怎样将下边的识别并拍照的代码循环3此以上?
-
import sensor, image, time, pyb, time sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QQVGA) sensor.skip_frames(time = 2000) sensor.set_auto_gain(False) # must be turned off for color tracking sensor.set_auto_whitebal(False) # must be turned off for color tracking clock = time.clock() while(True): clock.tick() img = sensor.snapshot().lens_corr(1.8) for c in img.find_circles(threshold = 3500, x_margin = 10, y_margin = 10, r_margin = 10, r_min = 2, r_max = 100, r_step = 2): area = (c.x()-c.r(), c.y()-c.r(), 2*c.r(), 2*c.r()) #area为识别到的圆的区域,即圆的外接矩形框 statistics = img.get_statistics(roi=area) #像素颜色统计 print(statistics) #(0,100,0,120,0,120)是红色的阈值,所以当区域内的众数(也就是最多的颜色),范围在这个阈值内,就说明是红色的圆。 #l_mode(),a_mode(),b_mode()是L通道,A通道,B通道的众数。 if 0<statistics.l_mode()<100 and 0<statistics.a_mode()<127 and 0<statistics.b_mode()<127:#if the circle is red img.draw_circle(c.x(), c.y(), c.r(), color = (255, 0, 0)) #识别到的红色圆形用红色的圆框出来 else: img.draw_rectangle(area, color = (255, 255, 255)) #将非红色的圆用白色的矩形框出来 print("FPS %f" % clock.fps()) statistics=200 uart.write(str(kpts2)) #200回传到飞控 再n35模式里设置飞机悬停 也就是锁定xyz轴等待几秒运行下图拍照。 RED_LED_PIN = 1 BLUE_LED_PIN = 3 pyb.LED(RED_LED_PIN).on() sensor.skip_frames(time = 2000) # 给用户一个时间来准备 pyb.LED(RED_LED_PIN).off() pyb.LED(BLUE_LED_PIN).on() print("You're on camera!") img = sensor.snapshot() img.morph(1, [+2, +1, +0,\ +1, +1, -1,\ +0, -1, -2]) # 浮雕图像 img.save("1.jpg") # or "example.bmp" (or others) pyb.LED(BLUE_LED_PIN).off() print("Done! Reset the camera to see the saved image.") time.sleep_ms(1000) #延迟多久

没看懂你具体要做什么。哪个函数循环3次?
-
就是识别出形状和颜色然后拍照,然后回到识别形状和颜色在拍照。
-
for i in range(3)就行了
