Document Type and Number:
Japanese Patent JP2004303219
Kind Code:

Abstract:

To provide a vehicle surrounding monitoring device for stably extracting pedestrians by surely determining a binarizing object of a indeterminate form extracted from a picture taken with a camera.

First, an area supposed to correspond to the head of a pedestrian is set to be a reference area (S91 to S94), and two objective areas which are supposed to correspond to spaces over the shoulders of the pedestrian and arranged above the reference area are set in side parts on the right and left of the reference area (S95). Then, an area corresponding to the part extending from the head to the shoulders of the pedestrian caught by an infrared picture is recognized (S96). Next, another objective area supposed to correspond to an area extending from the shoulders to the arms of the pedestrian is set (S97), and an area corresponding to the part extending from the shoulders to the arms of the pedestrian caught in the infrared picture is recognized (S98). When the distance to the whole of the pedestrian is equal to the distance to the area corresponding to the part from the shoulders to the arms, the binarizing object including the areas corresponding to the part extending from the head to the shoulders and corresponding to the part extending from the shoulders to the arms of the pedestrian is recognized to belong to the pedestrian (S99 to S100).
