  • Publication number: 20240104931
    Abstract: A road surveillance system includes a video acquisition unit, a target determination unit, and a display control unit. The video acquisition unit acquires a video that captures a road. The target determination unit determines, based on a result of comparison between at least one frame image constituting the video and a reference image, and a first criterion, whether the at least one frame image is an analysis target. The display control unit causes a display unit to display information based on a result of the determination. The display control unit includes a first control unit and a second control unit. The first control unit causes the display unit to display an analysis result of at least one frame image being determined to be an analysis target. The second control unit causes the display unit to display detection information indicating that a frame image not being an analysis target is detected.

  • Publication number: 20230230380
    Abstract: An image processing apparatus includes an image processing unit and a risk information generation unit. By processing at least one image, the image processing unit identifies a caution-requiring location being a location where a proximity indicator being an indicator related to a proximity state between a plurality of persons satisfies a criterion. The risk information generation unit outputs information indicating the caution-requiring location. For example, the information is displayed on a display unit through a display control unit. For each person, the image processing unit computes a first distance being the distance to the closest person to the person. Then, for each of a plurality of locations, the image processing unit counts the number of times the first distance has a reference value or less. Then, the proximity indicator is set by using the number of times the first distance has the reference value or less.
