Abstract
A smart device is disclosed which contains a digital camera with an active electronic viewscreen that displays the detected image, in which the camera can sense laser light beams. The smart device has the capability receiving and executing an application program that allows the camera to be used as a grade elevation detector, in which the camera can sense a laser light beam that effectively forms a plane of laser light which defines an “on-grade” elevation for a jobsite. The user can determine this on-grade elevation by running the APP and viewing the display screen to find the (rotating or static) laser beam. An automated APP system can capture the on-grade elevation using a sequence of images that include a grade rod measurement paired with laser beam intensity detection images.
