Description

Technical Field

[0001] The present application relates to the field of data processing, and in particular to a data processing method, device, chip, electronic equipment and transportation equipment. Background Art

[0002] Some video devices, such as analog cameras in surveillance systems, use interlaced scanning due to cost and bandwidth limitations. Interlaced scanning means that each image frame is divided into two fields, each field contains all odd scan lines or even scan lines in a frame. Usually, the odd lines are scanned first to get the first field, which we call the odd field, and then the even lines are scanned to get the second field, which we call the even field. In order to get a better video image effect, the receiving end needs to perform deinterlacing, that is, to restore the interlaced lines to progressive scanning.

[0003] The interlaced scanning order of different standards may be different. Some standards produce odd fields first and even fields later. Some standards produce even fields first and odd fields later. In addition, if there are force majeure such as loose wiring harness or device restart at the sender or receiver during the work process, the field information will be lost or the field will be incomplete. If the receiver is not robust enough and it is completely left to the software to judge whether it is an odd field or an even field, it is easy to cause the receiver to get the field order wrong, and the deinterlaced image will have obvious jagged edges, and even jitter and blur. Moreover, this error is irreversible unless the system is restarted or a soft reset is performed. Summary of the invention

[0047] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0048] In order to avoid field confusion (i.e., odd-even field error) or the situation where field information is lost or image frames with incomplete fields are sent for display when reading image frames captured by a camera, and to improve the robustness of data processing, an embodiment of the present application provides a data processing method, such as Figure 1 As shown, the method includes:

[0049] Step 101, read the image frame captured by the camera, and obtain actual parameters of the image frame, wherein the actual parameters include odd and even field parameters, the number of rows, and the number of pixels in each row of the image frame.

[0050] In this embodiment, the camera interface control unit (CSI, ca mera sensor interface ) to read the image frames captured by the camera, and synchronously obtain the actual parameters of the read image frames. In other implementations, any other hardware that can read the image frames captured by the camera and process the image frames can be used.

[0051] In this embodiment, the actual parameters of the image frame include odd and even field parameters, the number of rows and the number of pixels in each row of the image frame. In other implementations, the actual parameters of the image frame may include any other image parameters.

[0052] The odd and even field parameters of an image frame can characterize whether the image frame is an odd field image frame or an even field image frame. In video signal processing, the odd and even field parameters are obtained by interlaced scanning. Interlaced scanning is a video display method in which each frame of an image is divided into two fields, each field containing half the number of lines of the image, one is the odd field, which usually includes the odd lines in the image frame (1, 3, 5...). The other is the even field, which usually includes the even lines in the image frame (2, 4, 6...). The odd and even field parameters are usually represented by a field identifier. For example, when the field identifier of the odd and even field parameter is binary, 0 represents the even field and 1 represents the odd field.

[0053] Step 102, when it is determined that the image frame is an invalid frame based on preset parameters and the actual parameters, the image frame is discarded, the preset parameters include preset odd and even field parameters, a preset number of rows and a preset number of pixels per row, and the preset number of rows and the preset number of pixels per row are determined based on a preset number of image frames starting from the read.

[0054] In this embodiment, there are two situations where the image frame is an invalid frame:

[0055] The first is odd-even field error. For example, under the current standard, the odd field image frame should be output first, and then the even field image frame, but the even field image frame is output first. At this time, if it continues to be sent for display, it will cause field confusion.

[0056] The second is that the field information of the image frame is lost or the field is incomplete. For example, under the current format, the odd-field image frame should be 200 lines, each line has 1000 pixels, but the currently read odd-field image frame is 199 lines, missing a line of data. At this time, if it continues to be sent for display, the picture display will be incomplete.

[0057] In other implementations, situations where the image frame is an invalid frame may also include frame duplication, synchronization error, signal interference, color distortion, frame skipping, etc.

[0058] When the currently read image frame is determined to be an invalid frame through preset parameters and actual parameters, continuing to display it will cause display problems. Therefore, it is necessary to discard the currently read image frame and continue to read the next image frame.

[0059] Since the number of rows and the number of pixels per row of the read image frame occasionally do not match the fixed preset parameters, in this embodiment, the preset number of rows and the preset number of pixels per row in the preset parameters are determined by reading the initial preset number of image frames, so as to avoid the above situation causing errors in the determination of invalid frames.

[0060] Step 103, when the image frame is determined to be a valid frame based on preset parameters and the actual parameters, a base address corresponding to the image frame is determined based on the actual parameters, and the base address is determined based on the preset number of rows and the preset number of pixels per row.

[0061] When it is determined through the preset parameters and the actual parameters that the currently read image frame does not have the above-mentioned invalid frame, the currently read image frame is determined as a valid frame, and the base address corresponding to the image frame is determined based on the actual parameters of the image frame.

