WebJan 13, 2024 · Basic Concept. The acceleration of gravity at a point on Earth’s surface results from the combined effects of Earth’s total mass and the subsurface mass differences that occur below. Thus, the gravity method considers how subsurface density variations effect the acceleration of gravity as it is measured along the earth’s surface using a ... WebApr 10, 2024 · 2.1. Traditional Gray-Gravity Method (GGM) Assume I M×N is the image that contains the perturbed laser stripe. It is captured by the camera with the pixels of M rows and N columns. The gray value for the pixel at the ith row and jth column is denoted by I(i,j) and the maximum gray value of the image is I max.Thus, the normalized gray value …
