Application study · Packaging and handlingPackage outlines: separate a bright carton face from its background
A rectangular shadowless light gives this carton face a strong boundary in the real source capture. The useful decision is where the outline lies; the image says nothing about what is inside the box.
Locate the package from a defined contour rather than its printed graphics.

Proposed component
MV-CS050-10GM(NPOE)
Proposed 5 MP monochrome global-shutter camera, 2448 × 2048 pixels at 3.45 µm, C-mount. The source camera is unidentified. This NPOE model requires separate power and does not support PoE.
Proposed component
LS-KF1628M-ML
16 mm C-mount macro lens. Its printed 0.1x / 152 mm working-distance pair gives a derived 84.46 × 70.66 mm field on the proposed camera. Confirm focus, coverage and fixture clearance.
Tested component
LS-RIH15075
White rectangular shadowless light named by the source. Printed housing 200 × 116 × 42 mm; drawing inner opening 147 × 72 mm.
Proposed component
LS-BT-XZ-G-6-6045
600 mm column, 600 × 450 mm breadboard, glass tray and two lighting holders. Proposed bench fixture; actual load, travel, clamps, mounting fasteners and light clearance must be confirmed.
Inspect the real capture
Follow the contrast to the part.
Locate the package from a defined contour rather than its printed graphics.
Camera and available lens CAD are published models. Light envelopes and the station base/height use printed dimensions. Part shapes, brackets, holders, shielding and spacing are illustrative; they are not reconstructions of a source part or a complete mechanically validated assembly. Light paths explain the proposed arrangement and do not simulate optical performance. The proposed field is derived from the printed camera pixel dimensions and the stated lens magnification/working-distance pair, not measured from the source capture.

The station is an optical test bench, with its two lighting holders included in the catalog listing. The 3D column and base follow the published height and footprint. Carriages, clamps and part supports are schematic: confirm camera screw pattern, lens support, light fasteners, permissible load and actual travel before ordering.

Select a controller against the exact light voltage, drive mode and power, then confirm camera data/power/I/O cables and a suitable PC. These are not silently added to the proposed optical kit.
Lighting application-lab image sheet
Evidence you can inspect
Visible in the images
A rectangular package face is clearly separated from the surrounding background.
What the source reports
The sheet describes extracted high-contrast contours with white LS-RIH15075; it gives no positional error, tolerance or production detection rate.
How to use this evidence
An application-lab lighting demonstration, not a customer deployment or a qualified production inspection. Proposed camera, lens, fixture and scene spacing require a fresh trial. Source observations do not establish a defect-size limit, accuracy guarantee or production false-call rate.
What the camera saw
Cropped from the source test sheet; original test annotations are retained. Captures are not generated or enhanced. Drag the comparison slider or use the image buttons.
The challenge
A light-coloured package can merge into a bright fixture or background. Printed text and glossy wrapping can distract a detector that only needs the outside contour.
How it was solved
The source names white LS-RIH15075. The result crop retains the package outline while excluding the unrelated brand and label on the source part photograph.
The proposed camera and macro lens look through the frame. The individual light drawing gives a 147 × 72 mm inner rectangular opening; the 152 × 76 mm emitting area is a separate dimension.
Why it works
- 1
A diffuse surrounding field makes the package face distinct from its surroundings.
- 2
A clear outside edge supports a location trial; it does not prove packaging seal quality, contents, correct printing or a dimensional tolerance.
From image contrast to a production decision
What to validate on your part
A useful sample image is the starting point. These are the checks that turn the concept into a defensible inspection.
- 01
Specify the outline
Define whether the box edge, wrapping seam or printed border is the required datum.
- 02
Vary packaging
Include acceptable carton colours, glossy film, dents and background changes.
- 03
Repeat location
Measure detected edges across fixture reloads, rotations and the required working field.
Explore your inspection requirementsNo limit from motion
How many pixels cover your feature?
Compare feature coverage, camera pixel requirements and exposure using your own planning inputs. These are calculated planning values, not inspection results or an accuracy specification.
Editable planning scenario. Adjust these example inputs for your application; they are separate from the source test and 3D setup. Motion allowance and target coverage are starting points to validate, not acceptance limits. Pixel count starts from the proposed camera's catalog resolution.
Enter finite numbers in every field. Field width, feature width, target coverage, exposure and allowed motion must be greater than zero; horizontal pixel count must be a positive whole number; material speed may be zero. Use values within the supported numeric range if a calculation cannot be represented.
Object sampling mm/px
Pixels across feature px
Horizontal pixels for target px
Motion during exposure px
Exposure ceiling from motion µs
Formulas and assumptions
The field, feature, speed and exposure start with neutral example values. They are not taken from the source test or the 3D illustration. Allowed motion starts at an editable 0.5-pixel example; it is not a recommended acceptance limit. Target coverage starts at an editable 5-pixel example; it is not a recommended detection or measurement threshold. The horizontal pixel count starts from the catalog Resolution row for MV-CS050-10GM(NPOE). Use the effective width after cropping, binning or decimation if those modes are enabled.
- Object sampling (mm/px) = field width (mm) / horizontal pixels.
- Pixels across feature = feature width (mm) / object sampling (mm/px).
- Horizontal pixels for target = field width (mm) × target pixels across feature / feature width (mm), rounded up to a whole pixel.
- Motion (px) = speed (mm/s) × exposure (µs) / 1,000,000 / object sampling (mm/px).
- Exposure for allowed motion (µs) = allowed motion (px) × object sampling (mm/px) / speed (mm/s) × 1,000,000.
The exposure result is the maximum duration from this motion allowance alone. At zero speed, motion sets no exposure limit; the camera, lighting, saturation and other constraints still apply. A shorter exposure does not itself guarantee a reliable inspection.
Field width and feature width refer to the same object plane. The motion calculation assumes uniform linear motion parallel to the field-width direction and a single exposure. It does not model perspective, vibration, rolling-shutter distortion, diffraction, defocus or optical distortion. A strobe may change the effective exposure.
The target result is a horizontal sampling requirement, not a camera recommendation or a change to the selected camera. It uses the effective image width after cropping, binning or decimation and does not determine the vertical resolution or sensor size. Pixel coverage alone does not establish detectability or measurement accuracy. Validate contrast, lens performance, working distance, illumination, calibration, camera exposure limits and the inspection algorithm on representative parts. Changing field width does not change the 3D model or certify that the proposed lens can achieve that field.

About this case study: the photos and camera images come from the application laboratory of the maker of the lighting and optics we sell, imaged on the parts shown; your results depend on your part, camera and set-up. This is an application-lab study, not a LumaSpec customer deployment. Source figures are reported results; proposed components require a fresh trial. The 3D scene illustrates the arrangement and does not simulate imaging performance.