[0062] In this embodiment, it can be determined by the odd and even field parameters, the number of rows and the number of pixels in each row in the actual parameters of the image frame. For example, when the storage method is row-by-row storage, the starting address of the memory frame is B, and the number of pixels in each row is R, then the base address corresponding to the data of the i-th row in the odd-field image frame is B+(2i+1)R, where i is an integer greater than or equal to 0. The base address corresponding to the data of the j-th row in the even-field image frame is B+2jR, where j is an integer greater than 0. For another example, when the storage method is field-by-field storage, the starting address of the memory frame is B, the total number of rows of the image frame (the sum of the number of rows of the odd-field image frame and the number of rows of the even-field image frame) is H, and the number of pixels in each row is R, then the base address corresponding to the odd-field image frame is B, and the base address corresponding to the even-field image frame is

[0063] Step 104: storing the image frame into a memory frame based on the base address.

[0064] Based on the determined base address, the image frame is stored in the corresponding position in the memory frame.

[0065] In the above scheme, the actual parameters of the image frame are compared with the preset parameters to determine whether the image frame is an invalid frame or a valid frame. When the image frame is determined to be an invalid frame, the image frame is discarded. When the image frame is determined to be a valid frame, the base address corresponding to the image frame is further determined based on the actual parameters of the image frame, and then the image frame is sent for display, which effectively avoids the situation where field confusion occurs when reading the image frame captured by the camera or the image frame with lost field information or incomplete field is sent for display, improves the robustness of data processing, and significantly improves the picture quality presented after sending for display.

[0066] In an example of the present application, a data processing method is also provided, such as Figure 2 As shown, the preset parameters also include a preset identification bit, and determining that the image frame is a valid frame based on the preset parameters and the actual parameters includes:

[0067] Step 201: determine the odd and even field type of the image frame based on the odd and even field parameters of the image frame.

[0068] For example, the odd and even field parameters are represented by a field identifier. When the field identifier of the odd and even field parameters is binary, 0 represents an even field, and 1 represents an odd field.

[0069] For another example, the odd-even field parameter is represented by a field number. When the field number of an image frame is an odd number, it is an odd field image frame. When the field number of an image frame is an even number, it is an even field image frame.

[0070] Step 202, if it is determined that the preset flag indicates that a previous image frame has not been stored in the memory and the parity field type of the image frame is the same as the parity field type indicated by the preset parity field parameters, the image frame is determined to be a valid frame, and the preset flag is modified so that the preset flag indicates that a previous image frame has been stored in the memory and the parity field type of the previous image frame is the same as the parity field type indicated by the preset parity field parameters.

[0071] For example, the preset flag is 0, indicating that the previous image frame has not been stored in the memory. The odd field type indicated by the preset odd-even field parameter is odd field, and it is determined that the next image frame to be displayed under normal circumstances should be an odd field image frame. And based on the odd-even field parameter of the currently read image frame, the odd field type of the image frame is determined to be odd field, which is the same as the odd field type determined based on the preset flag and the preset odd-even field parameter, and the image frame is determined to be a valid frame. Then the preset flag is modified to 1, indicating that the previous image frame has been stored in the memory.

[0072] For another example, the preset flag is 0, indicating that the previous image frame is not stored in the memory. The odd field type indicated by the preset odd-even field parameter is odd field, and it is determined that the next image frame to be displayed should be an odd field image frame under normal circumstances. However, if the odd-even field type of the image frame is determined to be an even field based on the odd-even field parameter of the currently read image frame, which is different from the odd-even field type determined based on the preset flag and the preset odd-even field parameter, the image frame is determined to be an invalid frame.

[0073] Since the same frame of image is divided into odd and even fields in interlaced scanning, when reading the image frame, the odd and even fields should be read alternately. Therefore, in the above scheme, by presetting the identification bit and the odd and even field parameters, the correct odd and even field type of the currently read image frame can be determined, thereby realizing the monitoring of the odd and even fields of the image frame and avoiding the situation of field confusion.

[0074] In an example of the present application, a data processing method is also provided, wherein determining the image frame as a valid frame based on the preset parameters and the actual parameters includes:

[0075] If it is determined that the preset flag indicates that a previous image frame has been stored in the memory and the odd and even field type of the image frame is different from the odd and even field type indicated by the preset odd and even field parameters, the image frame is determined to be a valid frame, and the preset flag is modified so that the preset flag indicates that the previous image frame has not been stored in the memory.

[0076] For example, the preset flag is 1, indicating that the previous image frame has been stored in the memory. The odd-even field type indicated by the preset odd-even field parameter is odd field, and it is determined that the next image frame to be displayed should be an even field under normal circumstances. However, based on the odd-even field parameter of the currently read image frame, the odd-even field type of the image frame is determined to be an even field, which is different from the odd-even field type determined based on the preset flag and the preset odd-even field parameter, and the image frame is determined to be a valid frame. Then the preset flag is modified to 0.

