Point-cloud generated form one minute video captured on iPhone6. Used ‘Free Video to JPG Converter’ (https://www.dvdvideosoft.com) to get 200 images. Point-could has generated from Agisoft Metashape, then used MeshLab to reduce the density (one-third of its original size).
To 3D or Not 3D: Choosing a Photogrammetry Workflow for Cultural Heritage Groups
The 3D reconstruction of real-world heritage objects using either a laser scanner or 3D modelling software is typically expensive and requires a high level of expertise. Image-based 3D modelling software, on the other hand, offers a cheaper alternative, which can handle this task with relative ease. There also exists free and open source (FOSS) software, with the potential to deliver quality data for heritage documentation purposes. However, contemporary academic discourse seldom presents survey-based feature lists or a critical inspection of potential production pipelines, nor typically provides direction and guidance for non-experts who are interested in learning, developing and sharing 3D content on a restricted budget. To address the above issues, a set of FOSS were studied based on their offered features, workflow, 3D processing time and accuracy. Two datasets have been used to compare and evaluate the FOSS applications based on the point clouds they produced. The average deviation to ground truth data produced by a commercial software application (#Metashape, formerly called #PhotoScan) was used and measured with #CloudCompare software. 3D reconstructions generated from FOSS produce promising results, with significant accuracy, and are easy to use. We believe this investigation will help non-expert users to understand the photogrammetry and select the most suitable software for producing image-based 3D models at low cost for visualisation and presentation purposes.

We may be well aware of ‘Heritage Interpretation’ and the role of ‘Interpreter’. However, is there something called ‘Digital Heritage Interpretation’? When we use a mobile app and visit/explore a heritage site, can we refer that ‘app’ as an ‘interpreter’? If yes, then what should the app need to do/present/communicate with us to achieve the best understanding of the site.
Curtin University awarded me ‘Humanities Journal Article of the Year 2019’ for my paper ‘Digital heritage interpretation: a conceptual framework’ that tries to answer these questions.

I have published an online #videotutorial (or course) on “Photo to 3D to AR: Free and Easy”. This course is designed for beginner to intermediate user, to show the process of creating detailed and accurate 3D models with texture using #Photogrammetry. Keeping in mind following this method, the users can save a large amount of time in 3D modelling with compare to manual modelling and texturing. I offered the course at #Udemy and it is completely FREE at https://www.udemy.com/photo-to-3d-to-ar-free-and-easy/
I spent a large amount of my spare time for planning, recording and in developing the course, and offered it as Free. Wondering, whether it could help others to learn #photogrammetry. I am surprised to see within 10 days, more than 1900 students across the world got enrolled !!! Also surprised, that two HOD from #CurtinUniversity have shown their interest to include this course under formal university modules.

I have been trying to understand head-mounted displays (#HMD); why they are for, their use? price? etc. From my understanding, first I have made a ‘poster’ and later a short brief video. As I am not a programmer or developer; this video reflects my own experience of using various HMDs, such as #BoboVR, #HTC Vive, Sony #PayStationVR, #FoveVR, #GearVR, #Meta2 and #HoloLens.
