1. A cabin-inside detection device, comprising:
processing circuitry configured to
acquire first data acquired by a first sensor;
acquire second data acquired by a second sensor installed above a seat in a cabin;
estimate a position of a front-seat occupant on a basis of the acquired first data;
determine a detection range of the second sensor on a basis of the estimated position of the front-seat occupant; and
detect a rear-seat occupant on a basis of the acquired second data and the determined detection range of the second sensor.
