The Case Of High-Resolution Industrial Cameras

In high-resolution industrial camera systems, the function of the industrial camera is to capture the image projected on the sensor through optics in order to transfer it to an electronic system.

The high-resolution industrial cameras offer complete control of times and signals, shutter speed, and other fundamental factors when integrating them into an artificial vision system in scientific and industrial applications.

How To Choose High-Resolution Industrial Cameras?

The selection of the right industrial camerasis a decisive aspect in determining the performance and quality of the vision solution. The factors to consider are sensor performance, camera features, and image transfer and interface technology.

3 Keys To Choosing The Most Suitable High-Resolution Industrial Cameras 

The growing interest in high-resolution industrial cameras stimulates the market and increases supply significantly. However, the lack of information or ignorance about these solutions hinders the ability to discern between products. We explain the concepts you must be clear about before deciding on anindustrial camera suitable for your needs.

High-resolution industrial cameras can become the solution for companies to open their doors since they will most likely be one of the requirements for their opening. However, the growing supply of this type of solution on the market, including the presence of low-cost products whose features are not always the most appropriate, makes it difficult for customers without experience in thermography to choose.

So, what are the main aspects we must consider when choosing a thermal imaging camera for access control?

Installation Conditions And Environment Are Crucial.

Regardless of the type of industrial cameras we choose, suitable for each space, we must take into account the environment in which the shot is taken and where the temperature control point or points are to be installed. Environments affected by high/low temperatures could falsify the results. For this reason, it is recommended that the temperature be taken in stable environments and not outdoors.

Sensor Sensitivity Is Not The Same As Temperature Measurement Accuracy

The sensitivity (Temperature Sensitivity) is the minimum temperature variation that high-resolution industrial cameras can detect. On the other hand, precision or accuracy is the maximum difference that can exist between the measurement obtained by the camera and its actual value. 

Accuracy depends on variables such as:

  • Camera calibration
  • The presence or not of a black body (Black Body)
  • Control of the type of installation
  • The type of measurement (Free Flow, One by One)
  • Room temperature control (indoor or outdoor)

Industrial Camera Resolution 

Some solutions on the market measure temperature. This measurement is imprecise, as the body is affected by a wide range of environmental and physiological factors and does not accurately correlate with core body temperature. The idea is to have a resolution of 200 pixels in the eyes’ field of vision (minimum 5√ó5 px for every 10 mm). Taking into account that the resolution influences the maximum distance to obtain an accurate measurement, it is advisable to perform measurements while standing without glasses or hats that affect the field of vision.

Self-Calibration By Actual Temperature Reference (Black Body)

The margins of error/precision in the measurement of temperatures can lead to measurements fluctuating between 2C and 3C concerning the actual measurement. Using an absolute temperature reference allows us to self-calibrate the system and continually improve the error margin. This is possible thanks to an element called the black body. With this equipment, an objective, precise and continuous temperature measurement is obtained within the field of view of the high-resolution industrial cameras. Therefore, we need to increase the accuracy of the measurement.
