The invention relates to the technical field of driving images, in particular to an eyebrow center positioning method for a transparent A-pillar. The invention provides an eyebrow center positioning method for a transparent A-pillar, which comprises the following steps of: S1, acquiring face 3D data; S2, detecting face key points; S3, calculating face posture data; S4, calculating a current coordinate of the eyebrow center; S5, judging whether the difference value between the current 2D coordinate of the eyebrow center and the 2D coordinate of the eyebrow center of the previous frame exceeds a preset range or not, if yes, determining that the eyebrow center moves normally, otherwise, determining that the 2D point jitters, and performing eyebrow center positioning correction; and S8, judging whether the difference value between the current coordinate of the eyebrow center and the coordinate of the eyebrow center in the last frame exceeds a threshold range or not, if yes, performing interpolation smoothing processing on the current coordinate of the eyebrow center, and putting an interpolation item into a cache. The anti-shake performance is improved, the user experience is improved, and the safety in the vehicle driving process is improved.

    本发明涉及行车影像技术领域,更具体的说,涉及一种用于透明A柱的眉心定位方法。本发明提供了用于透明A柱的眉心定位方法,包括:步骤S1、采集人脸3D数据;步骤S2、检测人脸关键点;步骤S3、计算人脸姿态数据;步骤S4、计算当前眉心坐标;步骤S5、判断当前眉心2D坐标与上一帧眉心2D坐标的差值是否超过预定范围,如果是,则认为是眉心正常移动,否则认为是2D点抖动,进行眉心定位校正;步骤S8、判断当前眉心坐标与上一帧眉心坐标的差值是否超过阈值范围,如果是,则对当前眉心坐标进行插值平滑处理,并将插值项放入缓存。本发明提升防抖性能,改善用户体验,提高车辆驾驶中的安全性。
