  • Page 40: Selecting A Colour Palette

    LWIR Thermal Imaging Camera 5.9 Selecting a Colour Palette The LWIR Web Server has a range of colour/greyscale palettes available. You can select which colour/greyscale give you the best results for your particular application. To select a palette, click on the colour/greyscale to the right of the thermal image. A pop-up window displays the range of available palettes. Click on the required palette to activate it. The thermal image is displayed using the new palette. 5.10 Adjusting the Temperature Span By default, the LWIR Web Server colour/greyscale palette covers the entire temperature range of your LWIR Thermal Imaging Camera - either 0 to 500°C, or 100 to 1000 °C. However, your application may have temperatures which are well within these lower and upper limits. You can adjust the temperature measurement span limits as follows: On the grey vertical bar to the left of the palette, drag the upper and lower temperature limit setting boxes to match the temperature span you want to measure e.g. 200 to 400 °C. The values displayed at the top and bottom of the palette are adjusted to match your span settings, and the thermal image will be updated to use these values.

  • Page 41: Time Function Processing

    Thermal Imaging Camera LWIR 5.11 Time Function Processing The LWIR Web Server software contains a number of Time Function algorithms which help deliver a more consistent temperature reading from a sometimes noisy, changeable reading from the LWIR thermal imager. The following sections help you choose and configure the time function most appropriate for your application. 5.11.1 None The Web Server will display the raw output from the LWIR thermal imaging camera. 5.11.2 Averager Refer to Fig. 4-2. The Averager time function can be used to ‘smooth’ the temperature output signal in relation to the temperature input. The Averager response can be adjusted to suit your application. With a fast response speed, the temperature output signal tracks the input signal closely, any rapid fluctuations in the input are reflected in the output. With a slow response speed, the temperature output signal is much smoother, displaying more the ‘trend’ of the input signal rather than rapid changes. Fast averager response speed Slow averager response speed Time Fig. 5-4 Graphical representation of the Averager time function Installation Guide 5 - 13...
  • Page 42 LWIR Thermal Imaging Camera 5.11.3 Peak Picker The Peak Picker function can be used to monitor the highest temperature measured in the thermal image (or ROI). This feature is useful especially for moving targets and/or where the target is obscured partially e.g. a steel slab on a rolling mill where parts of the surface are covered with scale. The ‘clean’ area will be at the higher (i.e. true) temperature. The Peak Picker used in the LWIR Web Server processors has the following features. Threshold level Temperature above which the Peak Picker is active, used in conjunction with the ON and OFF delay. ON delay Time period between the temperature rising above the threshold level and the Peak Picker function switching on. OFF delay Time period between the temperature falling below the threshold level and the Peak Picker function switching off. In ‘Hold’ mode, at the end of the ‘OFF’ delay, the temperature output value is held constant until the temperature input next rises above the threshold level. In ‘Reset’ mode, at the end of the ‘OFF’ delay, the temperature output signal falls to ‘under-range’ until the temperature input next rises above the threshold level. In ‘Sample’ mode the peak picker samples for a pre-defined period, then outputs this value. Decay rate A user-adjustable value at which the stored temperature output signal decays. The Peak Picker function can be reset via the CMD (Command) input.
