示例1: _detect_qrcode_frame
# 需要导入模块: from kivy.uix.image import Image [as 别名]
# 或者: from kivy.uix.image.Image import getSymbols [as 别名]
def _detect_qrcode_frame(self, instance, camera, data):
global data_qr
# the image we got by default from a camera is using the NV21 format
# zbar only allow Y800/GREY image, so we first need to convert,
# then start the detection on the image
parameters = camera.getParameters()
size = parameters.getPreviewSize()
barcode = Image(size.width, size.height, 'NV21')
barcode.setData(data)
barcode = barcode.convert('Y800')
result = self._scanner.scanImage(barcode)
if result == 0:
self.symbols = []
return
# we detected qrcode! extract and dispatch them
symbols = []
it = barcode.getSymbols().iterator()
while it.hasNext():
symbol = it.next()
qrcode = BtmsValidRoot.Qrcode(
