Selecting the appropriate industrial camera for your machine vision system from the outset can prevent expensive redesigns or upgrades later on. But how do you determine the best camera? The answer lies in understanding your specific needs. Let’s break this down step by step.

Step 1: Define Your Requirements

Begin by identifying the key parameters essential for your system. For instance, if your application requires high contrast images, you’ll need a camera with a high dynamic range. Other factors to consider include resolution (e.g., 4 megapixels), frame rate (at least 150 frames per second), and interface type (e.g., Camera Link). Additionally, if multiple images are used for a single measurement, global shutter technology may be necessary to minimize image-to-image variations.

Once you’ve narrowed down your criteria, such as selecting cameras based on a specific sensor like the CMOSIS CMV4000, comparing specifications across suppliers can become challenging. Even cameras with identical sensors may display different values for parameters like dynamic range due to varying measurement methods or conditions. To address this inconsistency, industry standards like EMVA 1288 have been developed for standardized comparison. However, not all manufacturers adhere to these standards, leading to discrepancies in reported data.

Step 2: Consult Experts and References

If your list of potential cameras remains extensive, seek input from colleagues or industry professionals through platforms like LinkedIn groups. This can help refine your options further. Additionally, evaluate the reliability and reputation of camera manufacturers by researching their track record for delivering consistent performance and long-term support.

Step 3: Prepare for Evaluation

Before diving into evaluations, create a checklist to ensure your long-term relationship with suppliers aligns with your needs. Consider factors such as technical support, quality of service, and the supplier’s commitment to serving your market. Once this groundwork is laid, you’ll likely have a manageable list of 3–5 candidates ready for testing.
