With the increasing demand for speed and accuracy in manufacturing inspections, the combination of one-click measurement and large/small field of view (FOV) switching in video measuring machines has become a key tool to improve efficiency.
One-click measurement means the operator only needs to place the workpiece and press the start button. The system automatically recognizes the workpiece position, calls the preset measurement program, completes the measurement, and outputs the results. This eliminates the tedious steps of manual positioning and parameter adjustment, greatly reducing human errors and speeding up the inspection process.
The large FOV mode uses dual telecentric lenses combined with high-resolution cameras to achieve a maximum coverage of 300×200 mm for rapid scanning. This allows capturing a large area in a single shot, reducing mechanical platform movements and significantly improving measurement efficiency, especially suitable for initial screening of batch parts.
The small FOV mode focuses on critical dimensions by using high-magnification lenses or localized high-definition imaging to ensure a measurement accuracy of about 3 microns. This is especially important for high-precision features such as electronic components and fine mold details.
There are two common ways to switch between large and small FOV: one is an automatic zoom lens, which is simple to operate but requires refocusing during switching; the other is a dual-camera system, which enables fast and seamless switching but requires more complex design and maintenance.
This strategy combining large-area rapid scanning and localized high-precision measurement balances efficiency and accuracy, suitable for production environments with multiple varieties, small batches, and different measurement requirements for various parts. Meanwhile, one-click measurement lowers the operation difficulty, allowing even non-expert operators to perform stable inspections.
In summary, this technical solution helps companies significantly improve inspection efficiency and production line responsiveness while ensuring product quality.
