1. An occupant state detection system comprising:
an occupant monitoring apparatus configured to monitor a physical state of an occupant in a vehicle;
an occupant state detection apparatus configured to detect the physical state of the occupant in the vehicle on a basis of occupant monitoring data from the occupant monitoring apparatus; and
a determination apparatus configured to determine whether the vehicle is in a traveling state or a stopped state, wherein
the occupant state detection apparatus includes
one or more processors, and
one or more memories configured to be communicably coupled to the one or more processors,
the one or more processors are configured to cooperate with one or more programs included in the one or more memories to
receive the occupant monitoring data and determination data from the determination apparatus,
store the received occupant monitoring data and the received determination data in the one or more memories, and
on a basis of the determination data, assign a part of the occupant in the vehicle as a target to be monitored by the occupant monitoring apparatus, to detect the physical state of the occupant,
the occupant monitoring apparatus includes a camera configured to capture an image of the occupant in the vehicle, and
the occupant monitoring apparatus is configured to acquire the occupant monitoring data and transmit the occupant monitoring data to the one or more processors, the occupant monitoring data including expression and behavior of the occupant in the vehicle, and
on a condition that the one or more processors determine, on a basis of the occupant monitoring data, that the occupant is in a sleeping state, with the determination data indicating that the vehicle is in the stopped state, the one or more processors are configured to assign a whole body of the occupant in the vehicle as the target to be monitored, to detect the physical state of the occupant.
