如何从生物识别设备连续捕获指纹 [英] How to capture fingerprint continuously from biometric device

问题描述

在生物识别SDK中，我仅具有捕获单个图像的功能.但是我需要连续捕获图像.

In biometric sdk I have only functions to capture single image. But I need to capture images continuously. Would you please help me?

推荐答案

s_akram，

您将需要设置一个循环以重复从SDK中采样图像.

为了避免阻塞UI(或其他应用程序进程)，您需要将其放在其他线程上.这是使用简单但友好的BackgroundWorker的文章:
BackgroundWorker线程和支持取消功能 [

s_akram,

You will need to set up a loop to repeatedly sample the image from the SDK.

So that you don''t block the UI (or other application processes) you''ll want to put that on a different thread. Here''s an article using the simple, but friendly, BackgroundWorker:
