How to Choose the Right Automatic Image Measuring Machine? IMAGE3 Selection Guide

Choosing the right automatic image measuring machine is critical for improving inspection efficiency, measurement accuracy, and production consistency.

Different manufacturers have different inspection requirements. Small precision components require high-resolution measurement, large parts require a wider field of view, and complex surfaces may require advanced optical configurations.

The POMEAS IMAGE3 series provides multiple configurations to help users select the right model based on:

1. Measurement size
2. Accuracy requirements
3. Part characteristics
4. Production environment
5. Automation requirements

1. What Should You Consider Before Selecting an Image Measuring Machine?

1.1 Measurement Size and Field of View

The first step when selecting an automatic image measuring machine is determining the required measurement area.

A larger field of view allows more parts or larger components to be captured in one image, improving measurement efficiency.

The IMAGE3 series provides different configurations for various inspection requirements, including:

Depending on the configuration, the IMAGE3 series can support measurement areas up to 300 mm × 200 mm.

2. Select According to Measurement Accuracy Requirements

Standard Dimensional Inspection

For general inspection tasks such as mechanical parts, plastic components, and incoming quality inspection, a standard image measurement configuration can provide efficient and reliable results.

High Precision Measurement

For applications requiring higher accuracy and repeatability, the optical system and image processing capability become critical factors.

The IMAGE3 series integrates:

1. Dual 20-megapixel CMOS cameras
2. Telecentric optical system
3. AI-based edge detection algorithms
4. High stability measurement platform

These technologies improve edge recognition stability and measurement consistency, especially for precision dimensional inspection.

3. Choose the Optical Configuration According to Part Characteristics

3.1 Standard Components

For conventional components such as screws, metal parts, and machined components, standard optical configurations can meet most dimensional inspection requirements.

3.2 Components with Height Differences

For parts with uneven surfaces or different heights, focus stability and depth of field become important factors.

The IMAGE3 series supports advanced optical solutions including:

1. Large depth of field optical design
2. Automatic focusing
3. Height measurement options

The IMAGE3 MAX can be equipped with an optional 8055 spectral confocal sensor for measuring product height and transparent material thickness.

3.3 Reflective or Complex Surface Inspection

For glossy metal parts, transparent materials, and reflective surfaces, proper illumination is essential for accurate edge extraction.

The IMAGE3 series provides:

1. Adjustable lifting light source
2. Multi-angle surface illumination
3. Coaxial illumination options

These lighting technologies help optimize image contrast and improve measurement reliability.
