This should give you the basics to generate a heat map of height for a 3D model (in this case a fossil dinosaur footprint), using CloudCompare (One of my top choices of freely available software*). I’m going to assume you … Continue reading How to generate a height map with CloudCompare
If you’ve been following my vague attempts to try different pieces of photogrammetry software, I imagine you will be very interested indeed to read the following paper: Knapitsch et al 2017 (link to paper at the bottom of that page). The authors generate some lovely ground truth data with laser scanners, then record images with video cameras. Then they throw everything at the data sets and rank the software pipelines based on accuracy. SPOILERS: Looks like COLMAP (which I cover here) performs best out of the freely available options, by a fair margin. As an aside, I’ve been running COLMAP … Continue reading Photogrammetry Testing: Doing it properly (by someone else)

For the last couple of days and nights, I’ve been doing my best to try and get my Maya scripts working to convert XROMM animations into input files for LIGGGHTS. I’ve previously done this for my paper with Stephen Gatesy, … Continue reading I really dislike rotation maths!
Small post announcing the publication of a new paper: Xing, L., M. G. Lockley, H. Klein, P. L. Falkingham, J. Y. U. L. Kim, R. T. Mccrea, J. Zhang, W. S. P. Iv, T. A. O. Wang and Z. Wang … Continue reading New Dinosaur footprints from China + open data
Science Videos.org did a short 10 minute interview with me about our recent lungfish paper and more generally about locomotion in the fossil record. The page is here: http://sciencevideos.org/locomotion-in-the-fossil-record/ Or you can watch the video here: Continue reading Interview with ScienceVideos.org
Part 1: Photoscan | Part 2: VisualSFM+MeshRecon | Part 3: VisualSFM+PMVS+Meshlab | Part 4: OpenMVG + MVS | Part 5: MVE | Part 6: ReMake | Part 7: SMVS (+MVE) | Part 8: COLMAP I have previously outlined my goal of testing multiple photogrammetry solutions on a single dataset, and reporting times and results. I’m using a dataset based on photographs of this Styracosaurus model (I’ve had it since I was quite young): The dataset has 53 photos in total, and is available from this link. [This will be moved to figshare in due course]. The model is about 12 … Continue reading Photogrammetry testing 7: SMVS (+MVE)
