SPECKLE PATTERN MATCHING METHOD, SPECKLE PATTERN MATCHING APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM

摘要

The present application relates to the field of three-dimensional image processing, and provided therein are a speckle pattern matching method, a speckle pattern matching apparatus, an electronic device, and a storage medium. The speckle pattern matching method in embodiments of the present application comprises: acquiring a test speckle pattern, the test speckle pattern comprising multiple speckle points; matching a first speckle point among the multiple speckle points with a corresponding speckle point in a calibration speckle pattern; if the matching is successful, then determining a pre-matching window by using the position of a first speckle point; comparing whether each speckle point in the pre-matching window of the test speckle pattern corresponds to the position of each speckle point in the pre-matching window of the calibration speckle pattern; when the number of successful pre-matching instances of a second speckle point in the test speckle pattern exceeds a first threshold, then determining that the second speckle point is successfully matched; and if each speckle point in the test speckle pattern is successfully matched with each corresponding speckle point in the calibration speckle pattern, then determining that the test speckle pattern is successfully matched. The overall number of matching instances is reduced and matching times are shortened.
