相机标定代码
当然,这是完全可以的!下面是一个简单的相机标定Python代码示例,使用OpenCV库:
```python
import cv2
import numpy as np
# 读入标定板图像
chessboard = cv2.imread('chessboard.png')
# 定义标定板格子大小
square_size = 0.025 # 25mm
# 定义标定板角点数量
pattern_size = (9, 6)
# 获取标定板角点
ret, corners = cv2.findChessboardCorners(chessboard, pattern_size)
if ret:
# 定义物体点(即标定板上的角点)和图像点的数组
objpoints = []
imgpoints = []
# 将标定板的物体点添加到objpoints中
objp = np.zeros((pattern_size[0] * pattern_size[1], 3), np.float32)
objp[:, :2] = np.mgrid[0:pattern_size[0],0:pattern_size[1]].T.reshape(-1, 2) * square_size
for i in range(len(corners)):
objpoints.append(objp)
# 将标定板的图像点添加到imgpoints中
imgpoints.append(corners)
# 进行摄像头标定
ret, mtx, dist, rvecs, tvecs = cv2.calibrateCamera(objpoints, imgpoints, chessboard.shape[:-1], None, None)
# 打印结果
print("相机矩阵:\n", mtx)
print("畸变系数:\n", dist)
else:
print("无法检测到标定板角点。")
```
这段代码将返回相机矩阵和畸变系数,用于校正摄像头图像。
