What is the difference between 2d and 3d Digital image correlation?

∙ 7y ago
3D Image Correlation provides full 3D coordinates of the surface of the material in test, using two camera stereoscopic view, which provides true deformation and strain data. 2D image correlation, uses one camera, providing relative displacement and strain data. As long as strain is greater than 1% and a longer lens is used, 2D can work well. 3D is much safer and more accurate.

How does a light sensor work?
A light sensor shines a light on the image to be scanned and collects the data as simple changes between black and white based on the level of reflection. These changes are later converted into digital form for processing.

Where can you find pictures of a complex machine?
Google provides a powerful image search function that one could use to find pictures of intricate machines.
What is the difference between induced and forced draft cooling tower?
Induced draft --- A mechanical draft tower with a fan at the discharge (at the top) which pulls air up through the tower. The fan induces hot moist air out the discharge. This produces low entering and high exiting air velocities, reducing the possibility of recirculation in which discharged air flows back into the air intake. This fan/fin arrangement is also known as draw-through. (see Image 3)Forced draft --- A mechanical draft tower with a blower type fan at the intake. The fan forces air into the tower, creating high entering and low exiting air velocities. The low exiting velocity is much more susceptible to recirculation. With the fan on the air intake, the fan is more susceptible to complications due to freezing conditions. Another disadvantage is that a forced draft design typically requires more motor horsepower than an equivalent induced draft design. The benefit of the forced draft design is its ability to work with high static pressure. Such setups can be installed in more-confined spaces and even in some indoor situations. This fan/fill geometry is also known as blow-through.
How does the rotary steam engine work?
The rotary steam engine has two identical lobed gears inside a tightly sealed casing to which each lobe of each gear is sealed often with a sliding vane to prevent slippage. One gear may be free spinning, it imparts its power to the other gear, the second gear (or both) drives a shaft which is often connected to a pump or pumps. The steam enters the engine at one side between the gears, it causes the gears to rotate and the steam moves outward around the periphery of the casing, expanding [due to the shape of the casing] as it pushes the gear lobes around to the exhaust side of the engine, where the steam is exhausted either to the atmosphere or a jet condenser, for reuse. Steam power fire engines typically used rotary steam engines. **See the attached Image below.
What is the difference between image processing and digital image processing?
Digital uses mega pixels ... vs film resolution is based on the area u have to record the image
What is the difference in image quality between Microfilm image and Digital image?
The difference is in perminance in case of Microfilm Image-More than 500 years but in case of digital image the media does not exist no longer than 15 or 20 years only. The cost of doing microfilm image is much more the cost of doing digital image.
What is the difference between a regular photo and a digital photo?
A digital photo is composed of information processed by a computer.
What is the difference in image clarity in digital image processing and optical image processing?
Digital image is depending on the camera resolotion, where optical image depends on the quality of the film. Normally an optical image will be better then a digital image, unless you are using high end digital camera. I hope this helps, Icko www.rtgallery.com
What is the difference between digital and optical zoom in a digital camera?
Digital just takes a small clip of the image and enlarges it while optical is just like if you stepped in closer to whatever you are photographing.
What was geometric concepts of qutab minar?
You do co-relate the geometric concepts in construction of qutab minar by using the Digital Image Correlation.
What is difference between digital image processing and digital signal processing?
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).
What is the difference between a tableau and a still image?
there is no difference. ;)
What is an tonal range?
The tonal range of a digital image is the number of tones it has to describe the dynamic range. These conceptual examples show that an image with a large dynamic range can have a narrow tonal range and an image with a low dynamic image can have a wide tonal range.
Difference between Digital image processing and computer graphics?
There is always a confusion among the newbies about the difference between Image Processing and Computer Graphics. Unless specifically mentioned , Computer Graphics is all about Synthesizing a new image from Geometry , Lighting parameters , Materials and Textures . The Emphasis is on Digital Image Synthesis. Image Processing is the process of manipulating an image acquired through some device . The image too often will be acquired from photographs,scanners , medical equipments. The emphasis is on Analysis and Enhancement of the image. Computer Vision is an area where Image Analysis is used a lot. Raster Operations dominate in the case of image processing. In the case of Computer Graphics , you will mix vector and raster operations to generate the final image.
What is the difference between the object and the image?
image larger than object
What is the difference between traditional photography and digital photography?
Traditional Photography records light from a camera on to film, digital records the light on to a light sensitive digital CCD that transferrs the image into data and records it as a digital file.
