Abstract: A point data acquisition unit acquires point data indicating a reflection point obtained by an optical sensor that receives reflected light of an emitted light beam reflected at the reflection point. An image data acquisition unit acquires image data of an area around the reflection point indicated by the point data. A luminance calculation unit calculates smoothness of luminance of the image data. A fog determination unit determines the density of fog based on a distance, which is determined from the point data, from the optical sensor to the reflection point and the smoothness of the luminance.

Abstract: A point data acquisition unit acquires a set of point data indicating reflection points obtained by an optical sensor that receives reflected light of an emitted light beam reflected at the reflection points. Point data is a pair of first point data indicating a first reflection point, which is a reflection point of a given light beam, and second point data indicating a second reflection point, which is a reflection point at which the intensity of reflected light of the given light beam is lower than that at the first reflection point. A fog determination unit determines the density of fog based on a distribution of a distance between the first reflection point and the second reflection point concerning the point data included in the acquired set.

Abstract: A camera head unit including an image sensor configured to generate an image signal, a main unit configured to perform a signal process to the image signal, and first and second cables are included. Further, a determining section configured to determine whether a connection state is in a first connection state in which the camera head unit and the main unit are connected with each other via a first cable without a second cable or a second connection state in which the camera head unit and the main unit are connected with each other via the first cable and the second cable, and a transmission section configured to transmit the image signal between the camera head unit and the main unit at least via the first cable according to a determination result determined by the determining section are included.

Abstract: A tracking unit (21) takes, as a subject sensor, each of a plurality of sensors, and calculates a detection value at a subject time about a detection item of an object by using a Kalman filter, on the basis of an observation value about the detection item of the object, the observation value being obtained by observing the object with the subject sensor at the subject time. A reliability calculation unit (23) calculates a reliability of the detection value that is calculated on the basis of the subject sensor, by using a Kalman gain in addition to a Mahalanobis distance between the observation value obtained with the subject sensor and a prediction value that is a value of the detection item of the object at the subject time which is predicted at a time before the subject time. A value selection unit (24) selects a high-reliability detection value among the detection values based on the plurality of sensors.

An image data acquisition unit acquires image data of an area around the reflection point indicated by the point data. A luminance calculation unit calculates smoothness of luminance of the image data.

Abstract: A point data acquisition unit acquires a set of point data indicating reflection points obtained by an optical sensor that receives reflected light of an emitted light beam reflected at the reflection points. A fog determination unit projects an overhead view of the reflection points indicated by the point data included in the set acquired by the point data acquisition unit onto a plane in depth and horizontal directions. The fog determination unit makes a decision as to whether in this case the reflection points are distributed in an arcuate shape around the optical sensor. The fog determination unit determines the density of fog based on a result of the decision.

Abstract: A visibility evaluation unit of a light intensity adjustment apparatus calculates, for a detected object ahead of a moving body detected by a non-visible light sensor such as a laser range sensor, a visibility evaluation value resulting from evaluation of visibility, based on image data obtained by a visible light sensor such as a camera. A light intensity adjustment unit of the light intensity adjustment apparatus adjusts the light intensity of headlights for illuminating an area in which the detected object is present in accordance with the calculated visibility evaluation value.
