Basic concept of image stitching: individual measurements are combined to form an overall image
LMK Image Stitching: Efficient measurement of ultra-wide displays with intelligent image fusion.
Measure and evaluate Displays with unusual aspect ratios easy and fast
Why image stitching?
Modern ultra-wide displays (e.g., 21:9, 32:9, or 6:1) push conventional measurement systems to their limits: sensor surfaces are used inefficiently, resolution is insufficient, and measurement gaps occur. With LMK Image Stitching (part od the display package), TechnoTeam provides a powerful extension for high-resolution luminance measurement of displays with large or unusual aspect ratios. Several individual images are merged into one seamless, high-resolution overall image, without any loss of measurement accuracy.
How LMK Image Stitching works
With LMK image stitching, several individual images are captured and merged into a continuous, high-resolution luminance image. This is done sequentially or in parallel with several cameras. The algorithm is based on our Advanced Pixel Registration (APR) method. It separates the position detection from the luminance measurement and allows distortion-free measurement directly on pixel-level.

Advantages of combined stitching and APR technology:
- Higher resolution thanks to the combination of multiple images
- Greater efficiency thanks to optimum sensor-to-display adaptation
- Precise image fusion thanks to exact pixel positioning using APR
- Cost reduction through the use of low-cost cameras
APR technology at a glance:
- Registration image: Exact position detection of each pixel through targeted activation of individual areas
- Luminance test image: Measurement of luminance with high precision
- Stitching: Merge multiple images directly in display coordinates
