Embodiment Construction

[0037] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0038] Please refer to figure 1 , which shows a method flow chart of an image data acquisition method provided by an embodiment of the present application, such as figure 1 As shown, the method includes:

[0039] Step 101, performing serial-to-parallel conversion on the image data generated by the line-scan camera;

[0040] Optionally, 16 pairs of LVDS (Low-Voltage Differential Signaling, Low-Voltage Differential Signaling) signals corresponding to 16 channels are serial-to-parallel converted, and finally the pixel gray value represented by 12 bits (bits) is obtained from each channel.

[0041] combine figure 2 , which shows a schematic diagram of performing serial-to-parallel conversion...

Abstract

This application relates to an image data acquisition method and device, belonging to the technical field of logistics systems, including: serial-to-parallel conversion of the image data generated by the line array camera; first-level buffer conversion of the serial-to-parallel converted image data to obtain the second Image data; converting the first image data into a second-level cache to obtain second image data. The problem of poor operation stability of the industrial camera and high power consumption in the prior art is solved, and the effect of improving the operation stability of the industrial camera and reducing power consumption is achieved. Specifically, by adopting 96-bit wide data and synchronously receiving a clock twice the clock frequency of the industrial camera, the stability of the camera is ensured, power consumption is reduced and the heat dissipation of the camera is reduced so that the heat dissipation can meet the demand.

Description

technical field [0001] The application relates to an image data collection method and device, and belongs to the technical field of logistics systems. Background technique [0002] At present, most of the existing logistics sorting systems in China use area array industrial cameras with 5 area array scanning. When workers place packages on the trolley for delivering parcels, they need to ensure that the parcel list cannot face down, otherwise they cannot be photographed by the area array industrial cameras. This reduces the work efficiency of workers. If you can use the line array camera to scan and take pictures in the gap between the two trolleys on the bottom surface, then you can perform six-sided array codes, thereby greatly improving the efficiency of parcel sorting. At this time, the line scan industrial camera must ensure that the scanned image has a large enough field of view (the width of the trolley is more than 1.10m) and a high enough resolution (generally requ...
