摘要： A three-dimensional reconstruction system includes an infrared light source array including a plurality of infrared sub-light sources, and each of the infrared sub-light sources emitting an infrared light, and different infrared sub-light sources being coherent light sources, an infrared detector configured to receive an infrared light reflected from a target object, the reflected infrared light being a reflected light of an interference beam emitted by the coherent light source, a calculation circuit, configured to calculate a reference distance between a reflection point on the target object and the infrared sub-light source according to the reflected infrared light and the infrared light emitted by the infrared sub-light source, and a three-dimensional reconstruction circuit, configured to perform reconstruction of a three-dimensional image on the target object according to the plurality of reference distances.
