hi
Please help me Connect LCD to Face_Detection .
please Source code
Hi, you just need to add the following to the face detection example:
import lcd
lcd.init() # Initialize the lcd screen. (before loop)
And send images to LCD:
lcd.display(img) # display the image.
Full script:
import sensor, time, image, lcd
# Reset sensor
sensor.reset()
# Sensor settings
sensor.set_contrast(1)
sensor.set_gainceiling(16)
# HQVGA and GRAYSCALE are the best for face tracking.
sensor.set_framesize(sensor.HQVGA)
sensor.set_pixformat(sensor.GRAYSCALE)
lcd.init()
# Load Haar Cascade
# By default this will use all stages, lower satges is faster but less accurate.
face_cascade = image.HaarCascade("frontalface", stages=25)
print(face_cascade)
# FPS clock
clock = time.clock()
while (True):
clock.tick()
# Capture snapshot
img = sensor.snapshot()
# Find objects.
# Note: Lower scale factor scales-down the image more and detects smaller objects.
# Higher threshold results in a higher detection rate, with more false positives.
objects = img.find_features(face_cascade, threshold=0.75, scale_factor=1.25)
# Draw objects
for r in objects:
img.draw_rectangle(r)
lcd.display(img)
# print FPS
print(clock.fps())
Thank you very much.
