The present invention provides a solid-layered composition having at least two parts. In one embodiment, an RTK base station is disposed at a known location. As long as the maximum height Rmax falls in the range, the adhesive layer never contains air bubbles in such sizes that reflectance is adversely affected. A profile of the upper fillet portion is smaller than that of the lower fillet portion and is not smaller than that of the through hole. The test signal pattern of each channel is compared to a reference signal having the same edge pattern and the delay of each channel is adjusted to maximize cross-correlation between the test signal and the reference signal. The displaying module is configured for displaying the group of captured images associated with the group of profile information matched the group of input profile information.
