Abstract
Disclosed is a method and device for regulating imaging accuracy of a motion-sensing camera. The method comprises: acquiring an infrared speckle pattern in a target infrared scene; recognizing an actual definition, an actual speckle regularity, and an actual central region brightness of the infrared speckle pattern; comparing the actual definition with a preset definition, the actual speckle regularity with a preset speckle regularity, and the actual central region brightness with a preset brightness; and adjusting an imaging focal length according to a comparison result, and completing regulation of the imaging accuracy. In this way, the method for regulating imaging accuracy of a motion-sensing camera of the present invention can obtain an infrared speckle pattern having required imaging accuracy. Thus, the quality of a depth map formed by conversion from the infrared speckle pattern can be highly improved, which provides a high-quality data source for subsequent skeleton-based recognition and gesture recognition.
