Title:
RISK INFORMATION OUTPUT DEVICE
Document Type and Number:
Japanese Patent JP2021144309
Kind Code:
A
Abstract:
To accurately determine risk and output information on the risk.SOLUTION: In an information processor 1, a visual saliency calculation section 3 acquires a visual saliency map obtained by estimating degrees of visual saliency in an image for each entrance road from the image for each entrance road, which is a road for entering an intersection, and a sight line coordinate setting section 4 sets coordinates of ideal sight line in the image for each exit road, which is a road for exiting after entering the intersection, for the visual saliency map. A vector error calculation section 5 calculates a visual attention concentration degree Ps for each exit road in the image on the basis of the visual saliency map and the ideal sight line, and an output section 6 outputs information on risk at the intersection on the basis of the visual attention concentration degree Ps calculated for each exit road.SELECTED DRAWING: Figure 1
