APPLICATION EXAMPLES

Nine ways to set up a camera test

These examples illustrate possible setups. Product photos show equipment references, and acceptance limits are defined for each project.

01 / 03

Image quality testing

Test how cameras respond to contrast, changes in illumination and low light.

EQUIPMENT REFERENCE

Automotive cameras

HDR response under high contrast

Challenge: Assess how a camera retains detail in bright and dark regions of the same exposure.
Proposed setup: Mount a calibrated transmissive step chart in a diffuse backlit lightbox. Shield stray light around the chart and fix camera position and capture settings.
What to verify: Check backlight uniformity, highlight clipping and the darkest steps that meet the selected signal-to-noise criterion.

EQUIPMENT REFERENCE

Consumer imaging

White balance across lighting presets

Challenge: Compare how consistently a camera renders neutral tones under warm and cool lighting.
Proposed setup: Illuminate a neutral chart with a tunable light source. Measure the color temperature and illuminance at the chart for each preset and use the same camera geometry.
What to verify: Compare the neutral patch RGB balance after the camera stabilizes. Record illuminance and exposure settings so the test can be repeated.

EQUIPMENT REFERENCE

Security cameras

Low-light image performance

Challenge: Find the lighting levels at which noise and loss of detail become significant for the intended use.
Proposed setup: Place a grayscale or detail chart in a light-shielded setup. Step the adjustable light source through measured illuminance levels while logging shutter time and gain.
What to verify: Compare patch noise and visible detail across the measured light levels. Record any clipping and the exposure and gain used at each step.

02 / 03

Geometric calibration

Choose target size, pose and mounting geometry for the camera’s working distance and field of view.

EQUIPMENT REFERENCE

Wide-angle & fisheye cameras

Wide-angle lens distortion calibration

Challenge: Capture enough identifiable points near the image edges, where distortion is often strongest.
Proposed setup: Arrange chart planes across a calibration chamber to cover the center and periphery. Capture multiple target poses using a lens model suited to the field of view.
What to verify: Compare reprojection errors by image region and inspect corrected images for residual curvature.

EQUIPMENT REFERENCE

Stereo & depth cameras

Stereo alignment and depth checks

Challenge: Calibrate the relative camera pose and verify that both views align after rectification.
Proposed setup: Mount a patterned target where both cameras can see the same features. Capture paired images at several distances and poses within the working range.
What to verify: Check vertical residuals after stereo rectification and compare estimated depths with known distances.

EQUIPMENT REFERENCE

Robot-mounted cameras

Robot hand–eye calibration

Challenge: Determine the transformation between a wrist camera and the robot tool frame.
Proposed setup: Fix a checkerboard or fiducial target on a rigid mount. Capture it from varied robot poses and pair each image with its recorded robot pose.
What to verify: Revisit reference points using poses excluded from calibration. Compare position and orientation errors with the task tolerance.

03 / 03

Module & production validation

Build repeatable optical stations for module evaluation and production checks.

EQUIPMENT REFERENCE

Lens & camera modules

Center and corner sharpness comparison

Challenge: Compare sharpness across the image field and identify asymmetric results that warrant further investigation.
Proposed setup: Mount an appropriate slanted-edge chart on a rigid stand. Control illumination, target alignment, distance and focus before capturing a series.
What to verify: Compare SFR or MTF metrics at the center and corners using the same analysis settings. Recheck mounting and focus if results are asymmetric.

EQUIPMENT REFERENCE

Image sensors & modules

Flat-field response and shading

Challenge: Separate illumination variation from camera shading when comparing module images.
Proposed setup: Use an integrating sphere source sized for the camera’s viewing geometry. Characterize the field first and capture unclipped frames at a fixed exposure.
What to verify: Review the light-source uniformity map alongside center-to-corner brightness and channel shading in the captured image.

EQUIPMENT REFERENCE

Camera production lines

Repeatable end-of-line camera checks

Challenge: Keep test conditions consistent when modules are changed between cycles or stations.
Proposed setup: Use an illuminated target assembly with a fixed working distance and defined module position. Store the lighting and camera settings for each test recipe.
What to verify: Measure setup repeatability with a reference module and compare selected image metrics across cycles and stations.
