The analog-to-digital conversion module 201 is configured to receive analog image data acquired by an image acquisition device and private data corresponding to the analog image data; performing analog-to-digital conversion on the analog image data to obtain digital image data; adding private data corresponding to the received analog image data into the digital image data to obtain an image data packet; sending the image data packet to the main chip 202 through the serial interface 203;
the main chip 202 is configured to parse the received image data packet to obtain digital image data and/or private data.
By applying the embodiment of the application, the analog-to-digital conversion module performs analog-to-digital conversion on the received analog image data to obtain the digital image data, the private data corresponding to the received analog image data is added into the digital image data, and the analog-to-digital conversion module is connected with the main chip by using the serial interface, so that the data transmission capability of the interface is enhanced, the normal transmission of an image data packet with larger data volume can be ensured, and the mixed transmission of the image data and the private data is realized.
The image acquisition equipment has an image acquisition function, and also has functions of intelligent early warning, intelligent detection, alarm analysis and the like, so that after the image acquisition equipment acquires the analog image data, the image acquisition equipment can perform intelligent early warning, intelligent detection, alarm analysis and other processing on the analog image data to generate private data corresponding to the analog image data, and the private data can comprise early warning information, a target detection result, alarm information and the like. The image capturing device may transmit both the captured analog image data and the generated private data to the image data processing device. The analog image data may be a frame of image data in the video data acquired by the image acquisition device, and the analog image data and the private data have a one-to-one correspondence relationship.
The image data mentioned in the embodiment of the present application refers to the main content of analog signal transmission, and the original image acquired by the image acquisition device is converted into analog signals of chrominance signals and luminance signals, and the analog signals are received by the image data processing device and then converted into digital signals in YUV format, RGB format, and other formats.
The image data processing apparatus is an electronic apparatus having functions of analog-to-digital conversion, data storage, and the like, and may be, for example, a DVR. The image data processing equipment comprises an analog-to-digital conversion module (A/D converter) and a main chip (SoC), wherein the analog-to-digital conversion module is responsible for receiving analog image data and private data corresponding to the analog image data, performing analog-to-digital conversion on the analog image data, adding the received private data into the digital image data obtained after conversion to obtain an image data packet, and sending the image data packet to the main chip through a serial interface. Because the analog-to-digital conversion module and the main chip are connected through the serial interface, when the received private data is added to the digital image data, the private data needs to be added to the digital image data according to the interface standard specified by the serial interface.
In one implementation of the embodiments of the present application, the serial interface 203 may be a mobile industry processor interface.
The serial Interface used between the analog-to-digital conversion module and the main chip may be MIPI (Mobile Industry Processor Interface), where MIPI is an open standard initiated by an MIPI alliance and specified for a Mobile application Processor, and MIPI is a serial Interface for data transmission in units of data packets. Under general conditions, the interface capability of the MIPI is strong, and a data packet with a large data volume can be transmitted, so that the analog-to-digital conversion module and the main chip are connected through the MIPI, and normal transmission of the data packet with the large data volume can be ensured.
In an implementation manner of the embodiment of the present application, when the analog-to-digital conversion module 201 is configured to add private data corresponding to received analog image data to digital image data to obtain an image data packet, the analog-to-digital conversion module may be specifically configured to: and/or adding private data corresponding to the received analog image data at the head and/or tail of the digital image data to obtain an image data packet.
Correspondingly, the main chip 202, when being used for parsing the received image data packet to obtain digital image data and/or private data, may be specifically used for: identifying the data of the head and the tail in the image data packet to obtain private data; and/or identifying data except the head and the tail in the image data packet to obtain digital image data.
In serial interface standards such as MIPI, it is agreed that the manner of adding private data to digital image data may be: private data is added at the head and/or tail of the digital image data. That is to say, after performing analog-to-digital conversion on analog image data, the analog-to-digital conversion module may add the received private data to the head and/or the tail of the converted digital image data, and when specifically adding, may add all the private data to the head of the digital image data, may add all the private data to the tail of the digital image data, and may add a part of the private data to the head of the digital image data and a part of the private data to the tail of the digital image data.
