RE: 颜色过去以后会出现好几遍这个颜色,能不能只出现一次
现在是会出现好几个1好几个2好几个4但是我只想要一个124,就是这个红色会识别很多次绿色会识别很多次,蓝色会识别很多次

两个程序运行
我要识别三个颜色,当三个颜色识别结束以后退出颜色识别程序打开二维码扫码程序,但是不能累加颜色识别计数
这是程序import sensor, image,time,pyb,utime import sensor, image, time,utime from pyb import UART p0 = pyb.Pin('P0', pyb.Pin.OUT_PP) p0.value(1) uart = UART(3, 57600) output_str=0 yanse=0 flag0=1 f=0 while 1: if uart.any(): flag0=uart.readline().decode() flag0=int(flag0) print(flag0) if flag0==1: thresholds= [(60, 18, 37, 75, -35, 76),(58, 24, -11, 17, -61, -16),(60, 30, -17, -58, -43, 31)] sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QVGA) sensor.skip_frames(time = 2000) sensor.set_auto_gain(False) sensor.set_auto_whitebal(False) while flag0 : img = sensor.snapshot() blobs=img.find_blobs(thresholds, pixels_threshold=5000, area_threshold=400) for blob in blobs: img.draw_rectangle(blob.rect()) img.draw_cross(blob.cx(), blob.cy()) yanse="%s" % (blob.code()) print( yanse) pyb.delay(500) if yanse : f=f+1 uart.write(yanse) yanse=0 if f==3 : flag0=2 if flag0==2: sensor.reset() sensor.set_pixformat(sensor.GRAYSCALE) sensor.set_framesize(sensor.VGA) sensor.set_windowing((240, 240)) sensor.skip_frames(30) sensor.set_auto_gain(False) while flag : img = sensor.snapshot() img.lens_corr(0.1) for code in img.find_qrcodes(): img.draw_rectangle(code.rect(), color = (255, 0, 0)) output_str="%s" % (code.payload()) print(output_str) pyb.delay(500) if output_str: uart.write(output_str) pyb.delay(10) p0.value(0) pyb.delay(10) p0.value(1) output_str=0 flag=0
