The invention provides an MR volume measurement method and device based on a 3D depth camera, and the method comprises the steps: calculating a view matrix according to a depth image information framewhen the depth image information frame containing a target object is obtained; calculating coordinates of each vertex of the target object under a camera coordinate system according to the depth image information frame; multiplying the coordinate of each vertex of the target object in the camera coordinate system by the inverse matrix of the view matrix to obtain the coordinate of each vertex ofthe target object in the world coordinate system; and calculating the volume of the target object by using the coordinates of each vertex of the target object in the world coordinate system. Accordingto the invention, volume measurement can be realized, and the precision of volume measurement can be improved. 本申请提供了一种基于3D深度摄像头的MR体积测量方法及装置，方法包括：在获取到包含有目标对象的深度图像信息帧时，依据深度图像信息帧，计算视图矩阵；依据深度图像信息帧，计算目标对象的各个顶点在相机坐标系下的坐标；分别将目标对象的各个
