    摘要： A position and pose determination unit (103) is configured to determine a position and an pose of the video acquisition unit (110) in such a way that a level of hiding caused by overlapping of objects becomes low based on environmental object information indicating an environmental object including a structural object present in the monitored area and a placed object placed in the structural object, and staying characteristic information indicating a staying characteristic of the object determined depending on the environmental object. The analysis and display unit (111) is configured to perform at least one of analyzing a video captured by the video acquisition unit (103) at the position and the pose determined by the position and pose determination unit (110) and displaying the video.

    摘要： A trajectory linking apparatus capable of linking a trajectory having a feature value with a trajectory having no feature value is provided. The trajectory linking apparatus includes a feature-including trajectory linking unit and an interpolation unit. The feature-including trajectory linking unit receives trajectory information for each time segment. The trajectory information represents a plurality of trajectories indicating respective movement paths of a plurality of objects detected from image data of a respective time segment, and also indicating whether or not each of the trajectories has a feature for object re-identification. The feature-including trajectory linking unit generates a linked trajectory having a feature by linking a first trajectory having a feature with a second trajectory. The interpolation unit generates an interpolated trajectory by linking a third trajectory to the first and second trajectories.

    摘要： An information processing apparatus (2000) includes a detection unit (2020), a state estimation unit (2040), and a height estimation unit (2080). The detection unit (2020) detects a target person from a video frame. The state estimation unit (2040) estimates a state of the detected target person. The height estimation unit (2080) estimates a height of the person on the basis of a height of the target person in the video frame in a case where the estimated state satisfies a predetermined condition.

    摘要： A surveillance system (1) includes an area information acquisition unit (101), a position information acquisition unit (102), a candidate determination unit (103), and a notification unit (104). The area information acquisition unit (101) acquires information of a surveillance-desired area. The position information acquisition unit (102) acquires pieces of position information of a plurality of portable terminals (20), each portable terminal performing surveillance using an image capturing unit. The candidate determination unit (103) determines a candidate portable terminal (20) to be moved to the surveillance-desired area from among the plurality of portable terminals (20) based on the acquired pieces of position information of the plurality of portable terminals (20). The notification unit (104) outputs a notification to the candidate portable terminal requesting to move to the surveillance-desired area.

    摘要： A parameter calculation unit calculates, for camera layout information of the camera placed in the monitored area and environmental object information representing an environmental object including a structural object present in the monitored area and a placed object placed in the structural object, an image processing performance parameter indicating at least one of a hiding level of an object, an orientation of the object, and a movement of the object based on characteristic information representing characteristics of an appearance and a movement of the object determined depending on an environmental object. A suitability calculation unit calculates camera layout suitability based on image processing characteristic information representing a characteristic of the image processing and the image processing performance parameter, the camera layout suitability being an index of a level of suitability of a camera layout represented by the camera layout information for image processing of the object.
