Abstract
A ranging sensor includes a light emitting unit includes a plurality of light emitting elements, a light receiving unit including a plurality of light receiving elements, a space control unit, a position estimation unit, and a TOF signal processing unit, operates in cooperation with an RGB camera module, and generates target distance information for generating three-dimensional position information. The space control unit independently controls each element group including a light emitting element and a light receiving element allocated to a common subspace. The position estimation unit estimates, from received light amount distribution of a plurality of light receiving elements receiving a reflected light beam from the target existing in a space of each subspace, a position of the target in the space of the subspace group. The TOF signal processing unit performs TOF signal processing in parallel with channels whose number is less than that of light emitting elements.
