Abstract: Provided is a time of flight (ToF) sensor and a method for controlling the ToF sensor. The ToF sensor includes a first light emitter configured to output first light of a first pattern, a second light emitter configured to output second light of a second pattern, an image sensor including a plurality of pixels, and at least one processor configured to control the first light emitter and the second light emitter to sequentially output the first light and the second light, obtain, based on the output first light and second light being received through the image sensor by being reflected by a plurality of objects, a first image frame corresponding to the received first light and a second image frame corresponding to the received second light, and identify distances between the ToF sensor and the plurality of objects based on the first image frame and the second image frame.

Abstract: A wide-angle, high-resolution distance measurement device according to one aspect of the present disclosure comprises: a light source which emits structured light; a camera which forms an image by capturing reflected light, which is the structured light emitted from the light source and incident on the camera after being reflected by an obstacle; and a resolution correction lens which is disposed in front of the camera and corrects the reflected light which is reflected by the obstacle and incident on the camera, such that the resolution of the image formed by the camera is uniform irrespective of distance.
