Student Post: FreeCAD FEM Module Results

Dear Reader, In accordance with my timeline, I have explored the capabilities of FreeCAD’s FEM Module along with other auxiliary modules in order to find a reliable software program that enables easy application and analysis of stress on a 3D object. I explored the basic functionality on a trivial yet essential structure as shown in Continue reading Student Post: FreeCAD FEM Module Results

Student Post: Success with ROS and OpenNI, Python Scripting with OpenCV

Greetings, This week I have finally found success with our implementation of ROS and OpenNI on our Linux Mint machine in the Forensics Lab. I ended up resolving our global frame issue and have received images from the Asus Xtion Pro Live in addition to point clouds! When running roslaunch rviz rviz with OpenNI launch Continue reading Student Post: Success with ROS and OpenNI, Python Scripting with OpenCV

Student Post: Project Timeline for Structural Refinement to Counter Application of Forces

Dear Reader, The sphere packing software currently generates 3D internal structural meshes for hollow 3D objects. However, our current usage of sphere packing does not provide a major improvement over simple manual generation of uniform truss structures. The true advantage to using sphere packing is actually the ability to selectively manipulate local regions of the Continue reading Student Post: Project Timeline for Structural Refinement to Counter Application of Forces

Student Post: ROS and OpenNI Update

Greetings, This past week I have worked on installation ROS (Robot Operating System) on our desktop in the Ars Geometrica Lab in ISAT. With the ROS installation complete and usable, I began focusing on getting the OpenNI_launch and OpenNI_camera nodes working together to produce visuals from the Asus Xtion Pro Live. This was indeed more Continue reading Student Post: ROS and OpenNI Update

Student Post: ROS and Asus Xtion Pro Live

Greetings, This week I will exploring using the Asus Xtion Pro Live within the ROS environment. We have acquired a desktop machine for the Ars Geometrica Lab in ISAT that we have install Linux Mint on to use with ROS. A little bit about ROS. Robot Operating System (ROS) is a collection of software frameworks Continue reading Student Post: ROS and Asus Xtion Pro Live

Student Post: Xtion Pro Live Stereo Camera and OpenNI

Greetings, This week I have been setting up the ASUS Xtion Pro Live Stereo RGB camera to be used along with an open source SDK known as OpenNI for quick prototyping and 3D motion/depth sensing. This camera could be beneficial for us in prototyping and proof of concept going forward. The RGB sensor on the Continue reading Student Post: Xtion Pro Live Stereo Camera and OpenNI

Student Post: BoofCV, Image Segmentation, and 3D Scanner

Greetings, This past week Dr. Bowers and I met in order to come up with some ideas as to how to move forward with our problem of comparing meshes and/or images for error detection. Essentially, we were able to address some problems we’ve been having with some new ideas: Image segmentation Real Time/Video Structure for Continue reading Student Post: BoofCV, Image Segmentation, and 3D Scanner

Student Post: OpenSfM Revisited, Epipolar Geometry, and Possibility of Rendering

Greetings, I’ve continued to delve into the OpenSfM configuration files to attempt to get denser meshes without much promise. The meshes seem to be similar; however, with the yellow spiral I did receive a less distorted image that could be on the road to where we want to be. The figure is shown below: So Continue reading Student Post: OpenSfM Revisited, Epipolar Geometry, and Possibility of Rendering
