The paper considers an algorithm for searching for the time of residential roof inspection using an unmanned aerial system, which incorporates unmanned aerial vehicles (UAV) of a multicopter type with a thermal imaging device as a transporting load. Algorithms and their implementation for the problem are considered. The problem of multicopter group movement with restrictions on load, range, roof height and other characteristics is solved. An original algorithm for the system functioning is proposed and justified. The advantage of the algorithm is a quick solution search, visibility and the ability to be verified by the user. There are some disadvantages, such as the resulting solution being suboptimal, the memory complexity growing exponentially, and the UAV charging time being out of consideration (in the absence of a replacement battery). The algorithm is implemented in the MatLab environment, and the example of calculations is presented, the computational experiment is conducted. In further research, it is planned to introduce a larger number of restrictions and conditions and also to test the dynamic change in logistics routes for UAV failures.

ABSTRACTRapid and sensitive screening tools for SARS-CoV-2 infection are essential to limit the spread of COVID-19 and to properly allocate national resources. Here, we developed a new point-of-care, non-contact thermal imaging tool to detect COVID-19, based on image-processing algorithms and machine learning analysis. We captured thermal images of the back of individuals with and without COVID-19 using a portable thermal camera that connects directly to smartphones. Our novel image processing algorithms automatically extracted multiple texture and shape features of the thermal images and achieved an area under the curve (AUC) of 0.85 in detecting COVID-19 with up to 92% sensitivity. Thermal imaging scores were inversely correlated with clinical variables associated with COVID-19 disease progression. We show, for the first time, that a hand-held thermal imaging device can be used to detect COVID-19. Non-invasive thermal imaging could be used to screen for COVID-19 in out-of-hospital settings, especially in low-income regions with limited imaging resources.

It is by the emissivity of the goal objects and the noise problem of the high temperature images that people are puzzled during the course of the cutting temperature tested by the application of thermal imaging device. By using thermocouples, and getting the comparison of thermocouples and the thermal imaging system temperature, we calibrate object emissivity, handle the image noise by improved median method, carry on the edge extraction of image, obtain the temperature of measured objects, and finally confirm the accuracy of the data got by the thermal imaging device with contact measurement.

Abstract Ability to detect heat energy loss from electrical equipment can be proven crucial to avoid overheating and unexpected fire incident. The thermal remote camera was invented to prevent power outages or electrical machinery failures. Thermal imaging cameras are device which converts thermal energy (heat) into infrared spectrum to inspect a specific object or scene. Imagery that reflects the spatial variability of temperature differences in a scene observed by a thermal camera are called thermal images. Due to the complexity of the device, it can be cost and not a solution sought for. This research presents the designing and fabrication of low-cost thermal imaging cameras that plays major role in detecting heat energy losses in various applications. This prototype of thermal imaging cameras is tested to monitor and diagnose the heat health, especially in electrical installations and components in non-contact mode. Based on the test result presented, the prototype able to detect heat energy spectrum up to 80°C. The 8x8 thermal array able to calculate average temperature of the tested items.
