(Press-News.org) University of Granada researchers have developed a 3D imaging system that scans 3D models of historical buildings using data obtained from an unmanned aerial vehicle (UAV)–an aircraft without a human pilot onboard. This is the first 3D imaging system to combine the use of UAVs, image-based 3D modeling technologies, and virtual representation of models to produce a realistic modeling of 3D objects from images.
The endpoint of this project is to obtain a 3D model of a historical building façade –as a cathedral–without any human intervention and at a lower cost than other technologies currently available (as 3D scanners). To date, UAVs have been used in many research fields, as they are fast and they can overfly abrupt areas, avoid large obstacles and provide information from multiple sensors.
No Scaffolding or Cranes
While UAVs autonomy is limited, they can descend for an operator to change the battery (an operation requiring just a few seconds), and then resume its task. This way, the object can be scanned in record time without the need for scaffolding or cranes.
As regards 3D-digitalization technologies, they can provide a realistic modeling of 3D objects from images obtained from sensors, stereoscopic cameras, multiple geolocated images obtained from different angles, etc. Finally, virtual reality technologies produce realistc high-quality 3D images (similar to those on 3D movies).
The multiple applications of this technology are evident, as they offer an autonomous device that in just some minutes can scan a façade with as much or a higher precision than 3D scanners. It is noteworthy that this device can get close to the object up to a few inches to obtain the smallest and unreachable details.
This project focused on façade 3D imaging is intended to prove the applicability of this new technology to any type of architectural model: buildings, monuments, etc. What these objects have in common is that digitalization is performed in vertical parameters and that objects are geolocalized.

Questions to Ask a Potential Personal Injury Lawyer
2012-05-23
When pursuing a personal injury lawsuit to seek compensation for injuries suffered due to another person's negligence, nothing will make more of a difference than your choice of a personal injury lawyer for your case. Do not be shy in asking questions of any potential lawyer. You may not have much chance during your first contact with a firm--they may dominate the questions--but when you actually get the chance, you need to be unflinching.
Areas You Want to Cover
When you are actually meeting with a lawyer, they have likely already decided they are interested in ...
Phthalates in PVC floors taken up by the body in infants
2012-05-23
A new study at Karlstad University in Sweden shows that phthalates from PVC flooring materials is taken up by our bodies. Phthalates are substances suspected to cause asthma and allergies, as well as other chronic diseases in children. The study shows that children can ingest these softening agents with food but also by breathing and through the skin.
Phthalates are a group of chemical compounds that occur in construction materials and a great number of common consumer goods such as toys, cleaning solvents, packaging, etc. Phthalates are suspected of disrupting hormones ...
Aggregating instead of stabilizing: New insights into the mechanisms of heart disease
2012-05-23
Malformed desmin proteins aggregate with intact proteins of the same kind, thereby triggering skeletal and cardiac muscle diseases, the desminopathies. This was discovered by researchers from the RUB Heart and Diabetes Center NRW in Bad Oeynhausen led by PD Dr. Hendrik Milting in an interdisciplinary research project with colleagues from the universities in Karlsruhe, Würzburg and Bielefeld. They report in the Journal of Biological Chemistry.
One defective gene is enough
Desmin normally forms stabilizing filaments inside of the cells. Different mutations in the DES ...
Porcelain Veneers
2012-05-23
Cosmetic dental problems can cause you a great deal of dissatisfaction with they way you look and the way you feel about yourself. Cosmetic dentistry provides an avenue for improving your smile, in a way that is uniquely tailored to your dental problems and smile wishes.
Porcelain veneers provide a way to achieve smile improvement in a relatively short amount of time. Instead of receiving orthodontic treatment for several months or even a couple years, porcelain veneers can create a straight, symmetrical smile within weeks.

Forensics ferret out fire beetle secret
2012-05-23
Criminal cases can often only be solved using forensics to piece together physical evidence and reconstruct what happened. Prof. Dr. Helmut Schmitz from the Institute of Zoology at the University of Bonn and Dr. Herbert Bousack from the Peter Grünberg Institut at the Forschungzentrum Jülich went through the same experience. Prof. Schmitz has been researching fire beetles of the genus Melanophila and their sophisticated IR sensors, which these pyrophilous insects use to detect forest fires, for many years. This is a very special ecological niche. "It allows the beetle larvae ...
Cataract Surgery Recovery
2012-05-23
Your recovery from cataract surgery will depend on factors such as your body's natural healing ability and how closely you follow your eye surgeon's advice. Taking time to carefully follow all postoperative directions will help guard against potential complications and ensure your cataract surgery is successful.
Postoperative Considerations
Following your cataract surgery, your eye surgeon will provide you with a complete list of things you will need to do to help guarantee a swift and complication-free recovery. This list will include things such as:
- Use all ...
Economic power of self-employment felt countywide
2012-05-23
People in rural counties who work for themselves may add a boost to local economies, improving income and job growth, according to economists.
The share of self-employed workers in non-metro counties significantly predicted personal income and job growth, as well as declines in family poverty levels, said Stephan Goetz, professor of agricultural economics and regional economics, Penn State, and director of the Northeast Regional Center for Rural Development.
"We often look at self-employment as a stopgap measure, something done out of desperation," Goetz said. "But, ...
Carnegie Mellon brain research shows visual perception system unconsciously affects our preferences
2012-05-23
PITTSBURGH—When grabbing a coffee mug out of a cluttered cabinet or choosing a pen to quickly sign a document, what brain processes guide your choices?
New research from Carnegie Mellon University's Center for the Neural Basis of Cognition (CNBC) shows that the brain's visual perception system automatically and unconsciously guides decision-making through valence perception. Published in the journal Frontiers in Psychology, the review hypothesizes that valence, which can be defined as the positive or negative information automatically perceived in the majority of visual ...
PRK, LASEK, and Epi-LASIK
2012-05-23
PRK, LASEK, and epi-LASIK are all Laser Vision Correction procedures that involve temporarily removing the topmost layer of the eye, called the epithelium. This sheet of cells rests over your cornea and must be removed in order to reshape the cornea using laser energy. Once the laser surgical procedure is complete, the epithelial sheet is usually placed back over the surface of the eye, and a soft "bandage" contact lens is inserted into the eye to help the flap heal.
While these three procedures share basic similarities, they differ in a few key ways that are ...
Study shows how to keep a Mars tumbleweed rover moving on rocky terrain
2012-05-23
New research from North Carolina State University shows that a wind-driven "tumbleweed" Mars rover would be capable of moving across rocky Martian terrain – findings that could also help the National Aeronautics and Space Administration (NASA) design the best possible vehicle.
"There is quite a bit of interest within NASA to pursue the tumbleweed rover design, but one of the questions regarding the concept is how it might perform on the rocky surface of Mars," says Dr. Andre Mazzoleni, an associate professor of mechanical and aerospace engineering (MAE) at NC State and ...
