Japanese Patent JP7002729
Kind Code:
B2
Abstract:
The purpose of the present invention is to recognize from images a dynamic object to be recognized. By means of a spatio-temporal image data generation unit 2, an image recognition device 1 executes a Hilbert scan of frame image data 6 constituting moving-image data 4 to generate one-dimensional spatial image data 7, and further arrays the one-dimensional spatial image data 7 in a time direction to generate two-dimensional spatio-temporal image data 8 that holds spatial information and temporal information. Thus, the image recognition device 1 converts the moving-image data 4 into the two-dimensional spatio-temporal image data 8 while holding the spatial information and temporal information. Next, by means of a CNN unit 3, the image recognition device 1 executes a convolution process in which a two-dimensional filter is used on the spatio-temporal image data 8 to image-recognize a behavior of a pedestrian who is a recognition object. Thus, the image recognition device 1 can execute behavioral recognition of the pedestrian that requires a three-dimensional analysis consisting of two dimensions for space and one dimension for time by means of the image recognition process of the two-dimensional image by the CNN, and thereby can estimate a state of the pedestrian.
