结合附图,对于系统中的各个部件进行具体说明。Each component in the system will be described in detail with reference to the accompanying drawings.
对于手环遥控装置1,内嵌单片机、惯性测量单元(IMU)及Zigbee模块(如图7)。其中IMU中内置有三轴陀螺仪与加速度计、磁力计,可根据内部集成的捷联惯导算法提供与手环相固连的坐标系相对于东北天坐标系位姿,经坐标转换标定后可得到手环坐标系相对于全局坐标系的三维位置(x,y,z)及欧拉角(α,β,γ);单片机接收到手环坐标系位姿信息后将其通过串口协议发送给Zigbee模块,Zigbee模块再通过Zigbee通信协议以无线传输的方式将手环坐标系位姿信息实时发送给控制中心4。For the bracelet
在调整无影灯位置和角度的过程中,术者食指指向需要被照亮的位置Pf,无影灯就会将光线对准Pf,随后,术者通过小臂转动调整手环姿态,从而控制无影灯的照射角度。无影灯系统根据手环坐标系位姿信息(三维坐标和欧拉角)来计算照射位置Pf和照射方向,具体计算方法如下,计算方法如下,计算方法中涉及到的坐标、角度、向量、旋转矩阵皆相对于一个统一的全局坐标系,各坐标系(手环坐标系、外部摄像头坐标系、无影灯坐标系、东北天坐标系)皆经过标定而被统一:In the process of adjusting the position and angle of the shadowless lamp, the operator's index finger points to the position P f that needs to be illuminated, and the shadowless lamp will align the light at P f . Then, the operator adjusts the posture of the bracelet by turning the forearm to control the shadowless lamp. Irradiation angle. The shadowless lamp system calculates the irradiation position P f and the irradiation direction according to the pose information of the wristband coordinate system (three-dimensional coordinates and Euler angle). The specific calculation method is as follows. The calculation method is as follows. The coordinates, angles, vectors, and rotations involved in the calculation method The matrices are all relative to a unified global coordinate system, and each coordinate system (bracelet coordinate system, external camera coordinate system, shadowless lamp coordinate system, northeast sky coordinate system) is calibrated and unified:
照射位置Pf的计算:考虑到手环坐标系的原点Pwrist(如图8)与示指方向起点(即掌指关节)Phand不重合,且示指方向与手环坐标系X轴存在一定夹角,需通过如图8所示的几何尺寸进行相应补偿,从而获得更加精确的示指方向及示指方向起点位置。首先,根据欧拉角计算出手环坐标系对应的旋转矩阵为:Calculation of the irradiation position P f : Considering that the origin P wrist of the wristband coordinate system (as shown in Figure 8) does not coincide with the starting point of the index finger direction (ie, the metacarpophalangeal joint) P hand , and there is a certain angle between the index finger direction and the X axis of the wristband coordinate system , it is necessary to make corresponding compensation through the geometric dimensions as shown in Figure 8, so as to obtain a more accurate indexing direction and the starting point position of the indexing direction. First, calculate the rotation matrix corresponding to the wristband coordinate system according to the Euler angle:
其中,旋转矩阵R的第一列即为手环坐标系的X轴对应的单位向量:Among them, the first column of the rotation matrix R is the unit vector corresponding to the X-axis of the bracelet coordinate system:
旋转矩阵R的第三列为手环坐标系的Z轴对应的单位向量:The third column of the rotation matrix R is the unit vector corresponding to the Z axis of the bracelet coordinate system:
示指方向与无影灯坐标系X轴方向夹角θ1、手环坐标系原点Pwrist与示指指节点Phand之间的距离偏差d1与d2均为可以术前设定的补偿量,可设置其默认值分别为30°、3mm、12mm。根据图示,手环坐标系X轴与示指方向夹角为θ1,可计算出示指方向单位向量为:The included angle θ 1 between the direction of the index finger and the X-axis direction of the shadowless lamp coordinate system, and the distance deviation d1 and d2 between the origin of the bracelet coordinate system P wrist and the node P hand of the index finger are all compensations that can be set before surgery, and the default can be set The values are 30°, 3mm, 12mm respectively. According to the diagram, the angle between the X-axis of the wristband coordinate system and the direction of the index finger is θ 1 , and the unit vector of the direction of the index finger can be calculated as:
示指方向起点Phand坐标为:The coordinates of the starting point P hand in the direction of the index finger are:
可根据示指方向起点Phand、示指方向对应的单位向量手术台平面高度h1计算出术者食指指向的照射点Pf的三维坐标:According to the starting point P hand of the indexing direction and the unit vector corresponding to the indexing direction Calculate the three-dimensional coordinates of the irradiation point P f pointed by the operator's index finger from the plane height h 1 of the operating table:
