Meanwhile, the problem of ultrasound images capturing and position information of Bird collecting synchronously are solved by the technique of callback mechanism in VFW SDK, which establishes good foundation for the 3D reconstruction.

• 同时，本文利用了VFW视频开发的回调机制技术，成功地解决了超声图像与Bird位置数据的同步采集问题,为后续的三维重建奠定了良好的基础。
