Abstract
Provided is an object detection apparatus, which includes a light emission device irradiating an object with light at a wavelength having less disturbance, and a light reception device including a filter that permits light having the aforementioned wavelength to pass, for receiving reflected light from the object. When the disturbance is sunlight, the light having a wavelength whereat the spectral radiative illuminance is damped is employed in accordance with the spectral characteristic of sunlight. In one embodiment, an object detection apparatus, which is mounted in a vehicle, employs, as an object, the eyes of a crew member in the vehicle, and obtains reflected images of the crew member's corneas and retinas to calculate the observed point viewed by the crew member.
