1. A computer-implemented method, comprising: capturing a first image at a first focus setting using a camera of a computing device; capturing a second image at a second focus setting using the camera; identifying, in the first image, a first portion of an object, wherein the first portion has a first sharpness score that exceeds a sharpness threshold, the sharpness threshold indicating an amount of image detail conveyed; identifying, in the second image, a second portion of the object, the second portion having an associated second sharpness score that exceeds the sharpness threshold; determining first depth information for the first image based at least in part on the first focus setting; determining second depth information for the second image based at least in part on the second focus setting; determining a relative depth for the object based on the first depth information and the second depth information; and generating a depth map indicating a location of the object in a field of view of the camera and indicating relative positions for other objects in the field of view of the camera.
