The realistic interaction of real and synthetic content is an important part of creating a believable augmented reality. This augmentation may be as simple as rendering markers as if they are actually attached to physical objects, or as complex as adding 3D special effects to live video, but in either case the synthetic geometry must appear fixed to the same frame as the objects around it in order to be believable. The key to rendering geometry in a fixed frame is to maintain an accurate estimate of the camera position relative to the environment. Purely IMU-based solutions suffer from inaccuracy, and particularly lag, in the estimated position which results in synthetic geometry which appears to float over the real geometry. More fundamentally, however, the fact that no analysis is carried out on the captured image stream means that the system cannot know what is actually within the field of view of the camera. Thus, the system cannot take into account line of sight and must render synthetic content based only on viewpoint direction, rather than on the basis of the immediately visible environment. ACVT has undertaken a large body of fundamental research in this field and has several active projects looking at many different applications of the technology.
One of the Videotrace patent applications has just been accepted by IP Australia. It’s Patent Number 2007202157 ABSTRACT A method for generating a three dimensional (3D) model of an object is depicted in a two dimensional (2D) image is disclosed, The 2D image includes associated 3D information. The method includes an operator determining a geometric […]
We’ve loaded some Videotrace models on Sketchfab, a new 3D model sharing web site, which means you can embed them in web pages: Click on the model above to spin it around.

Pacific-Rim Conference on Multimedia (PCM) is a major annual international conference organized as a forum for the dissemination of state-of-the-art technological advances and research results in the fields of […]
Prof van den Hengel has been invited to attend the Australian Summit on 3D Multimedia, held in Wollongong in December 2011. This two-day event includes invited presentations by international and Australian experts from both academic research institutions and the industry. The Summit is the premier forum presenting the leading edge advances in 3D multimedia acquisition, analysis, […]
Prof van den Hengel will visit China’s National Laboratory for Pattern Recognition in early June to give a seminar and identify opportunities for collaboration. According to their web site The National Laboratory of Pattern Recognition (NLPR) at the Institute of Automation of the Chinese Academy of Sciences （CAS）, was established in 1987 to become one of the […]
Prof van den Hengel will give a seminar in the Qualcomm Augmented Reality Lecture Series at Technische Universität Vienna in July. The title of the talk is Reconstruction and recognition for realistic augmented reality and the abstract: Augmented reality involves the rendering of synthetic content into live video. The believable augmentation of reality requires that synthetic content […]
The paper Real-time Modelling for AR Applications won second prize in the best paper awards at the International Symposium on Mixed and Augmented Reality 2010 in Seoul, Korea. The paper describes a method for generating 3D models of objects which requires minimal user interaction. The motivation was the desire to allow users to create special […]
Well actually Anton van den Hengel gave a talk at the Max Planck Center for Visual Computing and Communication in Saarbreuken (Germany) about 3D User-Created Content (3DUCC). Anton was in Saarbrueken visiting the Computer Graphics Department of Max-Planck-Institut für Informatik there, and particularly the group of Dr. Thorsten Thormaehlen. Thorsten was instrumental in the development of Videotrace […]
Videotrace and Punchcard, the company commercialising it won the Research and Development category of this year’s South Australian iAwards. The iAwards are Australia’s premier technology innovation awards program. TheAustralian Information Industry Association (AIIA) has hosted the awards for 16 years, with this year’s awards sponsored by Fujitsu, KPMG, IBM, and Microsoft, amongst others.
Punchard, the company commercialising Videotrace, has been selected as one of the 23 ICT companies to participate in this year’s Tech23 event. Tech23 is run by Slattery IT, and offers 23 of Australia’s most innovative companies a five-minute time-slot to show off their business model to an audience of 400+ potential investors, mentors, entrepreneurs and customers.
