在Ubuntu上使用Python的turtle库,结合TensorFlow (TF) 的坐标变换,可以实现小海龟跟随特定路径或轨迹的跟随运动。以下是基本步骤:
1. 安装所需库:首先确保已经安装了Python、turtle和tensorflow等必要的库。如果还未安装,可以在终端运行:
```bash
pip install numpy tensorflow turtle
```
2. 导入所需的库:
```python
import turtle
import numpy as np
from tensorflow import math
```
3. 创建跟随函数:
```python
def follow_trajectory(trajectory_points, screen_width, screen_height):
# trajectory_points是一个包含x, y坐标的列表
screen = turtle.Screen()
screen.setup(width=screen_width, height=screen_height)
# 创建小海龟
turtle.penup()
turtle.goto(-screen_width / 2, -screen_height / 2)
turtle.pendown()
prev_point = None
for point in trajectory_points:
x, y = point
dx, dy = x - (prev_point[0] if prev_point else 0), y - (prev_point[1] if prev_point else 0)
# 使用TF计算新位置,这里简单地将比例映射到屏幕范围内
new_x = int(screen_width * dx / max(abs(dx), abs(dy)))
new_y = int(screen_height * dy / max(abs(dx), abs(dy)))
turtle.goto(new_x, new_y)
prev_point = point
# 结束绘制并保持窗口打开
turtle.done()
# 示例路径数据
trajectory_points = [(0, 0), (50, 0), (75, 50), (50, 100)]
follow_trajectory(trajectory_points, 640, 480)
```
