Provided is a sensor device including: a sensor unit that emits light and receives light reflected by an object; and a reflection mirror that is a columnar reflection mirror having a reflection surface on a side face and is configured to be rotated on an axis of the reflection mirror as a rotation axis, in which at least a part of the reflection surface forms a logarithmic spiral having the center at the rotation axis in a cross section perpendicular to the rotation axis, and when light emitted from the sensor unit and reflected by the reflection surface moves in parallel in response to rotation of the reflection mirror, the light reflected by the reflection surface is swept.

Sensor device

A spatial recognition device provided with an analysis unit configure to acquire, from an optical device, which is mounted on a moving body and which receives reflected light obtained by radiating light onto a reflective plate provided on a stationary structure positioned within a detection area, reflected light information obtained based on the reflected light in accordance with a radiation direction of the light, and determine a positional relationship between the moving body and the stationary structure on which the reflective plate is provided, based on a distribution of the reflected light information at coordinates within the detection area.

Spatial recognition device, spatial recognition method, and program

A spatial recognition device provided with an analysis unit configured to acquire, from an optical device which receives reflected light obtained by radiating light onto a reflective plate provided on a moving body positioned within a detection area, reflected light information obtained based on the reflected light in accordance with a radiation direction of the light, and analyze a state of the moving body on which the reflective plate is provided, based on a distribution of the reflected light information at coordinates within the detection area.
