如何将识别的坐标,逐个输出?
-
如识别圆,将c.x的值单独赋给一个变量

打印c.x()
import sensor, image, time sensor.reset() sensor.set_pixformat(sensor.RGB565) # 灰度更快 sensor.set_framesize(sensor.QQVGA) sensor.skip_frames(time = 2000) clock = time.clock() while(True): clock.tick() #lens_corr(1.8)畸变矫正 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): img.draw_circle(c.x(), c.y(), c.r(), color = (255, 0, 0)) print(c.x())
赋值c.x():
变量在哪里都可以,例子是全局变量。import sensor, image, time sensor.reset() sensor.set_pixformat(sensor.RGB565) # 灰度更快 sensor.set_framesize(sensor.QQVGA) sensor.skip_frames(time = 2000) clock = time.clock() 圆 = 0 while(True): clock.tick() #lens_corr(1.8)畸变矫正 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): img.draw_circle(c.x(), c.y(), c.r(), color = (255, 0, 0)) 圆 =c.x() print(圆)

我的意思是将c.x内的坐标分别赋值给不同的变量,将x1,x2,x3等等单独列出来
-
circles = img.find_circles(xxx)
circles
就是一个数组circles[0].x()
就是第一个圆的中心x。circles[1].x()
就是第二个圆的中心x。circles[2].x()
就是第三个圆的中心x。
