怎样提高拍照的清晰度

[laoguren1122]

如题，选择用模型匹配进行物体识别，发现分辨率不高，拍照模糊，怎样能提高呢

[laoguren1122]

@laoguren1122 程序如图
import time, sensor, image, math
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.

template = image.Image("/ball3.pgm")

low_threshold = (0, 50)
high_threshold = (195, 255)

clock = time.clock()

Run template matching

while (True):
clock.tick()
img = sensor.snapshot().lens_corr(1.8)

for x in range(4):

r = img.find_template(template, 0.70)
if r:
    img.draw_rectangle(r,color=0)

img.find_edges(image.EDGE_CANNY, threshold=(50, 80))

for c in img.find_circles(threshold = 2500, x_margin = 20, y_margin = 20, r_margin = 20):

img.draw_circle(c.x(), c.y(), c.r(), color = (0, 0, 0))

print(c)

print(clock.fps())
