Autostereoscopic Display Calibration via Camera Position Detection

The patent applies preliminary action by pre-defining a standard mounting position and orientation for the imaging array on the display device. The calibration method establishes reference positions before the imaging array is mounted, and the user is guided to align the imaging array with these pre-established references, ensuring consistent alignment without requiring complex real-time adjustment mechanisms.

The patent replaces complex mechanical alignment systems with an automated optical calibration system. Instead of using精密 mechanical positioning structures that would be required to maintain alignment precision through repeated mounting and detaching, the system uses a camera to capture images and software algorithms to automatically calculate and adjust alignment parameters, substituting mechanical precision requirements with computational correction.

The patent applies self-service by enabling the calibration system to automatically perform alignment verification and parameter adjustment without requiring external dedicated alignment equipment or trained personnel. The camera captures images of the display and imaging array, and the embedded software automatically processes these images to determine alignment status and generate correction parameters, making the system self-calibrating.

The patent applies universality by designing a calibration system that uses standard components (camera, display, processor) already present in the device, rather than requiring specialized dedicated alignment equipment. The same camera used for normal operation can be utilized for calibration purposes, and the software runs on the existing processor, making the calibration functionality universal and integrated into the device's existing architecture.

The patent applies feedback by using the camera to capture images during calibration and then processing these images to determine the actual camera position and orientation. The system provides feedback information about the detected position, and based on this feedback, automatically calculates correction parameters to compensate for any positioning deviations, allowing calibration to proceed successfully even with less strict positioning requirements.

The patent applies parameter changes by dynamically adjusting calibration parameters based on the detected camera position. Instead of requiring the camera to be positioned at a fixed predetermined location, the system detects the actual camera position parameters from the captured images and modifies the calibration calculations accordingly, allowing flexibility in camera placement while maintaining calibration accuracy through parameter adaptation.
