sensors - What is the cheapest / easiest way of detecting ...

Ideally, I'd like to use an inexpensive sensor or combination of sensors to detect a person within a room and localize that person. I would like the robot to enter a room, detect if a human(s) is/are present and then move to the detected human. The accuracy does not need to be 100%, as cost is more of a factor. I'd like the computational requirements of such a sensor to be such that it can run ...

A sensor to detect human body conditions in real-time

· The patch-based sensor developed here was made of a biometric-friendly waterproof material, thus improving the difficulties in acquiring accurate information due to the skin-attachment problem. In addition, the sensor can also be connected to a smartphone using Bluetooth, so biometric data can be saved to a cloud server 24/7. This will enable a timely response to various emergencies …

Remote Sensing and Human Health: New Sensors and New ...

· The detection of urban features requires higher spatial resolution systems than needed for detecting the presence of human settlements. Some disease vectors are associated with specific urban features such as housing type, which can only be detected by sensors with very high spatial resolution. In the future, new sensors may be able to provide information on the urban environment

Sensors | Special Issue : Human Detection, Identification ...

· A thermal camera image can reveal a human body based on body temperature, which is detectable in the range of medium-wavelength infrared (MWIR) at 3–8 µm and long-wavelength infrared (LWIR) at 8–15 µm. Nevertheless, human detection, identification, and recognition of gestures and behaviors, based on thermal cameras, are challenging issues.

Detection and tracking of a human using the infrared ...

· The Passive Infrared (PIR) sensor is used to detect the presence of human. But this detects the human only if they are in motion. Grid-EYE sensor overcomes the limitation of PIR sensor by detecting the human at stationary position. The Grid-EYE sensor detects the human using the infrared radiation radiated by the human body.

· Nevertheless, human detection, identification, and recognition of gestures and behaviors, based on thermal cameras, are challenging issues. This is because thermal cameras often produce an image of low signal-to-noise ratio (SNR) and a halo effect near the human. In addition, the distinction between the human and the background in the thermal image can be reduced when the background ...
