A system (10) for measuring a distance (12) to an object (14) includes a camera (16) positioned at a location and a signal (30, 32, 34) generated by the camera (16) that is reflective of a camera setting. A controller (18) operably connected to the camera (16) receives the signal (30, 32, 34) and generates an accuracy signal (36) based on the signal (30, 32, 34). The accuracy signal (36) is reflective of a predicted accuracy of a distance (12) measurement. An indicator (38, 42) operably connected to the controller (18) provides an indication reflective of the accuracy signal (36). A method for measuring a distance (12) to an object (14) includes positioning a camera (16) and generating a signal (36) reflective of a predicted accuracy of a distance (12) measurement. The method further includes providing an indication (38, 42) reflective of the signal (36), capturing one or more images of the object (14) at the location, and calculating a distance (12) to the object (14) based on the one or more captured images of the object (14) at the location. |
