- edit: the example was outdated
Hey
first of all: Thank you very much kwagyeman. Great work. Very excited for the upcoming kickstarter!
However:
I am having some issues getting an example sketch running.
Example Sketch: find_numbers_1.py is giving me a hard time. The code looks like this:
# LetNet Example
import sensor, image, time
sensor.reset() # Reset and initialize the sensor.
sensor.set_contrast(3)
sensor.set_pixformat(sensor.GRAYSCALE) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.VGA) # Set frame size to QVGA (320x240)
sensor.set_windowing((128, 128)) # Set 128x128 window.
sensor.skip_frames(time = 2000) # Wait for settings take effect.
sensor.set_auto_gain(False)
sensor.set_auto_exposure(False)
while(True):
img = sensor.snapshot()
# NOTE: Uncomment to detect dark numbers on white background
# img.invert()
out = img.find_number(roi=(img.width()//2-14, img.height()//2-14, 28, 28))
img.draw_rectangle((img.width()//2-15, img.height()//2-15, 30, 30))
if out[1] > 5: # Confidence level
print("Number: %d Confidence: %0.2f" %(out[0], out[1]))
In this line:
out = img.find_number(roi=(img.width()//2-14, img.height()//2-14, 28, 28))
I am getting:
AttributeError: 'Image' object has no attribute 'find_number'
Setup:
- IDE: 2.0.0
- Cam: 3.0.0 [latest]
- OS: Windows 10 Pro, 64 Bit, Version: 1803, Build: 17134.228
Other examples are running fine. Am I missing a library? Or something else?
Thanks in advance,
Fabian
