Machine Vision Measurements
Using the ACC for machine vision testing according to EMVA 1288
As part of our partnership with AEON, we offer the AEON Camera Calibrator (ACC), a modular optical system designed to test machine vision cameras, based directly on the measurement parameters outlined in the EMVA 1288 standard (which is being adapted to ISO 24942). Parameters include linearity, noise, sensitivity, spatial inhomogeneities, and dark current. The authors of EMVA 1288 have used this solution to validate the standard.
Machine Vision Camera Testing
Improve the image quality testing of your machine vision systems
Machine vision systems are critical to numerous applications, including manufacturing, robotics, logistics, automated driving, and virtual reality. Because they are vital to our advancing society, these machine vision systems must be thoroughly tested during development to ensure high performance and safety.
Check out our blog post for more information about these cameras and the testing solutions we offer.
GEOCAL – Efficient Geometric Calibrations
Improving the efficiency of geometric calibrations
Proper geometric camera calibration is essential for systems tasked with detecting objects in a moving scene, e.g., ADAS applications. After calibration, the system more accurately detects and measures distances to objects in a scene.
GEOCAL offers a compact geometric calibration device that uses a beam-expanded laser in combination with a diffractive optical element (DOE), creating a much more efficient calibration method than the traditional checkerboard method.
GEOCAL benefits:
- Ability to generate a regular grid of light spots originating from infinity
- Measure geometric distortion, focal length, and principal point
- The camera position is translation invariant (to a certain extent)
- Efficiently manage the angle of camera rotation
- A compact design and no relay lens required
- Calibrate large field-of-view cameras
- Stereo camera alignments and adjustments
- Remove lens distortion using GEOCAL and OpenCV
Optimize your Image Quality Testing
Using multipurpose test charts for more efficient camera testing
A standard image quality evaluation typically involves assessing various image quality factors to determine a camera's overall performance. Factors such as camera resolution, texture loss, noise, dynamic range, color accuracy, and lens distortion have varying test specifications, requiring individual test targets.
Our TE42 multipurpose test charts combine multiple test targets on a single chart plane, allowing you to evaluate multiple image quality factors in a single test image and thereby significantly improving testing efficiency.
