![]() To avoid trouble defining clearance shapes, and to take advantage of part symmetry when defining picks, verify the origin of the part model is within the volume of the part, and with its axes aligned to the rotational symmetry of the part. A simple set of instructions can be found at Reset origin ScalingĪctiNav requires the mesh to be scaled in millimeters. There are many tutorials, videos, and user groups available for using MeshLab. MeshLab is an open source system for processing and editing 3D triangular meshes. Some models also have unavoidable flaws due to reflections or gaps. If the model was created incorrectly, it may also be necessary to change the scale. stl and use 100% as scale.įor best performance and easiest editing in ActiNav, the part mesh should have its origin in a reasonable place, and have an appropriate number of faces in the mesh. Once a mesh is produced, save the file as.Bear in mind that you only need to model the surfaces that the 3D sensor can see, and only good enough to locate the part in space. Use default settings -or- feel free to fine tune for filling hole lengths, polygons.Click “Mesh” tool and select “Unwatertight” model to generate a 3D mesh Once you’re satisfied with the final merged scan, convert this to a mesh.If automatic mode does not yield a good match then feel free to use “Align” tool on the right toolbar to manually align scans by selecting three different points on each scan The software will align scans iteratively.Change the position of the part on the turntable so the missing pieces are visible to the scanner, and repeat the above steps for each orientation. To capture the full 360 degree of part (such as the bottom that is on the turntable), you will need to scan multiple orientations. Remember that for bin picking you must have a model that shows all sides of a part.Once a scan is completed, delete any unnecessary points with the “edit/remove” tool.Increase the number of steps only if you want to capture very accurate surface details (Rarely necessary for ActiNav). Choose appropriate brightness/shade for scanning.For ActiNav, use the following settings in Einscan software:.Alternatively, here is a more general youtube video:.Refer to this video on how to create a mesh specifically for ActiNav:.Follow the user manual procedure for hardware installation, license activation, and to create/clean a mesh.Download spec sheet and user manual from Einscan:.Use white matte spray to coat shiny parts. For reflective parts, the part needs to be made non-reflective. It can create 3D meshes for parts that don’t have a CAD file or a commercially created scan. If you work with 3D scanning and find that you need a good tool for cleaning up your scans, MeshLab is a great program.The Einscan SE is a moderately priced desktop scanner from Shining3D. If you are looking for a 3D modeling program to create models from scratch, this is not the program for you. MeshLab is an advanced tool that is recommended for experienced users in the 3D development industry that are involved with 3D scanning. This program also provides tools for interactive painting of mesh colors and selections as well as smoothing. Remeshing filters can take high quality edges and collapse them into simplified shapes while preserving the texture coordinates. It has filters that allow you to remove null faces and other small unused components as well as automatically fill holes. MeshLab is free to use under the GNU General Public License as long as proper citation is made.ĭesigned to help with the processing of unstructured models created during 3D scanning, MeshLab provides many tools to clean up these meshes and convert them into usable 3D models. It is used for processing and editing unstructured 3D triangular meshes in 3D projects. MeshLab is an open source 3D mesh processing application used by experts in 3D development. Interactive mesh color and selection painting.Customizable OpenGL Shader based rendering.Multiple filters for mesh cleaning, colorization, and remeshing.
