模板识别和颜色识别能串起来一起用吗

惠斯

另外想问一下，模板识别想识别0到9，但是它会报错，说是请降低像素，减少在运行的数量，降低像素还是不能解决。最后减少了3个数字它才能正常的运行，这怎么解决？

请发具体的代码，与报错提示。

import time, sensor, image
from image import SEARCH_EX, SEARCH_DS

Reset sensor

sensor.reset()

Set sensor settings

sensor.set_contrast(1)
sensor.set_gainceiling(16)

Max resolution for template matching with SEARCH_EX is QQVGA

sensor.set_framesize(sensor.QQVGA)

You can set windowing to reduce the search image.

#sensor.set_windowing(((640-80)//2, (480-60)//2, 80, 60))
sensor.set_pixformat(sensor.GRAYSCALE)

Load template.

Template should be a small (eg. 32x32 pixels) grayscale image.

template0 = image.Image("/0.pgm")
template1 = image.Image("/1.pgm")
template2 = image.Image("/2.pgm")
template3 = image.Image("/3.pgm")
template4 = image.Image("/4.pgm")
template5 = image.Image("/5.pgm")
template6 = image.Image("/6.pgm")
template7 = image.Image("/7.pgm")
template8 = image.Image("/8.pgm")
template9 = image.Image("/9.pgm")

clock = time.clock()

Run template matching

while (True):
clock.tick()
img = sensor.snapshot()

# find_template(template, threshold, [roi, step, search])
# ROI: The region of interest tuple (x, y, w, h).
# Step: The loop step used (y+=step, x+=step) use a bigger step to make it faster.
# Search is either image.SEARCH_EX for exhaustive search or image.SEARCH_DS for diamond search
#
# Note1: ROI has to be smaller than the image and bigger than the template.
# Note2: In diamond search, step and ROI are both ignored.
r0 = img.find_template(0, 0.70, step=4, search=SEARCH_EX)
if r0:
    print('0')
r1 = img.find_template(1, 0.70, step=4, search=SEARCH_EX) 
if r1:
    print('1')
r2 = img.find_template(2, 0.70, step=4, search=SEARCH_EX)
if r2:
    print('2')
r3 = img.find_template(3, 0.70, step=4, search=SEARCH_EX) 
if r3:
    print('3')
r4 = img.find_template(4, 0.70, step=4, search=SEARCH_EX)
if r4:
    print('4')
r5 = img.find_template(5, 0.70, step=4, search=SEARCH_EX) 
if r5:
    print('5')
r6 = img.find_template(6, 0.70, step=4, search=SEARCH_EX)
if r6:
    print('6')
r7 = img.find_template(7, 0.70, step=4, search=SEARCH_EX) 
if r7:
    print('7')
r8 = img.find_template(8, 0.70, step=4, search=SEARCH_EX) 
if r8:
    print('8')
r9 = img.find_template(9, 0.70, step=4, search=SEARCH_EX) 
if r9:
    print('9')
