DETAILED DESCRIPTION

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0024] like Figure 1-Figure 5 As shown, the camera for express sorting provided in this embodiment includes: a camera body 1, in which a main control board 2 and a camera assembly 3 are arranged.

[0025] The camera assembly 3 is used to collect image information of the target object, and includes a lens 301 and an image acquisition board 302 that cooperate with each other, and an image sensor 303 is integrated on the image acquisition board 302. The lens 301 focuses the optical image onto the image sensor 303 on the image acquisition board 302.

[0026] The main control board 2 and the image sensor 303 are connected via the MIPI interface 4, so that the image sensor 303 transmits the collected raw image data to the main control board 2 via the MIPI interface 4 for subsequent processing.

[0027] The MIPI interface 4 has the characteristics of high bandwidth and low power consumption, and can greatly improve the data transmission rate and efficiency between the image sensor 303 and the main control board 2, thereby achieving high-speed and high-quality image acquisition.

[0028] The bottom surface of the camera body 1 is provided with a groove 5, and a through hole 6 is passed upward through the middle of the groove 5. The lens 301 is located in the through hole 6 to cooperate with the image acquisition board 302. The fill light 7 is arranged in the groove 5, surrounding the lens 301, and is used to provide additional lighting to ensure that the camera assembly 3 can clearly capture the image of the target object.

[0029] In this embodiment, the camera body 1 is square in shape as a whole, and the groove 5 is rectangular in shape. The bottom end of the lens 301 does not exceed the bottom surface of the groove 5. The wall surface of the groove 5 surrounds the lens 301, forming a structure similar to a "light shield".

[0030] This structure can block ambient stray light from the side of the lens 301 to a certain extent, reduce light interference and glare, and thus improve the contrast and clarity of the imaging.

[0031] In this embodiment, the image sensor 303 is an industrial CMOS image sensor, which has higher reliability, stability and durability than ordinary CMOS image sensors.

[0032] Industrial CMOS image sensors have higher resolution and faster frame rate. High resolution ensures that the captured images are detailed and clear, while high frame rate supports high-speed continuous shooting, avoiding blurring of fast-moving objects. These two points play a positive role in the speed and accuracy of express sorting.

[0033] In addition, industrial CMOS image sensors have a wider dynamic range and can still capture details in dark areas under complex lighting conditions, thus ensuring the integrity of image information and facilitating subsequent operations such as barcode recognition.

[0034] In this embodiment, the main control board 2 adopts a CPU solution based on the MTK6762 chip. By adopting a CPU solution based on this chip, its powerful computing power can be used to achieve more efficient image processing and analysis. The CPU solution cooperates with the MIPI interface between the main control board 2 and the image sensor 303 to achieve high-speed, high-quality image acquisition and processing.

[0035] In this embodiment, the image sensor 303 is an industrial CMOS image sensor, and the main control board 2 adopts a CPU solution based on the MTK6762 chip, which provides a highly reliable, high-quality, high-performance, and high-efficiency hardware foundation from the two aspects of image acquisition and image processing, and provides support for fast and accurate image acquisition and processing needs.

[0036] In this embodiment, a protective ring 8 is disposed above the through hole 6, and the protective ring 8 forms a cylindrical inner cavity 801 with a certain height in the camera body 1. The image acquisition board 302 is disposed in the inner cavity 801 and is protected and limited by the protective ring 8.

[0037] In this embodiment, the fill light 7 includes a plurality of LED lamp beads, which are specifically divided into: an inner circle LED lamp beads 701 evenly arranged along a first rectangular path and an outer circle LED lamp beads 702 evenly arranged along a second rectangular path.

[0038] The lens 301 is located at the common center of the first rectangular path formed by the inner circle LED lamp beads 701 and the second rectangular path formed by the outer circle LED lamp beads 702 , so that the fill light 7 surrounds the lens 301 .

[0039] The inner and outer circle design of the fill light 7 enables the camera assembly 3 to clearly capture the target image even when used in an environment with insufficient ambient light.

[0040] In this embodiment, the main control board 2 is respectively connected to a USB interface group, a communication interface unit, an audio and video output unit, a storage expansion unit and a Type-C universal expansion unit.

[0041] Among them, the USB interface group, communication interface unit and audio and video output unit are arranged on the left side of the camera body 1, and the storage expansion unit and Type-C universal expansion unit are arranged on the right side of the camera body 1. This left-right layout makes the arrangement of various interfaces and units more reasonable and convenient for user operation.

[0042] In this embodiment, the USB interface group includes a first USB interface 1201 and a second USB interface 1202 arranged vertically, which can meet the connection requirements of different peripherals.

[0043] In this embodiment, the communication interface unit includes a DB9 interface 901 for serial communication, an M12 aviation interface 902 for connecting customized peripherals, and an Ethernet interface 903 for network communication. The DB9 interface 901 can communicate serially with a PLC or other industrial control equipment to transmit control and status information.

[0044] In this embodiment, the audio and video output unit includes an HDMI interface 1001 and an audio interface 1002, which are used for outputting video and audio respectively. The HDMI interface 1001 can be connected to a high-definition display device to display the shooting picture or processing results in real time.

[0045] In this embodiment, the storage expansion unit is in the form of a TF card slot 1101, which can expand the storage space.

[0046] In this embodiment, the Type-C universal extension unit is specifically a Type-C interface 1102, which can be used for data transmission or powering the camera.

[0047] In this embodiment, after the main control board 2 receives the image data transmitted by the MIPI interface 4, the image is optimized by the built-in ISP module (not shown in the drawings), and then the integrated barcode recognition module (not shown in the drawings) performs analysis and recognition to extract the barcode information. The processed image data and recognition results can be transmitted to other devices through the interface on the main control board 2 (such as the USB interface group, audio and video transmission unit, etc.).

[0048] In this embodiment, the working process of camera image acquisition and barcode recognition is as follows:

[0049] 1. After the camera is powered on, the MIPI Host of the main control board 2 (based on ARM MTK6762 CPU) performs initialization configuration, including setting parameters such as the number of lanes and transmission rate.

[0050] 2. The CMOS image sensor is powered on and completes internal initialization. The resolution, frame rate, data format, etc. of the image acquisition are set according to preset or dynamic configuration.

[0051] 3. The MIPI Device of the CMOS image sensor establishes a connection with the MIPI Host of the main control board 2 to complete the synchronization and handshake process.

[0052] 4. The main control board 2 sends an image acquisition instruction to the CMOS image sensor, and the sensor starts to acquire images according to the set parameters. The optical image of the object being photographed is focused on the photosensitive surface of the CMOS image sensor through the lens 301, and the sensor converts the optical signal into a digital signal.

[0053] 5. The collected raw image data is transmitted to the main control board 2 at high speed through the MIPI interface 4. Thanks to the high bandwidth characteristics of the MIPI interface 4, even high-resolution images can be transmitted with low latency.

[0054] 6. The ISP (Image Signal Processor) module of the main control board 2 processes the received raw image data, such as white balance, exposure correction, noise reduction, etc., to optimize the image quality.

[0055] 7. The processed image is analyzed by the barcode recognition module of the main control board 2. This module runs the barcode positioning and recognition algorithm to find and extract the barcode information in the image.

[0056] 8. The identified barcode information can be further used in applications such as express sorting, or transmitted to other devices through the interface on the main control board 2.

[0057] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
