好的,以下是一个简单的手眼标定代码,使用Python编写,需要使用OpenCV和numpy库:
```python
import numpy as np
import cv2
# 手眼标定函数
def hand_eye_calibration(hand_poses, object_poses):
num_poses = len(hand_poses)
A = np.zeros((3*num_poses, 3))
B = np.zeros((3*num_poses, 1))
for i in range(num_poses):
R_h = hand_poses[i][:3, :3]
t_h = hand_poses[i][:3, 3]
R_o = object_poses[i][:3, :3]
t_o = object_poses[i][:3, 3]
A[3*i:3*(i+1), :] = np.eye(3) - R_h.dot(R_o.T)
B[3*i:3*(i+1), :] = t_h.reshape(-1, 1) - R_h.dot(t_o.reshape(-1, 1))
x = np.linalg.inv(A.T.dot(A)).dot(A.T).dot(B)
return x.flatten()
# 主函数
if __name__ == '__main__':
# 手臂姿态数据
hand_poses = []
# 物体姿态数据
object_poses = []
# 读取手臂姿态数据和物体姿态数据
for i in range(10):
hand_pose_file = 'hand_pose_{}.txt'.format(i)
object_pose_file = 'object_pose_{}.txt'.format(i)
hand_pose = np.loadtxt(hand_pose_file)
object_pose = np.loadtxt(object_pose_file)
hand_poses.append(hand_pose)
object_poses.append(object_pose)
# 手眼标定
x = hand_eye_calibration(hand_poses, object_poses)
print(x)
```
在上述代码中,我们定义了一个`hand_eye_calibration`函数用于手眼标定,该函数接收手臂姿态数据和物体姿态数据作为输入,返回标定结果。主函数中,我们通过读取手臂姿态数据和物体姿态数据,然后调用`hand_eye_calibration`函数进行标定,最后输出标定结果。
需要注意的是,上述代码只是一个简单的示例,实际应用中需要根据具体情况进行修改和优化。
