Digital outcrop model reconstructing method

A Digital Outcrop Model (DOM) reconstructing method, characterized in that it comprises:

• placing (1) at least one image acquisition device for each image of a plurality of images to be captured;
• capturing (2) the plurality of images;
• processing (4) pairs of captured images;
• aligning (3) the plurality of images by identifying a plurality of homologous points between them;
• generating (4) at least one alignment sparse cloud;
• performing densification (5) of the at least one alignment sparse cloud to transform the at least one sparse cloud into at least one dense cloud;
• performing a first segmentation (6) of at least one dense cloud into at least two dense cloud portions, based on at least two categories of geological relevance levels, wherein the at least two categories of geological relevance levels comprise a high geological relevance category and a low geological relevance category;
• carrying out a first decimation (7) of at least one dense cloud portion in the low geological relevance category;
• joining (8) the at least two dense cloud portions and obtaining at least one new dense cloud, wherein the at least two dense cloud portions comprise at least one dense cloud portion of the high geological relevance category and at least one dense cloud portion of the low geological relevance category, wherein at least one dense cloud portion of the low geological relevance category has undergone the step of carrying out a first decimation (7);
• generating (9) at least one three-dimensional triangular mesh from at least one new dense cloud;
• performing a second segmentation (10) of the three-dimensional triangular mesh into at least two three-dimensional triangular mesh portions, based on at least two categories of geological relevance levels, wherein the at least two categories of geological relevance levels comprise a high geological relevance category and a low geological relevance category;
• carrying out a second decimation (11) of at least one portion of a three-dimensional triangular mesh in the low geological relevance category;
• performing a third decimation (12) of at least one portion of a three-dimensional triangular mesh in the high geological relevance category;
• carrying out a first texturing (13) of at least one portion of a three-dimensional triangular mesh in the high geological relevance category, which has undergone the step of carrying out a third decimation (12);
• carrying out a second texturing (14) of at least one portion of a three-dimensional triangular mesh in the low geological relevance category, which has undergone the step of carrying out a second decimation (11);
• and
• joining (15) the at least two three-dimensional triangular mesh portions, wherein the at least two three-dimensional triangular mesh portions comprise the at least one three-dimensional triangular mesh portion of the high geological relevance category and the at least one three-dimensional triangular mesh portion of the low geological relevance category, which have been textured, and forming at least one object comprising at least one Digital Outcrop Model (DOM).
