Thermal Temperature Screen

Thermal Technology

A thermal temperature monitoring solution typically encompasses a hybrid thermal camera that combines a Vanadium Oxide (VOx) sensor with a visible-light sensor. Most thermal cameras measure temperature to an accuracy within 1.0° C of actual, adequate for industrial or typical surveillance applications, but monitoring human temperature requires a higher level of accuracy.

A thermal camera uses a thermal imager, essentially a heat sensor, to detect small differences in temperature. These cameras collect the infrared radiation from objects in the scene and create an electronic image based on information about the temperature differences. A special lens focuses the infrared light emitted by all of the objects in view, and in turn, is scanned by a phased array of infrared-detector elements. The detector elements create a detailed temperature pattern called a thermogram in about one-thirtieth of a second. The camera obtains this information from several thousand points in the field of view of the detector array. A circuit board with a dedicated chip then translates the thermogram into electronic impulses and sends the impulses to a signal-processing unit. The signal-processing unit sends the information to the display, where it appears as various colours, each colour based on the intensity of the infrared emission. The combination of all the impulses from all of the elements creates the image

Our Solution

Our Comprehensive solution, offers, that are the highest level of accuracy available.  The system includes a blackbody calibration device that maintains a customizable constant temperature as a reference point for the thermal camera.   In addition, we have network data storage (NDS) to provide storage for video and temperature data as well as face detection technology.

A blackbody is a physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. It not only absorbs radiation but can also emit radiation. The name “blackbody” refers to the function of the device to absorb radiation in all frequencies, not just specific ones. Because of these characteristics, a blackbody device is a desirable calibration source for thermal imaging-based temperature measurement systems. The blackbody functions as a calibration tool and becomes a target object with a precisely known and controlled temperature. This precision is the basis for accurate calibration of infrared pyrometers, increasing the accuracy of thermal imaging equipment. A blackbody at a constant temperature emits electromagnetic radiation called blackbody radiation. This constant temperature is important in external human temperature measurement where accuracy to0.3° C is advised by many international standards organizations.

Our solution also involves Network Data Storage with face detection capability. the face detection capability to add to the accuracy of our system. Accuracy is core requirement of any thermal system is to deliver accurate measurements. In many applications, however, it is not practical to interrupt the flow of people and have them stop at a predetermined spot in order for the system to take a reading. This is a common limitation of handheld thermographic systems, which impede the flow of visitors. One way to increase efficiency is to use face detection as a filter, allowing only temperature measurement of detected faces and nothing else. This capability has several benefits. For one, it can allow for simultaneous readings, as the system only has to focus on faces for measurement. Second, it helps minimize measurement of non-human heat sources, like a cup of coffee. Our system can detect and measure up to thirty faces in the same camera view. Finally, this allows for measurement even when a face is partially covered by a mask or glasses. The images below are snapshots of actual thermal camera video that show human temperature measurements under these circumstances: 1) person wearing glasses and a mask, 2) person wearing a mask, 3) person holding a hot beverage, and 4) person wearing a helmet.
