ISO 12233 Standard Image Resolution Test Card 2000 Line

ISO 12233 Standard Test Card 2000 Line

The core basis of the ISO12233 resolution test card is the international standard ISO 12233:2000 "Photography - Electronic still image cameras - Resolution measurement", which unifies the resolution measurement methods and judgment specifications for static electronic imaging equipment, and solves the industry Challenge of the lack of interoperability and comparability of resolution detection data in different devices and scenarios.

Product Features: Compliant with international standards, offering Data reports, and customizable.

Chart: Introducing the latest generation of high-precision microjet printer, with optional reflection and transmission effects, and customizable sizes; ISO12233 capable of achieving 8x 4000 lines without stitching, with precise grayscale and excellent Lambertian characteristics.

Applicable scenarios: Comprehensive calibration of machine vision systems (initial calibration, system-level performance evaluation, and acceptance of industrial vision systems), selection and comparative testing of cameras and lenses, etc.

The ISO12233 image resolution test card is mainly divided into two categories: standard type and enhanced type. The standard type is a universal product in the industry, and its structural design revolves around the core requirements of resolution detection, forming a fully functional testing unit system. The core components and functions are as follows:
(1) Basic materials and core line structure
The core imaging unit of the test card is made of high-precision radiation absorbing material, with lead foil or equivalent lead equivalent metal foil as the core substrate. The thickness of the grating is controlled between 0.05m and 0.1mm, and micro level precision line forming is achieved through laser engraving technology. The core detection unit is based on line pairs (LP) as the measurement unit. A grid bar and adjacent equidistant lines form a line pair, and multiple sets of line pairs are arranged in an orderly manner according to an equal ratio/equal difference sequence. The distance between adjacent line pairs is fixed at 3mm, and the whole is clamped in a high transparency organic glass plate to ensure imaging stability during the detection process.
(2) Core Resolution Testing Unit
The core wedge diagram testing unit of the test card covers a testing range of 100-2000LW/PH (line width per image height), with each unit performing its own duties to achieve accurate detection of full screen resolution:

J1 and K1 units: covering a testing range of 100-2000LW/PH, specifically designed to measure the horizontal visual resolution at the center of the image;
J2 and K2 units: Covering 100-2000LW/PH with the same measurement range, used to measure the vertical visual resolution of the center of the image;
JD and KD units: covering a testing range of 100~1000LW/PH, used to measure visual resolution in a 45 degree oblique direction;
Four corner cross shaped testing unit: covering a range of 100~1000LW/PH, used to detect the horizontal and vertical visual resolution of the four corners of the image and evaluate the imaging performance of the lens edge.
