Target Features

The Imaging Gauge targets are available in three sizes to enable maximum ratio of target size to camera Field-of-View (FOV). The targets are identical, scaled version of each other which can all be used in conjunction with the APPLIED IMAGE GAUGE Software. Binary encoding is used to determine the target size automatically when analyzed.  The targets are mounted on rigid mounting board.  The pigment-based Munsell color patches and silver halide media are mounted with high quality adhesive to withstand difficult environmental conditions in field use.



Physical Components:

Targets have three major components: color accuracy patches, the mounting board and the resolution test feature.

Color Patches:  Pigment-based color patches using the gamut of the X-Rite ColorChecker® .

Mounting Board: Lightweight, 6mm. rigid board of expanded closed-cell polyvinyl chloride (PVC)

Resolution: High-resolution silver halide target includes visual and automatic analysis features



Color Features:

The color set included on Imaging Gauge™ targets is identical to those of the X-Rite ColorChecker® Classic target. These colors are a widely accepted standard in the industry. The pigment-based sheets are inspected, cut and assembled individually onto Imaging Gauge™ targets to ensure the most accurate targets possible.


Color palette definition is identical to the X-Rite ColorChecker® Classic target


Munsell color sheets are purchased from X-Rite and cut to size

X-Rite, the Munsell Color Laboratory, and APPLIED IMAGE, manufacture products in conformance to the accreditation practices and procedures set forth by the National Institute of Standards and Technology [NIST]. All production instrumentation and equipment is traceable to NIST. The X-Rite Munsell Color laboratory is an internationally recognized laboratory holding accreditations from ISO 9001 and ISO 2000.

Resolution Features:

Imaging Gauge™ targets incorporate three (3) human-readable features and one (1) machine-readable resolution feature to enable the correlation of automatic measurements to real-world image evaluations. The human-readable features include: an alpha-numeric feature, USAF 1951 feature and TV Lines. The machine-readable, slanted-edge feature is based on ISO 12233. All features are printed on high-quality ACCUedgeTM  reflected paper for durability and consistency.  ACCUedgeTM  reflected paper products are manufactured with extreme sharp edges capable of generating frequencies as fine as 20 cycles per millimeter (geometries of 2.5 microns) with very sharp edge gradients of under 1 micron.



Res-slanted-edgeSlanted-Edge feature is based on Applied Image QA-72 test target. The I3A/ISO Camera Resolution Chart conforms to the ISO-12233 standard, “Photography-Electronic still picture cameras – Resolution measurements”.





The USAF 1951 feature is based on the Applied Image T-21 target and conforms to MIL-STD-150A for resolving power tests.




The Alpha-Numeric feature is based on the Applied Image T-30 target. See the table included in the Theory Guide to translate group numbers to resolution.



The TV-Lines feature is based on the EIA-1956 Resolution Video Test Chart QA-70. For units conversion information, see the Theory Guide page on converting TVL to dpi and cycles/mm.