Therefore, the analog-to-digital conversion module can transmit the obtained image data packet to the main chip through the serial interface, and after the main chip receives the image data packet, the main chip can identify the data of the head and the tail in the image data packet to obtain private data and/or identify the data except the head and the tail in the image data packet to obtain digital image data.
In an implementation manner of the embodiment of the present application, the analog-to-digital conversion module 201 may be further configured to: adding a first identification code of the private data at a position corresponding to the private data in the image data packet; and/or adding a second identification code of the digital image data at a position corresponding to the digital image data in the image data packet.
Correspondingly, the main chip 202, when being used for analyzing the received image data packet to obtain the digital image data and the corresponding private data thereof, may be specifically used for: identifying private data from the image data packet based on the first identification code; and/or identifying digital image data from the image data packet based on the second identification code.
The position corresponding to the private data refers to a position where a preset first mapping relationship is satisfied with a position where a field carrying the private data is located, where the first mapping relationship may be different according to different actual requirements, for example, if the field carrying the private data is a continuous field, the position corresponding to the private data may refer to a position of a preset number of bits (bit) before or after the continuous field, or for example, if the field carrying the private data is a field composed of multiple discontinuous subfields, the position corresponding to the private data may refer to a position before or after all discontinuous subfields, or may refer to a position between any two discontinuous subfields, and for example, assuming that the field carrying the private data is a field composed of two discontinuous subfields, for convenience of description, the two discontinuous subfields are respectively denoted as subfield 1 and subfield 2, and assuming that sub-field 1 precedes sub-field 2, the corresponding location of the private data may refer to a location that is a first preset number of bits after sub-field 1 and a second preset number of bits before sub-field 2. When the main chip 202 parses the received image data packet, a field carrying the private data may be determined according to the position of the first identification code obtained by parsing and the first mapping relationship, and the private data is obtained by parsing the field.
Similarly, the position corresponding to the digital image data may refer to a position where a preset second mapping relationship is satisfied between positions where the fields carrying the digital image data are located, where the second mapping relationship may be different according to different actual requirements, and the second mapping relationship may be the same as or different from the first mapping relationship.
The user can customize the identification codes of different types of data, namely the identification code of the private data is the first identification code, and the identification code of the digital image data is the second identification code, the analog-to-digital conversion module can also add the first identification code of the private data at the position corresponding to the private data in the image data packet, add the second identification code of the digital image data at the position corresponding to the digital image data in the image data packet, and specifically can add the first identification code at the start of the private data and add the second identification code at the start of the digital image data.
Thus, after receiving the image data packet, the main chip can identify the private data from the image data packet based on the first identification code and/or identify the digital image data from the image data packet based on the second identification code.
Certainly, the analog-to-digital conversion module can add an identification code in the digital image data, and can also add information such as the data length of the private data and the data length of the digital image data, so that the private data and the digital image data can be analyzed more accurately and quickly when the main chip performs data analysis.
In an implementation manner of the embodiment of the present application, there are a plurality of pieces of private data corresponding to the analog image data. Correspondingly, when the analog-to-digital conversion module 201 is configured to add the received private data corresponding to the analog image data to the digital image data to obtain the image data packet, the analog-to-digital conversion module may be specifically configured to: adding each piece of private data and the first identification code of each piece of private data to each line of the head and/or each line of the tail of the digital image data respectively to obtain an image data packet; and adding a second identification code of the digital image data at a position corresponding to the digital image data in the image data packet.
Correspondingly, the main chip 202, when being used for analyzing the received image data packet to obtain the digital image data and the corresponding private data thereof, may be specifically used for: identifying each piece of private data from the head and the tail in the image data packet based on each first identification code; and/or identifying digital image data from the image data packet based on the second identification code.
The image acquisition device can have multiple expansion functions, so that multiple types of private data can be generated, a user can also customize identification codes of different types of private data, namely one piece of private data has one first identification code, when the analog-to-digital conversion module generates an image data packet, each piece of private data and the first identification code of each piece of private data can be added to each line at the head and/or each line at the tail of the digital image data respectively, and a second identification code of the digital image data is added to a position corresponding to the digital image data in the image data packet.
