很高兴为您提供帮助!以下是基于栅格地图的双向LSTM的路径规划代码,包括输出路径的图像。
首先,我们需要导入所需的库和模块:
``` python
import numpy as np
import tensorflow as tf
import matplotlib.pyplot as plt
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import LSTM, Bidirectional, Dense
```
接下来,我们将定义模型的参数和数据:
``` python
# 模型参数
input_shape = (100, 100, 1)
output_shape = (100, 100, 1)
hidden_units = 128
num_layers = 2
dropout_rate = 0.2
# 数据
x_train = np.random.rand(1000, 100, 100, 1)
y_train = np.random.rand(1000, 100, 100, 1)
```
接下来,我们将构建模型:
``` python
model = Sequential()
# 双向LSTM层
for i in range(num_layers):
if i == 0:
model.add(Bidirectional(LSTM(hidden_units, return_sequences=True), input_shape=input_shape))
else:
model.add(Bidirectional(LSTM(hidden_units, return_sequences=True)))
model.add(tf.keras.layers.Dropout(dropout_rate))
# 输出层
model.add(Dense(output_shape[-1], activation='softmax'))
# 编译模型
model.compile(optimizer='adam', loss='mse', metrics=['accuracy'])
```
然后,我们将训练模型:
``` python
history = model.fit(x_train, y_train, epochs=10, batch_size=32, validation_split=0.2)
```
最后,我们将输出路径的图像:
``` python
# 取出一个测试样本
x_test = np.random.rand(1, 100, 100, 1)
y_test = model.predict(x_test)
# 绘制原始地图
plt.imshow(x_test[0,:,:,0], cmap='gray')
plt.title('Original Map')
plt.show()
# 绘制路径规划结果
plt.imshow(y_test[0,:,:,0], cmap='gray')
plt.title('Path Planning Result')
plt.show()
```
这样,我们就可以生成基于栅格地图的双向LSTM的路径规划代码,并输出路径的图像。
