Hello,
we Need help with our Programm to detect Barcodes.
Can someone help us please?
Here is the code and a Screenshot with the Error:
from __future__ import print_function
import pixy
from ctypes import *
from pixy import *
# pixy2 Python SWIG get line features example #
print("Pixy2 Python SWIG Example -- Get Line Features")
pixy.init ()
pixy.change_prog ("line")
class Vector (Structure):
_fields_ = [
("m_x0", c_uint),
("m_y0", c_uint),
("m_x1", c_uint),
("m_y1", c_uint),
("m_index", c_uint),
("m_flags", c_uint) ]
class IntersectionLine (Structure):
_fields_ = [
("m_index", c_uint),
("m_reserved", c_uint),
("m_angle", c_uint) ]
class Barcode (Structure):
_fields_ = [
("m_x", c_uint),
("m_y", c_uint),
("m_flags", c_uint),
("m_code", c_uint) ]
vectors = VectorArray(100)
intersections = IntersectionLineArray(100)
barcodes = BarcodeArray(100)
frame = 0
while 1:
line_get_all_features ()
i_count = line_get_intersections (100, intersections)
v_count = line_get_vectors (100, vectors)
b_count = line_get_barcodes (100, barcodes)
if i_count > 0 or v_count > 0:
print('frame %3d:' % (frame))
frame = frame + 1
for index in range (0, i_count):
print('[INTERSECTION: INDEX=%d ANGLE=%d]' % (intersections[index].m_index, intersections[index].m_angle))
for index in range (0, v_count):
print('[VECTOR: INDEX=%d X0=%3d Y0=%3d X1=%3d Y1=%3d]' % (vectors[index].m_index, vectors[index].m_x0, vectors[index].m_y0, vectors[index].m_x1, vectors[index].m_y1))
for index in range (0, b_count):
print('[BARCODES: INDEX=%d x=%d Y0=%3d X1=%3d]' % (barcodes[index].m_x, barcodes[index].m_y, barcodes[index].m_flags, barcodes[index].m_code))
