AUTOMATIC FOCUSING APPARATUS, PANEL DETECTION DEVICE AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/109466
Kind Code:
A1
Abstract:
An automatic focusing apparatus (200), a panel detection device, an automatic focusing method, and a panel detection method. The automatic focusing apparatus (200) comprises a distance measuring unit (210), an image acquisition unit (220), a driving unit (230), and a control unit (240) connected to the distance measuring unit (210) and the driving unit (230), wherein the driving unit (230) is connected to the image acquisition unit (220) and the distance measuring unit (210). The distance measuring unit (210) is configured to measure a distance between the image acquisition unit (220) and a target object, and when the distance is within a preset distance range, the distance measuring unit (210) sends a predetermined signal to the control unit (240), otherwise, the distance measuring unit (210) does not send the predetermined signal. The control unit (240) is configured to control the driving unit (230) on the basis of the predetermined signal to drive the image acquisition unit (220) and the distance measuring unit (210) to move together, so that the target object is imaged at the focus of the image acquisition unit (220). Therefore, blurred photographing of a region of interest of the target object caused by responding by the distance measuring unit (210) due to the impact of the presence of recesses, foreign matter and the like of the target object can be avoided. Hence, the imaging quality of a region of interest of the target object is ensured, and the imaging quality is remarkably improved.
