摘要： A camera producing visible light images with thermal data. The camera may include visible light lens and sensor, an infrared light lens and sensor, and a display. The display displays some of the visible light image and thermal data from the respective sensors. The visible light image is divided into an array of zones where each zone may provide thermal data associated with the corresponding portion of the target shown in the zone. The camera may sense infrared images also provide audible alarms where the alarm is emitted with a tone of variable output to indicate the relative level of the alarm.

摘要： Systems, cameras, and software for performing optical gas imaging using thermal imaging. Processors are programmed with instructions for a method of detecting gas that includes creating a filtered background image, a filtered foreground image, and optical gas image data, and generating a display image. The filtered background image and filtered foreground images may be created by combining infrared image data from a plurality of images captured by an infrared camera module using filtering processes. The optical gas image data may be created by comparing the filtered background image and the filtered foreground image. An image may be generated that includes the optical gas image data for presentation on a display.

摘要： Systems and methods directed toward combining visible light and infrared images can include processing visible light image data to determine an edge factor value for a plurality of visible light pixels corresponding to the strength of an edge at that location. The edge factor value can be determined using features from the visible light image data and an edge gain input, which may be adjustable by a user. The edge factor values are combined with an edge midscale value to create a first set of modified visible light image data including pixels emphasized based on the strength of the edge in the visible light image. The modified visible light image data is combined with infrared image data to create combined image data having contribution from the infrared image data and the edge factor values from the visible light image data.

摘要： Thermal imaging systems can include an infrared camera module (200), a user interface (208), a processor (222), and a memory. The memory can include instructions to cause the processor (222) to perform a method upon a detected actuation from the user interface (208). The method can include performing a non-uniformity correction (1702) to reduce or eliminate fixed pattern noise from infrared image data from the infrared camera module (200). The method can include capturing infrared images (1704) at a plurality of times and register the captured images via a stabilization process (1706). The registered, non-uniformity corrected images can be used to perform a gas imaging process (1700). A processor (222) can be configured to compare an apparent background temperature in each of a plurality of regions of infrared image data to a target gas temperature. The processor (222) can determine if such regions lack sufficient contrast to reliably observe the target gas.
