Measure parts automatically
Capture dimensions reliably, check tolerances, stabilize processes
In many production processes, dimensions need to be checked quickly, reproducibly and in a traceable way. Manual measurements are often time-consuming, error-prone or difficult to integrate into the running process. Dat-inf develops custom solutions to measure parts automatically, inspect tolerances reliably and make measurement results directly usable for downstream decisions in production.
Depending on the application, lengths, diameters, distances, positions, angles or other geometric features are captured automatically. The results can be documented, visualized and compared with limit values or target dimensions.
Typical tasks include automatic dimensional inspection, checking geometries and positions and evaluating parts and assemblies under real conditions.
Classify the measurement task quickly
Which features need to be measured – and which tolerances are relevant?
For a reliable automatic measurement solution, it is crucial to define which dimensions truly matter and under which real conditions measurement takes place. This distinction is often the most important first step.
- classification of measurement features, tolerances and borderline cases
- guidance on perspective, resolution, lighting and process stability
- recommendation for a feasibility study or pilot solution
Especially helpful are
- sample images or drawings of the parts
- a description of the relevant dimensions and tolerances
- information on cycle time, inspection rate and documentation needs
Even a few examples help narrow down the right technical approach. After receiving your inquiry, we will respond promptly with an initial assessment.
Typical measurement tasks
- Measurement of lengths, widths and diameters on parts and products
- Inspection of distances and positions of individual features or elements
- Inspection of geometries such as angles, contours and form deviations
- Comparison with target dimensions, reference geometries or defined tolerances
- Measurement in 2D or 3D – depending on the task and required accuracy
When automatic measurement is worthwhile
- When manual measurements are too slow or not reproducible
- When high volumes require consistent inspection quality
- When tolerance violations need to be detected early
- When measurement results must be documented in a traceable way
Solution: measuring parts automatically with cameras and software
An automatic measurement solution combines machine vision, camera technology and software into a robust measurement system. Parts are captured, relevant features are determined and evaluated against defined target values and tolerances. This creates objective and reproducible measurement results.
Depending on the application, measurement takes place inline in production or at a separate inspection station. This makes it possible to implement both sampling inspections and full 100% inspections efficiently.
Applications for automatic dimensional inspection in production
- Inspection of part geometries and contours
- Measurement of diameters, lengths and distances
- Inspection of positions and spatial relationships
- Inspection of form and dimensional deviations
- Series measurement with automatic documentation
- Inline measurement directly in production lines
- Evaluation of tolerance violations
- Measurement of complex surfaces or part features
Automatic measurement systems are useful wherever consistent quality, short inspection times and traceable decisions are required – from manufacturing and assembly to final inspection.
Practical example: measuring parts directly in a production line
In one industrial application, a camera-based measurement system was introduced to automatically measure parts directly in the line. Defined distances, contours and positional relationships at relevant features were inspected.
This allowed tolerance violations to be detected earlier, reduced manual measurement effort and improved process reliability. At the same time, better traceability was achieved because measurement results could be documented and evaluated automatically.
Technology behind automatic measurement
A camera alone is not enough for reliable automatic measurement. What matters is the right optics, stable lighting, correct calibration and software that fits the task. Only this interaction ensures reliable results in real operation.
- 2D measurement systems for classic dimensional and geometry inspection
- 3D systems for height information and complex surfaces
- Calibrated evaluation for reproducible real-world dimensions
- User interfaces and documentation tailored to the process
Depending on the task, compact inspection stations, integrated inline systems or retrofittable retrofit solutions may be appropriate. Dat-inf develops both the evaluation logic and the practical integration into existing workflows.
Further information is also available under Measurement Systems, Quality Inspection and AI / Machine Learning.
Benefits of automatic measurement systems
- Objective and reproducible measurement results
- Early detection of tolerance violations
- High inspection speed even with large volumes
- Traceable documentation of measured values
- Reduced manual measurement workload
- Integration into existing production and quality assurance workflows
Why Dat-inf for automatic measurement tasks
We do not develop off-the-shelf standard solutions, but tailored measurement systems for specific requirements. In doing so, we consider not only the algorithm, but also lighting, camera position, calibration, process stability and later operation.
Our focus is on robustness, traceable measurement criteria and practical integration. This creates a solution that works not only in the lab, but reliably in real operation over the long term.

Frequently asked questions about measuring parts automatically
Which features can be measured automatically?
That depends on the application. Frequently measured features include lengths, diameters, distances, angles, positions, contours or form deviations on parts and products.
Is 100% inspection possible?
Yes. In many applications, full inspection of all parts can be implemented directly in the process. Whether that is sensible and technically feasible depends on cycle time, imaging conditions, accuracy requirements and measurement features.
When is 2D measurement sufficient and when is 3D required?
For many classic dimensional and positional inspections, 2D evaluation is sufficient. 3D becomes relevant when height information, complex surfaces or spatial geometries need to be captured reliably.
Can existing measurement stations be expanded?
Yes. Many applications can be implemented as a retrofit solution when existing systems, inspection stations or production lines are to be modernized and expanded.
