#### Density Type: Column Sampling Rate

This is only available for Perceptron sensors.

Column Sampling Rate with Filter Type 'None'

Column Sampling Rate (CSR) is only available on Perceptron V5 and V4ix laser probes. CSR density is only available when scanning and not when the Auto Feature dialog box is open. This is due to CSR density not being acceptable for auto feature extraction since there are no edge points. In addition the Gray Sum locator type available from the Laser Pixel Locator Properties tab is incompatible with CSR. If Gray Sum is selected, the CSR option will be hidden from view. Also, note that if you are using Perceptron V5 on a portable device, Gray Sum is always selected.

Filter Type and Density Type can be used together. For example, you might want a “Long Line” filter with CSR density. However, in the case where you only want to apply the CSR density, the Filter Type should be set to "None".

CSR uses the following setting:

Regular Spacing (A): Provides the maximum distance (in pixels) that included points can be from each other along scanlines. The range of values is between 1 and 100. The minimum value of 1 will retain each and every column (i.e. 100% sampling). The maximum value of 100 will retain 16 points per full line with a V5 or 8 points per line with a V4i.
