A vehicle coordinate system reconstruction method for end of line calibration applications.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Sensor calibration is a crucial step to ensure the proper functioning of advanced driver assistance systems (ADAS), and vehicle coordinate system reconstruction is an indispensable part of this process. However, the currently mainstream vehicle alignment platforms are characterized by high costs, complex structures, and immobility, making them unsuitable for the rapid upgrade and transformation pace of modern automotive manufacturers. To address these limitations, this paper proposes a low-cost, flexible solution based on extracting key feature points from the car body-in-white. First, the paper introduces the reconstruction principles based on rigid body transformation. Then, the method for selecting the necessary feature points and its general applicability are discussed. Third, the paper describes how to mitigate the influence of vehicle body color by choosing appropriate light sources, and it employs suitable algorithms to complete the feature point extraction process. Finally, validation experiments were designed to verify the accuracy of the proposed method, demonstrating that it achieves better reconstruction precision compared to the vehicle alignment platforms.