照射方向及无影灯目标位姿的计算:参照图9,无影灯系统通过伺服电机与连杆调整无影灯灯面的角度,使得照射方向的俯仰角及偏航角与示指方向的俯仰角与偏航角保持一致,照射方向的俯仰角φ,与偏航角θ如图9所示。C是术者的几何中心,由外置深度视觉摄像头5通过YOLO算法给出,A是无影灯的几何中心在水平面上的投影,计算俯仰角时,以水平面为基准面,照射方向B-Pf与水平面上的Pf-A所成夹角即为俯仰角φ,计算偏航角时,以术者所在竖直面作为基准面,无影灯所在竖直平面Pf-A-D与术者几何中心所在竖直平面Pf-C-D-E所成夹角为照射方向的偏航角θ。术者通过手环来控制无影灯照射的角度,照射方向的俯仰角及偏航角始终与修正过后的示指方向的俯仰角及偏航角保持一致。无影灯系统根据照射点坐标Pf、照射方向俯仰角φ及偏航角θ、以及无影灯高度的设定值h来计算无影灯处于的位置和姿态。Calculation of the irradiation direction and the target pose of the shadowless lamp: Referring to Figure 9, the shadowless lamp system adjusts the angle of the lamp surface of the shadowless lamp through the servo motor and the connecting rod, so that the pitch angle and yaw angle of the irradiation direction are the same as the indexing direction The pitch angle and the yaw angle are consistent, and the pitch angle φ and yaw angle θ of the irradiation direction are shown in Figure 9. C is the geometric center of the operator, which is given by the external
无影灯目标位置的三维坐标如下式:The three-dimensional coordinates of the target position of the shadowless lamp are as follows:
同时,无影灯需要调整角度使得无影灯灯面与照射方向垂直。At the same time, the shadowless lamp needs to adjust the angle so that the surface of the shadowless lamp is perpendicular to the irradiation direction.
无影灯系统根据无影灯目标位姿,以及术者及周围术者的位置(通过外部摄像头获得)来规划移动轨迹,考虑到术者在无影灯的位姿调节过程中可能会发生移动,系统采用人工势场法进行实时路径规划以避免无影灯与术者可能产生的碰撞。人工势场法在无影灯目标位置附近产生引力场,并将术者及周围术者当作障碍物,在其周围产生斥力场,使得无影灯能够快速向目标位置靠拢,同时又避开障碍物,具体算法公式如下:The shadowless lamp system plans the movement trajectory according to the target pose of the shadowless lamp, as well as the position of the operator and surrounding operators (obtained through an external camera). Considering that the operator may move during the adjustment of the pose of the shadowless lamp, the system uses an artificial potential field Real-time path planning can be performed to avoid possible collisions between the shadowless lamp and the operator. The artificial potential field method generates a gravitational field near the target position of the shadowless lamp, and regards the operator and surrounding operators as obstacles, and generates a repulsive field around it, so that the shadowless lamp can quickly approach the target position while avoiding obstacles. The algorithm formula is as follows:
其中,Uatt是无影灯目标位置所产生的引力场势能,Urep是第i个术者所产生的斥力场势能,B是无影灯当前位置的三维坐标,Bgoal是无影灯的目标位置,Pi是第i个术者几何中心的三维坐标,||B-Bgoal||表示无影灯距离其目标位置的距离,ε和η均为势场比例因子,dgoal与drep分别是引力场与斥力场影响范围阈值。无影灯在引力场和斥力场的同时影响下朝向其目标位置移动,过程中能够避开与术者的碰撞,无影灯的速度的计算公式如下:Among them, U att is the potential energy of the gravitational field generated by the target position of the shadowless lamp, U rep is the potential energy of the repulsive field generated by the i-th operator, B is the three-dimensional coordinates of the current position of the shadowless lamp, B goal is the target position of the shadowless lamp, and Pi is The three-dimensional coordinates of the i-th operator's geometric center, ||BB goal || indicates the distance between the shadowless lamp and its target position, ε and η are potential field scaling factors, d goal and d rep are the influence ranges of the gravitational field and the repulsive field respectively threshold. The shadowless lamp moves towards its target position under the influence of the gravitational field and the repulsive field at the same time, and can avoid collision with the operator during the process. The calculation formula of the shadowless lamp's speed is as follows:
其中,是实时规划的无影灯的速度,U是无影灯当前位置的引力与斥力的合势场,是势场在无影灯当前位置的梯度。随后,控制中心4将无影灯移动速度通过雅克比矩阵J和机器人逆向运动学公式转换为无影灯连杆驱动机构的伺服电机的轴旋转速度,并发送给无影灯灯架3,将无影灯从当前位置移动到目标位置。in, is the speed of the shadowless lamp planned in real time, U is the resultant potential field of the gravitational and repulsive forces at the current position of the shadowless lamp, is the gradient of the potential field at the current position of the shadowless lamp. Subsequently, the
