Rapid image acquisition method for express delivery mobile terminal

Abstract

The invention relates to the technical field of bar code scanning, and particularly discloses a quick image acquisition method for an express delivery mobile terminal, and the method comprises the steps: achieving the acquisition of an original image through optimizing the parameters of a Camera sensor, a fixed frame rate, a fixed gain and skipping a platform ISP processing scheme, enabling the express delivery mobile terminal to obtain the ID of a scanning engine, obtaining the imgbuffer memory address of a pass1, obtaining the original image obtained by the Camera sensor through the pass1, and enabling the express delivery mobile terminal to obtain the original image obtained by the camera sensor through the imgbuffer memory address of the pass1. The method comprises the following steps: converting an original image into an RAW8 format, sending the converted original image into an image average brightness algorithm process, realizing rapid exposure processing of the original image, rapidly obtaining a clear bar code image, obtaining an imgbuffer virtual memory address of a Pass2, writing the original image obtained by the Pass1 into the imgbuffer virtual memory of the Pass2, and returning the original image in the Pass2 to an application layer. And the application layer part of the scanning engine obtains the returned original image and sends the original image to the decoding library, and the decoding library outputs the decoding result to obtain the bar code information, so that the accuracy of obtaining the commodity information is improved, the working efficiency of the scanning engine is effectively enhanced, and the social requirements are met.

Description

technical field [0001] The invention relates to the technical field of barcode scanning, in particular to a fast image acquisition method for express delivery mobile terminals. Background technique [0002] In the prior art, the express mobile terminal device integrates a scan engine driver and a decoding library, sends control commands through the I2C protocol to control the scan engine, returns data information through mipi, and finally obtains barcode information quickly through the terminal decoding library. [0003] The scanning engine is a special device used to identify and process barcode label information to classify and trade commodities. The scan engine generally consists of a main board, a camera assembly, a fill light and an aiming light to form a hardware module, and the main board provides a power supply interface, an I2C interface for accessing express mobile terminal equipment, and a MIPI interface. [0004] At present, scan engines are widely used in all w...

Problems solved by technology

[0004] At present, scanning engines are widely used in all walks of life, especially in express logistics, medical electronics and other industries. In order to improve the speed of express logistics and accelerate the information acquisition of medical electronics, scanning engines need to read a large number of one-dimensional However, the red light emitted by the aiming light of the scanning engine on the market can easily affect the image on the barcode, and when the scanning environment is too heavy or too dark, the accuracy of the scanning engine to obtain product information is low, and the barcode The reading speed is relatively slow and cannot meet the current social needs
