摘要 |
<p>A situation judging device comprises a local image rate-of-change calculating section for calculating the rate of change with time of the luminance value in a local region of a captured image and a situation judging section for analyzing the histogram of the calculated rate of change with time to local regions and thereby judging the move situation of people and/or the degree of congestion of people. The situation judging device judges the move situation and/or the degree of congestion of people. A congestion estimating device comprises a move information generating section for calculating move information from an image sequence of an image creating section, a texture information generating section for generating image texture information, and a reference move information generating section for holding/updating reference move information used as a reference. The congestion judging device judges various situations of the respective regions according to similarity judgment made on the basis of presence/absence of a move and the texture, estimates the degree of congestion, and provides information on the index of congestion situation and on whether the situation is abnormal or not.</p> |
