Basic Concept of the Inspection Software

Evaluation workflow

Nominal data(CAD/STL = nominal part, measuring plans, FTA)

Actual data(meshes, point clouds)

Alignment of actual data to nominal data(RPS, 3-2-1, best-fit)

Comparison/inspection(surface, sections, coordinates, GD&T, tolerances)

Inspection reports(diagrams, tables, free viewer)

GOM Reference Point System

Strategies for transformation of single measurementsBoth variants can be used in the GOM software

Measurement Without Reference Points

Only possible with sufficient object geometry

No process reliability

Measurement with Reference Points

Also possible on continuous surfaces

Process-safe measurement strategy

Process Reliability in Measurement Operations

Dynamic Referencing

The combination of the stereo camera technology with GOM's reference point systemdelivers for each measurement an overdetermined system of equations.

Process Reliability in Measurement Operations

Integrated Monitoring

The combination of all these checks during the measurement leads to a process-safemeasurement strategy in the current measurement operation and ensures the accuracy ofeach individual measurement.

Unique transformationof single measurements

Measurement datacaptured without userintervention

Online tracking ofsensor position

Free positioningof part to sensor

Online monitoringof sensor/objectmovement andambient light

Prevention ofmeasurement errors

Online monitoringof sensor calibration

3-in-1 Sensor Concept

Right and left camera, each combined withthe projector

Three different views of an object during asingle measurement process

Measurement Results

Reduces the number of individual scans:faster overall measurement thanks to fewersingle scans, even on complex components

Improved measurement of shiny surfaces,through avoidance of 'hot spots'

Better measurement of deep pockets
