Outdoor Human Comfort Exploration: A Multi-Physical Approach with Sound, Light, and Heat Panoramic Measurement

Panoramic photography is a technique that allows images to be stitched together to extend the field of view of a scene, regardless of the camera's optics. In this paper, this technique is adapted to acoustic cameras to explore the extended acoustic field. This appears as an interesting alternative to measure an impulse response in a complex architectural scene, or to study a large urban scene. The temporal and frequential spatialization of sound reflections allows us to identify phenomena such as multiple reflections. These results can be compared to raytracing simulations. This same panoramic representation, extended to other physical fields such as light and heat, allows us to have a global and multi-physical vision of the comfort of a person. This method opens the way to immersive experiences in which the whole perceptible environment is taken into account.
