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.

An information processing apparatus includes: an information receiver configured to receive imaging data output from an imaging device; and a processing unit configured to generate a color image based on the received imaging data and control a display device to display the generated color image. The processing unit generates a detection frame constituted as plural regions based on the imaging data, controls the display device to display the generated detection frame as being superimposed on the color image, and displays a temperature for each of the plural regions.

In an image processing apparatus, a first correction unit corrects imaging data acquired from an infrared imaging device, based on a first correction table, and outputs first corrected data. A second correction unit generates a second correction table for the imaging data in a state in which a shutter is closed, and outputs second corrected data based on the second correction table. A saturated region detection unit detects a saturated region in the imaging data. A shutter control unit performs closing control for the shutter, based on a result of detection of the saturated region. An abnormal pixel detection unit detects whether or not the imaging data acquired in the state in which the shutter is closed includes an abnormal pixel. A selection unit selects and outputs either the first corrected data or the second corrected data in accordance with a result of detection by the abnormal pixel detection unit.

Disclosed is a body temperature measuring patch using an IR temperature sensor. The present embodiment provides a body temperature measuring patch using an infrared temperature sensor, which enables the body temperature to be measured more accurately and quickly when a body temperature is continuously monitored by applying a surface mounted device (SMD)-type infrared (IR) temperature sensor and thus implementing a patch-type thermometer.

A method includes capturing and scaling VLC and an IAS outputs to generate a scaled VLC output and a scaled thermal output (STO), aligning the scaled VLC output to the STO to generate an aligned image based on the scaled VLC output and the STO, determining alignment value(s) based on the aligned image, a laser pointer outputting a light beam to produce a laser dot on a target, and capturing a further output of the VLC. The method includes displaying the further output of the VLC (including a representation of the laser dot (RLD)), and an alignment marker, shifting the alignment marker and/or the RLD to a common position; determining coordinate(s) of the output of the IAS based on coordinate(s) of the further output of the VLC where the alignment marker and the RLD are shown at the common position; and storing the coordinate(s) of the output of the IAS.

Various techniques are disclosed to provide for improved detection of elevated human body temperatures. In one example, a method includes receiving a thermal image.

The method also includes determining an expected body temperature using the circadian rhythm model. The method also includes extracting a temperature associated with the person's face from the thermal image. The method also includes comparing the extracted temperature with the expected body temperature to detect an elevated body temperature condition. Additional methods and systems are also provided.
