An electronic device with an image sensor may capture an image of the surface of a structure as a user moves the device across the surface of the structure. The electronic device may have sensors such as a magnetometer, an acoustic sensor, and a thermal sensor for gathering sensor data. An accelerometer and a gyroscope within the electronic device may be used in gathering position information. The image may be captured by gathering image tiles and stitching together the image tiles to form the image. An object such as a ferromagnetic object may be embedded within the structure below the surface. The electronic device may have a display on which the image is displayed. Information about the location of the object which is gathered using the sensors may be overlaid on top of the displayed image. |
