Division by Zero #2

Closed ryanlelek closed 9 years ago

ryanlelek commented 10 years ago

I'm receiving a "ZeroDivisionError: float division by zero" exception. This is confirmed to be initiated from line 43 of cv_utils.py.

python_card_scan_division_by_zero

# Original Line 43
return cv.DotProduct(tmp1, tmp2) /  (cv.Sum(norm1)[0]*cv.Sum(norm2)[0])**0.5

# Edited - Prevents Crash (may affect card recognition)
return cv.DotProduct(tmp1, tmp2) /  (((cv.Sum(norm1)[0]*cv.Sum(norm2)[0])**0.5) + 0.1)

Will continue debugging (been at it for about 8 hours trying to get one card to recognize).

OS: Clean Lubuntu 12.10 Using Python v2.7.2 (Python 3.x throws a syntax error)

Made progress and things are working on another machine. Going to test further to see what the issue was. Will update with more info soon
