摘要： A system for screening persons' temperatures comprises an imaging device configured to generate imagery data, including infrared image data, of a first scene and a second scene. The system receives imagery data from the first scene, identifies persons in the scene using the imagery data, and determines each person's temperature. The system further compares the persons' temperatures to a threshold and indicates a person should be directed to the second scene if the person's temperature is above a threshold. Subsequently, the system determines and compares the person's temperature in the second scene and provides an indication if the person's temperature exceeds a second threshold. Further, a confidence factor can be associated with determinations of persons' temperatures.

摘要： A thermal imaging camera comprises an infrared lens assembly and associated IR sensor for detecting thermal images of a target scene, a processor, and at least one additional sensor. The at least one additional sensor is configured to provide measurement data to the processor, where it is compared to a predetermined requirement. If the measurement data satisfies the predetermined requirement, the camera will prompt the user via a display. During use, the camera can prompt the user to provide annotation data, conduct a thermographic inspection, inspect the target scene, or perform other tasks based on the measurement data.

摘要： Animation of a thermal image captured by a thermal imager that includes automatically changing particular aspects of the presentation of the image. The coloring of the thermal image may automatically change through two or more color presentations. The colors which may automatically change or be “animated” may be any colors in the usual rainbow of color or in the grayscale. The animation may include a series of small, stepwise incremental changes that gradually change the image. If timed correctly and if the increments are sufficiently small, the transitions of the image may appear smooth, in the manner of a movie or cartoon.

摘要： Methods and apparatuses that utilize machine learning techniques to identify maintenance assets using sets of machine-health diagnostic images and link individual machine-health diagnostic images to the identified maintenance assets are described. The sets of machine-health diagnostic images may include a set of thermal images, a set of visible-light images, and/or a set of acoustic images. An identified maintenance asset may comprise an individual machine associated with a unique asset identifier. A diagnostic image linking system may acquire machine-health diagnostic images, apply object detection and other computer vision techniques to identify a particular machine within the machine-health diagnostic images, determine machine properties for the particular machine, generate a feature vector using the machine properties, select machine learning models corresponding with maintenance assets, generate predicted answers using the machine learning models, and generate an asset identifier for the particular machine based on the predicted answers.

摘要： A thermal imaging system includes an infrared camera, a user interface, and a processor. While an actuation of the user interface is detected, the processor is configured to apply non-uniformity correction (NUC) values to infrared image data in infrared images of a target scene; register the corrected infrared images using image stabilization; perform an image-stabilized optical gas imaging process using the registered infrared images to generate optical gas image data indicating a change in the target scene; and generate a display image including the optical gas image data. Actuation of the user interface may be detected while a depressible trigger is depressed, and no longer detected when the depressible trigger is released. Upon detecting the actuation of the user interface, the processor may perform a NUC process to establish the NUC values. A drift indicator in the display image may indicate movement of the infrared camera from a reference position.

摘要： A method and apparatus for optical sensor-based position sensing are provided. In the method and apparatus, a first displacement is detected by a first optical position sensor and a second displacement is detected by a second optical position sensor of an optical position sensor assembly located on a radio frequency (RF) imaging device. A processor coupled to the optical position sensor assembly determines a position of the RF imaging device based at least in part on the detected first and second displacements. The processor determines a tilt of the RF imaging device based at least in part on the detected first and second displacements and associates, in a memory, the position and the tilt of the RF imaging device with data representing an RF image of a portion of a space disposed behind a surface captured by the RF imaging device.

摘要： Systems and methods can be used to detect thermal anomalies in a target scene of an infrared image. Acquired thermal image data can be compared to a statistical thermal profile to detect thermal anomalies in the image data. Anomaly data based on the comparison can be used to generate an image representing locations and/or severity of detected anomalies. Systems can be used to acquire thermal image data for generating and/or updating statistical thermal profiles for use in anomaly detection processes. Auxiliary measurement devices can provide measurement data representative of one or more parameters of the target scene. The measurement data can be used to select from a plurality of possible statistical thermal profiles associated with the target scene to best match the current parameters of the scene.

摘要： Aspects of the invention generally relate to illumination gas imaging and detection. Camera systems can illuminate a target scene with light sources configured to emit absorbing and non-absorbing wavelengths with respect to a target gas. An image of the target scene illuminated with a non-absorbing wavelength can be compared to a non-illuminated image of the target scene in order to determine information about the background of the target scene. If sufficient light of the non-absorbing wavelength is scattered by the scene toward a detector, the target scene comprises an adequate background for performing a gas imaging process. A camera system can alert a user of portions of the target scene suitable or unsuitable for performing a gas imaging process. If necessary, the user can reposition the system until sufficient portions of the target scene are recognized as suitable for performing the gas imaging process.
