3D data capture and evaluation

3DInspect enables 3D data capture and evaluation. The software is compatible with all 3D sensors in the Micro-Epsilon portfolio, including surfaceCONTROL for geometry, shape and surface inspection of matt objects; reflectCONTROL for measurement of shiny, reflective surfaces, and scanCONTROL sensors laser scanners for precise, inline 3D measurements.

3DInspect is designed for ease while offering a wide range of functions for analysing and measuring captured data. These include parameter setting of the sensors, alignment of point clouds and the selection of relevant objects, filters for smoothing and optimising point clouds, as well as calculation programs for height, radius and determining flatness and distances between points and angles. The software is able to find a target based on its contour and readjust it to allow further inspection to be made.

The 3DInspect software concept offers four steps to obtaining results:

1. Data acquisition – ensuring that the sensor and the target are correctly aligned aided by the ‘Display Image’ data. The data is then captured and processed into the software.

2. Data pre-processing – realigning of the captured data so that it is in line with the XYZ coordinate system.

3. Evaluation – the data can now be evaluated and various processes can be set up to inspect.

4. Transfer of data – the data can now be output from the software. This can be done in a number of different ways depending on the user’s configuration and set up. Available output formats are UDP, TCP and Modbus, where 3DInspect acts as the server. With additional modules, control and measured value output are also possible via Profinet and Ethernet/IP.

Glenn Wedgbrow, Business Development Manager at Micro-Epsilon UK, said: “For those system integrators with their own 3D processing software such as HALCON or similar, we offer our documented 3D Software Development Kit [SDK] with examples for various programming languages , so that they can create their own solutions to applications. For end users who do not have the capability to write their own software code, we offer the 3DInspect software solution.”

In addition to the standard version of 3DInspect, the ‘Automation’ function extension supports automated production processes. Video tutorials explain the software application and its features. As the software is constantly being developed, it is always up to date and every new release offers further useful functions. A comprehensive SDK is available for third party and custom image processing solutions. This is based on the GigE Vision and GenICam industry standards, including numerous function blocks.
