed by image processing, thereby dynamically capturing the effective temperature measurement area. The effective emissivity between wire rods is calculated, and then the measured temperature of the wire rod is corrected, thereby improving the accuracy and stability of temperature measurement on wire rods.

Abstract: Methods, systems, and apparatus for an infrared and visible imaging system. In some implementations, Image data from a visible-light camera is obtained. A position of a device is determined based at least in part on the image data from the visible-light camera. An infrared camera is positioned so that the device is in a field of view of the infrared camera, with the field of view of the infrared camera being narrower than the field of view of the visible-light camera. Infrared image data from the infrared camera that includes regions representing the device is obtained. Infrared image data from the infrared camera that represents the device is recorded. Position data is also recorded that indicates the location and pose of the infrared camera when the infrared image data is acquired by the infrared camera.
