The Advantages of Using an Industrial-Grade Camera for Image Analysis, Measurement or Medical Diagnostics

There has been a drastic improvement in consumer cameras over the last decade. As a result, people can now take incredibly impressive images with modern cameras, such as Point and Shoot cameras, DSLRs and even smartphones.

Performance attributes such as speed, resolution, color accuracy and low-light performance, have drastically improved, due to the extensive research and development efforts taken over the past several years. Any commercially available low-cost camera has the features to capture a stunning portrait, macro or landscape image effortlessly.

Advantages of Industrial-Grade Cameras

Since consumer-grade cameras are equipped with all such improvements, people may think that consumer-grade cameras can be considered as a camera solution by architects who are involved in the development of industrial vision systems. As a result, it is important to understand the features of consumer-grade cameras and the requirements of an industrial vision system.

The appearance of an image can be improved by consumer-grade cameras through manipulation of the image pixels subsequent to image capturing by the sensor. A specific improvement to the appearance of the image is the intent. Various common and/or proprietary software filters, including color/tone enhancements, gamma, brightness/contrast, blur and sharpen are used to achieve this improvement.

An anti-aliasing filter may be used in some cameras for the removal of image sharpness in order to avoid aliasing artifacts. After making alterations in the image, image compression is done into a more portable PC or web friendly format. However, the resulting image, whether compressed or raw, is not an accurate representation of the data initially collected by the sensor.

Conversely, an industrial vision system captures images with an objective of using the image for further analysis, such as pattern or color matching, measuring and medical diagnostics. In industrial cameras, the look of the image is not improved using hardware or software filters and the pixels are not moved around for increasing the compression ratio. As a result, industrial cameras will yield the same image. This means reliable, unaltered, usable images can only be obtained from cameras that are specially designed for industrial applications.

Industrial Cameras from Lumenera

Lumenera is involved in the design and development of superior quality industrial cameras. The implementation of a stringent quality control process allows Lumenera to ensure camera-to-camera consistency. Since the images taken are completely raw and unchanged, users can trust the information provided by the images for proper analytics.

Conclusion

Use consumer cameras for their intended purposes, such as for taking selfies and for capturing images of family vacations and pets. For industrial applications, such as image analysis, measurement or medical diagnostics, the ideal option is an industrial-grade camera.
