DPA Pro - Collect data quickly within harsh environments

  Advances in high end professional digital cameras and software are revolutionizing industrial close range photogrammetry. The extreme portability of a handheld camera makes it possible to collect data quickly, and in locations where larger instruments are not practical. The simplicity of this system makes it one of the easiest metrology systems to learn and use. The DPA-Pro is the ultimate portable tool for analysis of how objects deform over time.

      The DPA-Pro industrial photogrammetry system has been optimized to make the best possible use of recent developments in professional digital camera design. Commercially available high end digital cameras have evolved to become components of first rate metrology system. Mass production of these cameras keeps cost down.

      Aicon selects specific camera models after rigorous testing.  Each camera is also fully tested and the characteristics of the optical components are mapped before the system is provided to the customer.

     

      Only cameras with very stable body construction, and consistent performance of the sensor componets are selected components.

    Aicon 3D Studio - Analysis software for 3D measurements

     

      AICON 3D Studio is an efficient control panel to the measurement modules. Data from AICON measurement systems such as DPA-Pro, ProCam and from other systems are recorded and processed. Features:
  • Graphic viewer allows easy visualization of measurement results.

    •  

  • Wide range of tools for comprehensive analysis of coordinate data.

    •  

  • Geometrical elements such as planes, spheres and cylinders can be obtained from the 3D coordinates and entities such as distances, angles can be obtained.

    •  

  • Calculations are accompanied by a wide range of statistical analysis that provides information on accuracy.

    • Scale Bar and Targets

     

      Photogrammetry measurements are naturally dimensionless. To scale a measurement, at least one known distance is needed. Using the certified calibrated distance of the scale bar within the DPA Pro kit, the distances between all points taken during photogrammetry measurements are computed. Coded and uncoded targets are available in many various sizes and may be non-reflective or reflective. Coded targets are used by the 3D studio software to “stitch” together all photographs taken during the data collection process. Uncoded targets can be easily adhered to the component being measured to report the 3D coordinate dimensional data of interest to the end-user.
  • Targets are available with magnetic or adhesive backings for fast placement

    •  

  • Adapters allow users to tie into coordinate system

    •  

  • Targets are automatically identified and the camera is calibrated during the computations to provide the best possible results.

    •  

  • Reflective targets make data collection possible in most lighting environments.

    Photogrammetry Principles

     

      Photogrammetry is the technique of measuring objects (2D or 3D) from photographs.  Photographs taken from two or more locations, can be developed from each camera to locate points on the object. These lines of sight intersect producing 3D coordinate since targets are being measured each time. Accurate deformation data can be collected even if points are moving independently.  During data collection, there is no need to touch the part.

    Targeting / Setup

     

      Proper planning is necessary prior to completing a successful measurement. Important information must be realized about the part in the measurement. Before starting a new Photogrammetry measurement, the following variables regarding the object must be taken into consideration; object visibility, shape and size, targeting capability and the level of accuracy required. Before photographing, targets are applied to the object. Reflective or non-reflective coded and non-coded targets are placed on and near the points of intent.

    Data collection

     

      Data collection is fast and easy.  The better the quality of the photographs (as to calibration of the camera, lens parameters and as to quality and image definition) the better the final model will be. The photos must overlap each other as the same places in the object must be seen in several photos.

    Analysis

     

      Photographs are directly imported into Aicon 3D Studio. The targets’ location in 3D space collected by the camera can be displayed as a 3D point cloud. All calculations are accompanied by a wide range of statistical analysis that provides information on the accuracy of the deducted geometrical elements and their reference sizes based on the achieved accuracy of the 3D-point measurement. The graphical representation of the results includes a differentiated representation of the individual results in color that allows the user to draw a fast and easy conclusion. The distinct representation of the complete project allows the user to control work already done and make changes if necessary.
