  • Publication number: 20250387918
    Abstract: A correspondence identification unit (221) fits a plurality of processing terminals whose positions are to be identified into a template that indicates assumed relative positions of the plurality of processing terminals using grid points, which are intersections of lines drawn in a grid pattern, based on estimated positions respectively corresponding to the plurality of processing terminals, and identify grid points in the template respectively corresponding to the plurality of processing terminals. A template correction unit (222) generates a corrected template by correcting a distance between grid points in the template so as to reduce a degree of deviation calculated based on a distance between each of the plurality of processing terminals and an identified corresponding grid point.

  • Publication number: 20250130303
    Abstract: A position correction device (100) corrects each estimated position when wireless terminals are arranged in a two-dimensional grid pattern, a position of each of the wireless terminals has been estimated as an estimated position, and each estimated position may contain an error, and includes an installation interval estimation unit (110). The installation interval estimation unit (110) performs clustering on the wireless terminals so that a distance between two adjacent clusters satisfies a first installation interval condition in every pair, based on a coordinate component in a lateral axis direction out of coordinate components of each estimated position, and performs clustering on the wireless terminals so that a distance between two adjacent clusters satisfies a second installation interval condition in every pair, based on a coordinate component in a longitudinal axis direction out of the coordinate components of each estimated position.

  • Publication number: 20250131682
    Abstract: An image acquisition unit (21) acquires image data obtained by capturing an image of an indoor unit of an air conditioner. An air outlet detection unit (22) gives, as input, the image data of the indoor unit acquired by the image acquisition unit (21) to an object detection model to detect an air outlet. An area setting unit (23) sets an area of interest to be a range in which a detection target, such as a light emitter installed in the indoor unit or an identification number displayed on the indoor unit, is to be detected, based on a detected area of the air outlet detected by the air outlet detection unit (22).

  • Publication number: 20240185446
    Abstract: A mobile terminal (10-1) detects a terminal-side time (TC) being a duration time of a stationary state of the mobile terminal (10-1) with using a motion sensor. The mobile terminal (10-1) transmits the terminal-side time (TC) and identification information which identifies the mobile terminal (10-1) to a detection device (20-1). The detection device (20-1) detects a person position from an image by image analysis, detects a device-side time (TS) being a duration time of a stationary state of a person existing in the image by image analysis, and compares the device-side time (TS) with the terminal-side time (TC). The detection device (20-1) decides whether or not to associate the person position with the identification information in accordance with a comparison result of the terminal-side time (TC) and the device-side time (TS).

  • Publication number: 20240159418
    Abstract: An object detection unit (212) uses a learned model to detect a plurality of vanes in a captured image in which an air-conditioning indoor unit is captured. A vane selection unit (214) selects a target vane from the plurality of vanes in the captured image. An image display unit (215) displays a superimposed image in which a target identification mark and an adjustment interface are superimposed. A designation acceptance unit (216) accepts adjustment details designated by operating the adjustment interface. An air-conditioning setting unit (217) sets the accepted adjustment details in the air-conditioning indoor unit.
