How to build a 3D model using a plane and a line?

Question

Programming

Please help with advice - how can I do image processing to build a 3D model on it.
I understand the process like this: let's say there is a model that is illuminated by a bright green (thin) line. The image is captured directly from the camera, then each pixel in the image is viewed from left to right and a green pixel is searched from top to bottom, then the coordinates of all green pixels are stored as points in 2D (2-dimensional array) space from the current image, then the next image is captured, on which the position of the green dots is slightly changed, and then...
...and then I just can't imagine how to implement the connection of the previous points with the current ones to convert them into the first part of the 3D PL model
: Java or Delphi

Answer 1

The points that are either on adjacent rows of the matrix on the same frame, or on the same row on adjacent frames are connected. The result is a grid of quadrilaterals. They can be divided into triangles along a shorter diagonal.
If there is no green dot on any line, there will be a hole in the model.

Answer 2

well, the number of points you have is constant, so... just finish building the edges.
