抱歉,之前的代码中确实缺少了`pattern_size`的定义。请将`pattern_size`替换为`pattern`,因为在之前的代码中,`pattern`变量用于存储角点数目。
以下是修改后的代码:
```python
import numpy as np
import cv2
# 准备标定板参数
pattern = (9, 6) # 部角点数目
square_size = 25 # 每个棋盘格的边长(单位:毫米)
# 准备用于标定的图像路径(替换实际的图像路径)
image_paths = [
'path_to_image1.jpg',
'path_to_image2.jpg',
'path_to_image3.jpg',
...
]
# 创建存储角点和物体点的列表
obj_points = [] # 真实世界坐标点
img_points = [] # 图像平面角点
# 准备物体坐标
objp = np.zeros((pattern[0] * pattern[1], 3), np.float32)
objp[:, :2] = np.mgrid[0:pattern[0], 0:pattern[1]].T.reshape(-1, 2) * square_size
for image_path in image_paths:
# 读取图像
img = cv2.imread(image_path)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
# 查找角点
ret, corners = cv2.findChessboardCorners(gray, pattern, None)
if ret:
obj_points.append(objp)
img_points.append(corners)
# 进行相机标定
ret, mtx, dist, rvecs, tvecs = cv2.calibrateCamera(obj_points, img_points, gray.shape[::-1], None, None)
# 打印相机内参和畸变参数
print("相机内参 (Camera Matrix):\n", mtx)
print("\n畸变系数 (Distortion Coefficients):\n", dist)
# 保存相机参数
np.save("camera_matrix.npy", mtx)
np.save("dist_coeffs.npy", dist)
```
请确保替换`image_paths`为实际的图像路径,并且安装了OpenCV库。运行时,它将输出相机内参和畸变系数,并将这些参数保存到`camera_matrix.npy`和`dist_coeffs.npy`文件中。
