Professional hand 3d-scanners Bashny.Net

According to a survey in the article «How I using 3d-scanner forged key» I decided potestit and describe the professional handheld scanners 3d-( not often hold in your hands a piece of plastic cost above one million rubles).

The three-dimensional or 3D-scan - the process of translating the physical form of the real object, the product in digital form, i.e. a three-dimensional computer model (3d-model) object.

3D-scanning may be useful in solving problems of re-engineering, designing fixtures, tooling, spare parts in the absence of an original computer product documentation, and if necessary digitize surfaces of complex shape, including artistic forms and molds.

Job scanner is a bit like a person's vision surround. As the brain is building three-dimensional image seen as 3D scanner receives information by comparing two images that are displaced relative to each other. To achieve the required accuracy of a model subject to additional technological methods in the form of laser illumination or periodic outbreaks.

Under the cut description and test drive Creaform HandyScan 700 and a bit about the other 2 scanner and one eye pro Surphaser. As well as examples of the use of scanners in the oil and aerospace industries, medicine, and reverse engineering.

Steps for creating 3d-model using scanner
3D-scanning - a tool for quick geometry of three-dimensional object of almost any complexity. However, we must remember that the 3D-scanner gives a cloud of points in three-dimensional space, arranged in the form of an object or a polygonal model - the same points, but connected by lines so that we obtain the set of intersecting planes that describe the geometry of the object.
The geometry of the object very few people want, because it is often the purpose 3D-scanning - is accurate drawings of the scanned object, not just the coordinates in three-dimensional space.

But this issue has long been solved: the market is of special software such as Geomagic DesignX, allows you to turn the point cloud into a parametric model and pass it to absolutely any CAD-system.

That is, with this software, we remove any restrictions at all: 3D-scan scanner object parametriziruem it in a special software, the resulting share your parametrics or NURBS surfaces (whatever) in your CAD and easily work on editable model, getting drawings any cut in the required format.

Application h4> «At the moment, three-dimensional scanning is applied not only to obtain the digitized models of different items, figurines, car body and so forth. 3D-scanning is also widely used in scanning people, and lately it's especially asks technology it's interesting to keep not only within the family photos on the nightstand, but also, for example, the entire family, printed on the 3D-printer. Besides entertainment purposes in medicine are increasingly used three-dimensional technology. For example, scanning the person's feet to create a comfortable prosthesis scan snapshot of the jaw of the patient for further work in specialized dental software scan of a person ... as it may seem at first glance, at the moment 3D - technology carry entertaining, but it has long been not. This innovation in virtually every sphere of activity. » Alex Specialist Consistent Software Distribution i>

Severe technicians inspect pipeline
assessment of pipeline integrity

aircraft hail damage assessment The impact injuries to hail on the aerodynamic characteristics of the aircraft is a difficult factor to assess, but at the same time, in the literal sense of the word - it is vital! - Make this estimate as accurately as possible. The shape and size of defects may vary depending on the strength of the squall, which falls in a plane. Consequently, the most common method of analyzing injury - by measuring the geometry (length, width and depth) of each dent from the land surface of the aircraft. There is also a need to control the geometry of items on a production line.

internal inspection of pipes The pipeline operator is always torn between ensuring public safety and economic consequences of digging in areas where, as it turns out in the future, the repair is not required. Direct assessment methods are used to confirm the results of the measurements obtained with the tools to check the internal condition of the pipes. These tools are not always accurate, and sometimes it requires recalibration. Service companies are spending a lot of time on the comparison of data from suppliers of equipment for internal inspection of pipes and the data obtained by means of the transmitter (or any other instrument for direct assessment), to evaluate the performance of the instrument. For proper evaluation of the tool checks the internal state of the pipe pipeline operators must perform an annual analysis of statistically significant populations using the device, which provides greater accuracy than the technology of magnetic flux leakage.

inspection and measuring tanks Public concern over environmental issues is forcing oil companies to improve safety in relation to the environment and health. Inspection of tanks has traditionally been a lengthy procedure, but now the company can satisfy the public interest due to the three-dimensional scanning technology, to improve the accuracy and efficiency of these operations. The same tool can be used for other purposes, for example for measurement reservoirs. In fact, the construction of the exact capacity of the table is a major industry requirements ...

Installing the tank h5> Reports on the inspection of tanks, a system generated Creaform, contain important information - such as the bottom of the profiles, vertical profiles and kruglogrammy - needed to assess the sedimentation tank.

Construction of the calibration tables of capacity h6> Graduation capacity tables are used to determine the amount of product in the tank. Report form can be changed in accordance with the needs of the client. The data in this report may or may not include the volume of the internal tank structure, the influence of parameters on the floating roof tank etc.

3d-modeling method for the control of phased array h5> for the aerospace industry The service aircraft and their components and structures necessary to monitor and assess the level of degradation and remaining life. The aircraft carriers and face the problem of control of complex components (such as gas turbines, engine compartments, fairings, cab pilot, etc.), which are often very complex parts and can not be removed for inspection. To solve this problem, usually referring to a method of controlling a phased array.

Simulation of phased array focal law used to predict the results of the control and optimization of the configuration of the sensor and the wedge. Control components of complex shape using two-dimensional array can be challenging. For lack of a better solution, 3D-model is usually taken from a CAD file or from a theoretical model of the structure. However, the actual shape of the component is different from the ideal theoretical model, and hence degrades the accuracy of ultrasound scanning and detection probability.

for Energy

Components and construction of power plants is necessary to monitor and evaluate the level of degradation and remaining life. Energy companies are faced with the problem of control of complex components (parts "dovetail", nozzles, feed pipes, etc.), which are often very complex assemblies and can not be removed for inspection. To solve this problem, usually referring to a method of controlling a phased array.

Simulation of phased array focal law is widely used, particularly in the nuclear industry, to predict the results of control and optimization of the configuration of the sensor and the wedge.
