Meshlab measuring tool7/24/2023 ![]() ![]() The “MeshroomCashe” folderĬontains the subfolder “Meshing,” where the 3D scan is saved as an OBJ 3D model. The project files are then stored in this folder. When we click the “Start” button in Meshroom, we are asked where the cache folder shouldīe created. Many users have the problem that they cannot find the 3D model (OBJ format) created by Way.) Swann Rack / Holocreators After we click the “Start” button, Meshroom asks where to save the MeshroomCashe folder (OBJ is a very similar format to STL and can be processed in the same After the software has calculated the 3D model, the data isĮxported as an OBJ file. Press startĪnd the software does the rest. Next, import all the photos into the Meshroom software- simply by drag-n-drop. Upright and one inverted to capture the interior features Step 3: Creating the 3D Model (photogrammetry) in Meshroom Swann Rack / Holocreators We import the photos to Meshroom Object we want to 3D scan should have distinctive geometric features and should not be Shadows have a negative effect on the photogrammetry process. Photogrammetry works best with diffuse lighting. With a cell phone-the more images, the better. ![]() We place the part on a box and take lots of pictures from different angles and perspectives Step 2: Taking Pictures of the Part Swann Rack / Holocreators We take (at least 100) pictures of the part with a mobile phone camera from different angles The reason is that the 3D model is calculated from photos, and the computer does not know Therefore, we need a reference measurement. Photogrammetry (that’s the name of this 3D scanning technique) has the disadvantage that We determine an average diameter of 76.2mm. This way, measurement outliers areĮliminated. Times with the caliper and determine the average value. Step 1: Manual Measurement Swann Rack / Holocreators Measuring a metal part with a caliperįirst, we measure our part (“fuel sensor”) manually.
