Hikrobot MV-CL line-scan cameras
Continuous inspection, built line by line
A Hikrobot line-scan camera captures one narrow image line at a time while the material moves. Successive lines form one continuous image of film, paper, foil, coils, glass or long profiles.
Line format
4K, 8K and 16K classes
Image output
Mono or color
Interfaces
GigE to CoaXPress
Resolution across the web and sampling along the motion are selected separately.
From application to image
Define the image before choosing a model
Line scan starts with the application. Material width and the smallest relevant feature determine the pixels required across the web. Transport speed and the required sampling along the web determine the line rate.
Two sizing relationships
Across the web: field width ÷ pixels per line = object-space sampling.
Along the web: transport speed ÷ line rate = distance per line.
If the complete part fits in one field of view, an area-scan camera is usually the simpler option.
01 · Geometry
Width and smallest feature
Calculate the required sampling across the material and select the corresponding line format.
02 · Motion
Speed and encoder
Use material displacement to trigger each line when speed varies or slip affects image geometry.
03 · Exposure
Line light and contrast
Fit the exposure inside the line period and provide enough light to preserve contrast at production speed.
04 · Data path
Interface and processing
Match the interface and vision PC to the throughput created by line format, line rate and bit depth.
34 active configurations
Hikrobot MV-CL line-scan camera family
The sizing step produces a required line format and line rate. MV-CL then offers documented 4K-, 8K- and 16K-class configurations for mono or color acquisition, with interfaces from GigE to CoaXPress.
Line rate, pixel size, lens mount and interface availability vary by SKU. Selected documented models reach up to 80 kHz, so the exact operating mode must be verified for the chosen configuration.
Line format
Select enough pixels across the field width to resolve the smallest relevant feature.
Mono or color
Use mono for intensity and sensitivity; choose color when color differences carry inspection information.
Interface
Match throughput, cable architecture and host hardware. Optics and lighting remain separate design choices.
Where line scan fits
Continuous material and long surfaces
Line scan is effective when product length is not a practical frame boundary. The camera captures one line and controlled motion supplies the second image dimension.
Film, foil and paper
Inspect continuous webs for surface, edge and print-related defects.
Print and labels
Build a continuous image for registration, print quality and missing-content checks.
Coils and long profiles
Maintain consistent sampling over products that extend beyond one conventional field of view.
Glass and flat material
Combine stable transport and line lighting for uniform surface coverage.
A complete line-scan system
Motion
Encoder quality, transport stability and slip affect image geometry.
Optics
The lens must cover the long sensor with sufficient resolution and focus.
Lighting
Focused line lighting must provide contrast within the available exposure time.
Processing
Interface, host memory and algorithms must keep pace with the data stream.
Technical background
Compare the imaging methods
Learn how line images are formed and compare line scan with area scan when motion and field of view leave both options open.

Short answers about image formation, line rate, color and interface selection.
Application sizing
Turn application data into a camera choice
Share the material width, smallest relevant feature, transport speed, surface properties and installation space. Sedeco calculates the line format, line rate and data throughput, then selects a matching camera, lens, lighting and processing path.
