Augmented reality simulation of cardiovascular interventional surgery Mar 2020- May 2021. - Implemented the framework of surgery training assistant system based on augmented reality. - Predicted the operation trajectory using LSTM and use kdtree to calculate the distance for operation safety warning. - Displayed the vascular model in augmented reality with OpenGL, and design UI interface to adjust the size, rotation and translation of the model. - The marker of aruco Library in OpenCV is used to realize the coordinate positioning of QR code.
