THERMAL-IMAGE BASED VIDEO COMPRESSION SYSTEMS AND METHODS
A system for capturing a thermal video stream includes a thermal image capture component, such as an IR camera, configured to capture and digitize the thermal video stream having n-bits of data per pixel, a memory configured to store the captured thermal images, and a processor. The processor is configured to select captured thermal images as frames for a video stream and subdivide each captured thermal image into separate m-bit and k-bit image streams. The processor is further configured to compress the m-bit thermal image stream in a video compression format that includes frame and metadata, compress the k-bit image stream using a lossless or substantially lossless compression format, and incorporate the compressed k-bit image stream into the coded m-bit video stream as metadata.
THERMAL GUNSIGHTS
A gunsight for aiming a firearm may comprise a microbolometer and an objective optic positioned forward of the microbolometer for focusing electromagnetic waves on the microbolometer. The objective optic may comprise one or more objective lenses. The gunsight may also comprise a display and an eyepiece optic positioned rearward of the display for allowing a user to view the display through the eyepiece optic. The eyepiece optic may comprise one or more eyepiece lenses. Circuitry of the gunsight is operatively coupled to the microbolometer and the display. The circuitry may comprise one or more processors and a non-transitory computer readable medium storing one or more instruction sets. In some embodiments, the one or more instruction sets include instructions configured to be executed by the one or more processors to cause the gunsight to capture image signals with the microbolometer and display selected images on the display.
Wearable apparatus with integrated infrared imaging module
Various techniques are disclosed for providing a wearable apparatus having an integrated infrared imaging module. In one example, a wearable apparatus implemented as a self-contained breathing apparatus (SCBA) may include a shield to protect a user from an external environment, one or more infrared imaging modules, a projector, a processor, and a communication module for projecting a user-viewable thermal image onto a surface of the shield. Such infrared imaging modules may be positioned internal to the SCBA for protection from a hazardous external environment. In another example, a wearable apparatus implemented as a welding mask may include one or more infrared imaging modules, a projector, a processor, and a communication module, so as to project a user-viewable thermal image onto a surface of a shield of the welding mask, while at the same time protecting these components and the welder's face from a harsh welding environment.
Detecting device
A device for detecting at least one thermographic image including a thermal camera sensitive to infrared radiation for acquiring the thermographic image; a protective case, inside which the thermal camera is inserted, having a window through which the thermal camera is able to acquire the thermographic image; a screen, positioned outside the protective case and movable between a first operating position at which it is superposed on the window to protect it from environmental disturbances and a second operating position wherein it is shifted from the window, allowing the thermal camera to acquire the thermographic image; a pneumatic system for supplying air inside the protective case having an inlet outside the protective case; a computerized command and control unit; the pneumatic system includes means for adjusting and distributing the air operating inside the protective case and in communication with the external inlet controlled by the computerized command and control unit.
Occupant position tracking using imaging sensors
Techniques are disclosed for locating an occupant within an area. The system includes a first sensor including a first plurality of pixels for receiving a thermal energy input from the occupant within a first field of view (FOV) and a second sensor including a second plurality of pixels for receiving the input within a second FOV. A first distance from the occupant to the first sensor is determined based on the input received by at least one pixel of the first plurality of pixels and a first sensor location from an origin. A second distance from the occupant to the second sensor is also determined based on the input received by at least one pixel of the second plurality of pixels and a second sensor location relative to the origin. A coordinate position for the occupant relative to the origin is determined based on the determined first and second distances.
Device Temperature Control Using Device Components
Systems, apparatuses, and methods are described for using one or more components of a device, such as a camera, to generate complementary heat for the device, such as a camera lens of the device. In one aspect this can be accomplished by activating the one or more components and/or by causing the one or more components to operate in a particular manner expected to generate heat. The generated heat may be instead of or in addition to heat generated by one or more dedicated heaters. The selected components may produce heat as an incidental effect for performing other functions of the device.
