ルーチン説明-03-arrow_drawing矢印を描く
このルーチンは 03-Drawing-arrow_drawing.py です。
# 绘制箭头
#
# 这个例子展示了如何使用OpenMV内置的画箭头功能。
import sensor
import time
from random import randint
sensor.reset()
sensor.set_pixformat(sensor.RGB565) # or GRAYSCALE...
sensor.set_framesize(sensor.QVGA) # or QQVGA...
sensor.skip_frames(time=2000)
clock = time.clock()
while True:
clock.tick()
img = sensor.snapshot()
for i in range(10):
x0 = randint(0, 2 * img.width()) - img.width() // 2
y0 = randint(0, 2 * img.height()) - img.height() // 2
x1 = randint(0, 2 * img.width()) - img.width() // 2
y1 = randint(0, 2 * img.height()) - img.height() // 2
r = randint(0, 127) + 128
g = randint(0, 127) + 128
b = randint(0, 127) + 128
# # If the first argument is a scaler then this method expects
# to see x0, y0, x1, and y1. Otherwise, it expects a (x0,y0,x1,y1) tuple.
# 如果第一个参数是scaler,那么此方法应传递x0、y0、x1和y1。否则,它期望有一个(x0,y0,x1,y1)元组
img.draw_arrow(x0, y0, x1, y1, color=(r, g, b), size=30, thickness=2)
print(clock.fps())
つまり、好きなように矢印を描くだけです...
