Claim 0:
1. A detection device for detecting a target behavior that is a vehicle behavior subjected to detection in a preset detection area using a laser radar that generates point cloud information by irradiating the detection area with laser light and receiving reflected light resulting from the irradiation with the laser light, the detection device comprising:
an acquisition unit configured to acquire the point cloud information;
a vehicle detection unit configured to detect a vehicle based on the point cloud information; and
a behavior detection unit configured to detect the target behavior in response to the vehicle detected by the vehicle detection unit having moved from a first area to a second area, wherein
the first area and the second area are included in the detection area and are set according to the target behavior,
the vehicle detection unit calculates coordinates of both ends in a width direction of the vehicle as position information indicating a position of the vehicle based on the point cloud information, and
the behavior detection unit determines an area in which the vehicle exists using the position information.
