Zusammenfassung:The invention discloses a focusing method and device of camera equipment and a computer readable storage medium, and the method comprises the steps: carrying out the photographing of a target photographing scene, and obtaining a current photographing image; extracting chromaticity information and brightness information of the current shot image; performing low-frequency filtering processing on the brightness information to obtain low-frequency data; performing high-frequency filtering processing on the chromaticity information to obtain high-frequency data; generating a current focusing statistical value based on the low-frequency data and the high-frequency data; and adjusting the focal length of the camera device based on the current focusing statistical value. In this way, the focusing accuracy can be improved. 本申请公开了一种摄像设备的聚焦方法、装置和计算机可读存储介质,该方法包括:对目标拍摄场景进行拍摄,得到当前拍摄图像;提取当前拍摄图像的色度信息以及亮度信息;对亮度信息进行低频滤波处理,得到低频数据;对色度信息进行高频滤波处理,得到高频数据;基于低频数据与高频数据,生成当前聚焦统计值;基于当前聚焦统计值,调整摄像设备的焦距。通过上述方式,本申请能够提升聚焦的准确性。
