Background:

Binocular camera calibration (BCC) is crucial for 3D reconstruction and depth perception.
Existing methods like Zhang's require multiple images and struggle with incomplete target visibility.
Efficient and robust BCC methods are needed for real-world applications.

Purpose of the Study:

To develop a precise and rapid binocular camera calibration method.
To overcome limitations of existing methods regarding image requirements and target completeness.
To enhance the accuracy and simplify the complexity of the calibration process.

Main Methods:

A novel stereo target with 12 coded planar targets, each corner uniquely numbered.
Utilizing a single calibration image per camera, even with incomplete target projection.
Implementing a multi-constraint optimization method to refine calibration accuracy.

Main Results:

The proposed method achieves accurate BCC with a single image, unlike traditional methods.
Significantly reduced reprojection errors and 3D measurement errors compared to Zhang's method.
Demonstrated robustness even with incomplete target projections.

Conclusions:

The proposed BCC method offers a precise, rapid, and simplified solution.
It outperforms existing methods in accuracy and efficiency, especially in challenging conditions.
The multi-constraint optimization further enhances the reliability of binocular camera systems.
