A method to scan the QR code in the dark avoiding reflection of flashlight by mosaicing

Background: Nowadays, two-dimensional code is widely used, it provide us great convenience in daily life. For example, we use two-dimensional code to pay, to help social communicate and so on. Even ride the shared bicycles, we can use two-dimensional code to unlock the lock. And the same time, the equipment is developed more and more simple, now the camera in our mobile phone can scan the two-dimensional code. However, there is fatal drawback when we use two-dimensional code. When we scan the two-dimensional code in dark, we need to open the light of camera. The light will be reflected by the plastic of the two-dimensional code, which makes the camera can hardly identify the two-dimensional code. The following two pictures is the example.

Invention Description – Summary This disclosure proposes a method to identify QR code by camera of mobile phones in dark environment of which flash reflection effect can be eliminated. We cut the QR code into sub pictures and calculate the reflection effect extent of every sub picture. Sub pictures which are more effected by reflection will be replaced by less ones cut from pictures taken from other shooting angle.

Claim points:

(1) A method of synthesis more than one pictures of multi-angle to eliminate the reflection impact when readers identify a two-dimensional code.

Advantage:

This invention provides way of synthesis more than one pictures of multi-angle to help identify the two-dimensional code in the case of reflection.

(1)This method makes two-dimensional code identification on reflection condition easier.

(2)This method can be implemented easily and takes quite low cost. Our method only need change the identifying two-dimensional code software, this method is simple and low cost.

(3)All the two-dimensional code scan...
