Embodiment 1
[0026] like figure 1 As shown, a scanning device with a dual-channel dual-focus sensor includes an image processing module 3, an image definition calculation and judgment module 4, a scanning recognition module 5, a No. 1 image sensor 1 with a short focal length, and a No. 2 image sensor with a far focal length. 2. No. 1 image sensor 1, image processing module 3, image resolution calculation and judgment module 4, and scanning recognition module 5 are sequentially connected by communication to form a first channel, No. 2 image sensor 2, image processing module 3, image resolution The calculation and judging module 4 and the scanning recognition module 5 are sequentially connected by communication to form a second channel, using No. 1 image sensor 1 and No. Sensor 2 identifies whether there is an image of the target to be identified within the focal length range of the currently used sensor. If it is within the focal length range of the No. 1 image sensor 1 currently used, it s...

The invention discloses a scanning device of a dual-path dual-focus sensor, including an image processing module, an image definition calculation and judgment module, a scanning recognition module, a No. 1 image sensor, and a No. 2 image sensor. The data is sent to the image processing module, the image processing module converts the data into brightness data, and outputs it to the image definition calculation and judgment module to calculate and judge which image is more suitable for sending to the scanning recognition module, and the scanning recognition module recognizes from the input image data The required image, the present invention increases the distance of scanning recognition, reduces the probability of not being recognized because the object is too far or too close to the device; during the recognition process, the recognized image content can be switched at will in the two channels , if the image in one channel cannot be recognized, it can automatically and quickly switch to another channel to speed up the speed of scanning and recognition, and improve the efficiency of scanning and recognition; the structure is simple, the operation is convenient, and the practicability is strong.
Description
technical field [0001] The invention relates to a scanning device and a scanning identification method thereof, more specifically, to a scanning device of a dual-path dual-focus sensor and a scanning identification method thereof, belonging to the field of image processing. Background technique [0002] Quick scanning to identify objects is widely used in daily life, such as one-dimensional code and two-dimensional code recognition at supermarket cashiers, barcode scanning, license plate recognition in parking lots, etc., especially with the rise of mobile payment in recent years, it is required to identify the license plate on the road Intelligent recognition, all of which put forward higher requirements for scanning devices. However, the current existing technology is a single-channel single-focus scanning device, which can only focus and scan a single object within the focal length of the sensor, and cannot scan and identify objects outside the focal length of the sensor....
