Driver’s Cognition of Human Presence in Far-Infrared Images

The authors investigated the display conditions that allow drivers to recognize the presence of humans in infrared images obtained with an automotive night vision system. First, the authors examined how the resolution and gradation of far-infrared images relate to the recognition of human presence. The results showed that the resolution of photocells is a key factor in obtaining high-quality far-infrared images under real-world conditions. It was also found that around six pixels, corresponding to the height of the human face in the camera photocells, represent the threshold level for recognizing the presence of humans. The number of pixels is expressed as ppf (pixels per face height) in this study. Finally, it was observed that the head or the upper part of the human body plays an important role in a driver's recognition of human presence
