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...

The invention relates to an image data acquisition method and device, and belongs to the technical field of logistics systems. The method comprises the steps of carrying out the serial-parallel conversion on the image data generated by a linear array camera; performing first-level cache conversion on the image data subjected to serial-parallel conversion to obtain the first image data; and performing second-level cache conversion on the first image data to obtain the second image data, so that the problems of worse operation stability and higher power consumption of an industrial camera in theprior art are solved, and the effects of improving the operation stability of the industrial camera and reducing the power consumption are achieved. Specifically, by adopting the 96-bit wide data, and meanwhile, by adopting a clock of which the clock frequency is twice of the clock frequency of the industrial camera to receive synchronously, the stability of the camera is ensured, the power consumption is reduced, the heat dissipation of the camera is further reduced, and the effect that the heat dissipation meets the requirement is achieved.
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...