Thus, after receiving the image data packet, the main chip can identify each piece of private data from the head and the tail of the image data packet based on each first identification code, and/or identify digital image data from the image data packet based on the second identification code.
In an implementation manner of the embodiment of the present application, the main chip 202 may further be configured to: and processing the digital image data according to the private data.
Since the private data may include the early warning information, the target detection result, the alarm information, and the like, after the digital image data and the corresponding private data are obtained by the analysis of the main chip, the digital image data may be correspondingly processed by using the private data, for example, the private data may be displayed simultaneously when the digital image data is displayed; alternatively, an alarm or the like may be given while the digital image data is displayed.
The main chip may be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like; but also a DSP (Digital Signal Processing), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array) or other Programmable logic device, discrete Gate or transistor logic device, discrete hardware component; it may also be a SoC.
Based on the above embodiments, the image data processing apparatus provided in the embodiments of the present application is applied to the monitoring system as shown in fig. 3, and the monitoring system includes an analog camera and an image data processing apparatus.
The analog camera is an intelligent analog camera and can generate private data, after the analog camera collects analog image data and correspondingly generates the private data corresponding to the analog image data, the analog camera transmits the analog image data and the private data to an image data processing device (DVR shown in the figure) through analog signal transmission lines such as a coaxial video cable and a twisted pair, the image data processing device comprises an A/D converter and an SoC, the A/D converter is used for receiving the analog image data and the private data, performing analog-to-digital conversion on the analog image data, and adding the private data into the digital image data obtained after the conversion to obtain an image data packet, the structure of the image data packet is shown in figure 4, the private data is added at the head (namely a frame head) and/or the tail (namely a tail frame) of the digital image data, and the digital image data and the frame head, the frame, the, The data outside the frame end is blanking data. After the image data packet is obtained, the A/D converter sends the image data packet to the SoC through the MIPI, the SoC identifies the data of the head and the tail in the image data packet to obtain private data, and the data except the head and the tail in the image data packet is identified to obtain digital image data.
Taking the MIPI CSI2 standard (interface standard specified by the camera working group under the MIPI alliance) as an example, the image data packet is introduced, and in the byte-packing layer protocol, the structures of the synchronization signal short packet and the data long packet are defined. The short packet of the synchronization signal is used to transmit synchronization information, which includes three parts, namely Data ID (Data ID), WC (Word Count) and ECC (Error Correcting Code). The synchronization information includes a line sync and a field sync. Data ID field, containing VC (Virtual Channel) and DT (Data Type) definitions. The definition of DT is shown in Table 1, where 0x 30-0 x37 is used for user-defined data types, and the private data types in the embodiment of the present application take the values here.
TABLE 1 DT definition
The data long packet is used for transmitting effective pixel data of an image and is divided into three parts: a header, valid data, and a trailer. Wherein, the packet header comprises a Data ID, a Data length and an ECC; the trailer contains a checksum.
The packet header consists of 8-bit Data ID, 16-bit WC and 8-bit ECC; the Data ID is composed of a 2-bit VC number and a 6-bit DT. VC can be used for multi-path composite data packaging, at most 4MUX is supported, DT is used for mixed data transmission of YUV data and image data, and private data transmission. ECC allows the first 24 bits (Data ID and WC) in the header to be found with two bits in error and one bit in error corrected during transmission. The WC is the number N of bytes of image data in the long packet, and the WC in the short packet is defaulted to 0 or is self-defined. The maximum value is 0XFFFF (65535).
In fig. 4, the header and the FE trailer are short packets, and the valid pixels and private data are transmitted using long packets. The header of each row is 32 bits, and contains information such as VC and DT of the current row. Generally, one row of data is packed in one long packet. Examples are: for 1080P25 video, there are 1080 lines of data in one frame of image, 1920 pixel point data in each line, and packing is performed in units of line data. The frame image packet structure may be: frame header short packet + N private data long packets +1080 image data long packets + N private data long packets + frame trailer short packet. The value range of N is 0 to a plurality of N, and generally one frame of image has 1-2 private data long packets.
