摘　　要：数字切片扫描仪的扫描速度和图像质量是用户最为关注的两个指标。为了同时提高扫描速度和图像质量,设计了一种基于倾斜摄像头的实时对焦装置。该装置只需拍摄一张图像即可计算出离焦量,计算时间仅为12.1 ms,并在此基础上实现与扫描摄像头的同步工作,可以在连续扫描过程中实时跟踪焦面,即边扫描边对焦。与传统的先建模后扫描的方法相比,边扫描边对焦方法不仅省去了建模时间,同时提高了扫描质量。The scanning speed and image quality of the digital slide scanner are the two features that users are most concerned about.A real-time focusing configuration centered on a tilted camera is meant to enhance the scanning speed and image quality simultaneously.The device can calculate the defocus distance by taking only one image,and the computation time is only 12.1 ms.Furthermore,based on this,the focal plane can be tracked in real time during the continuous scanning by manipulating the tilted camera and the scanning camera synchronously,which is synchronous focusing and scanning.Synchronous focusing and scanning method saves modeling time and improve the image quality compared with the usual method of modeling first and scanning later.