[0077] For another example, the preset flag is 1, indicating that the previous image frame has been stored in the memory. The odd-even field type indicated by the preset odd-even field parameter is odd field, and it is determined that the next image frame to be displayed should be an even field image frame under normal circumstances. If the odd-even field type of the image frame is determined to be odd field based on the odd-even field parameter of the currently read image frame, which is the same as the odd-even field type determined based on the preset flag and the preset odd-even field parameter, the image frame is determined to be an invalid frame.

[0078] In the above scheme, by presetting the identification bit and the odd and even field parameters, the correct odd and even field type of the currently read image frame can be determined, thereby realizing the monitoring of the odd and even fields of the image frame and avoiding the situation of field confusion.

[0079] In an example of the present application, a data processing method is also provided, such as Figure 3As shown, the determining that the image frame is a valid frame based on the preset parameters and the actual parameters includes:

[0080] Step 301 : Compare the number of rows and the number of pixels in each row of the image frame with the preset number of rows and the preset number of pixels in each row.

[0081] In this embodiment, the number of pixels in each row of the image frame is the same.

[0082] Step 302: If the comparison passes, determine that the image frame is a valid frame.

[0083] If the actual total number of pixels of the image frame is the same as the preset total number of pixels, the image frame is determined to be a valid frame.

[0084] In the above scheme, if the information of the image frame is determined to be complete based on the actual number of rows, the number of pixels per row, the preset number of rows, and the preset number of pixels per row, the image frame is determined to be a valid frame. If the information of the image frame is incomplete, it is determined to be an invalid frame and discarded. This effectively avoids the situation where the field information is lost or the image frame with incomplete field is sent for display when reading the image frame captured by the camera, and improves the robustness of data processing.

[0085] In an example of the present application, a data processing method is also provided, such as Figure 4 As shown, the comparing the number of rows and the number of pixels in each row of the image frame with the preset number of rows and the preset number of pixels in each row includes:

[0086] Step 401 : determining the total number of pixels of the image frame based on the number of rows of the image frame and the number of pixels in each row.

[0087] Multiply the number of rows by the number of pixels per row to get the total number of pixels in the image frame.

[0088] Step 402: determining a standard total number of pixels based on the preset number of rows and the preset number of pixels.

[0089] Multiply the preset number of rows by the preset number of pixels per row to get the standard total number of pixels.

[0090] Step 403: compare the total number of pixels of the image frame with the standard total number of pixels.

[0091] Compare the actual total number of pixels in the image frame with the standard total number of pixels.

[0092] Step 404: If the comparison passes, determine that the image frame is a valid frame.

[0093] If the actual total number of pixels of the image frame is the same as the standard total number of pixels, the image frame is determined to be a valid frame. If the actual total number of pixels of the image frame is different from the standard total number of pixels, the image frame is determined to be an invalid frame.

[0094] In the above scheme, the actual total number of pixels of the image frame is determined based on the actual number of rows and the number of pixels in each row of the image frame. The standard total number of pixels is determined based on the preset number of rows and the preset number of pixels in each row. Then, based on the actual total number of pixels of the image frame and the standard total number of pixels, it is determined that the information of the image frame is complete, and the image frame is determined to be a valid frame. If it is determined that the information of the image frame is incomplete, it is determined to be an invalid frame and discarded. This effectively avoids the situation where the image frame with lost field information or incomplete field is sent for display when reading the image frame captured by the camera, and improves the robustness of data processing.

[0095] In an example of the present application, a data processing method is also provided, such as Figure 5 As shown, determining the base address corresponding to the image frame based on the actual parameter includes:

[0096] Step 501: Determine the odd and even field type of the image frame based on the odd and even field parameters of the image frame.

[0097] Similarly, the odd and even field parameters can be represented by a field identifier or a field number, and the odd and even field type of the image frame can be determined by the field identifier or the field number.

[0098] Step 502: If the odd-even field type of the image frame is an odd field, determine that the base address corresponding to the image frame is a first base address.

[0099] Step 503: If the odd-even field type of the image frame is an even field, determine that the base address corresponding to the image frame is a second base address, and the address space indicated by the second base address differs from the address space indicated by the first base address by one row.

[0100] For example, Figure 6 As shown, when the storage mode is row-by-row storage, the starting address of the memory frame is B, and the number of pixels in each row is R, then the first base address corresponding to the data of the first row in the odd-field image frame is B, and the first base address corresponding to the data of the third row in the odd-field image frame is B+2R, and so on, the first base address corresponding to the data of the i-th row in the odd-field image frame is B+2iR, where i is an integer greater than or equal to 0. The second base address corresponding to the data of the second row in the even-field image frame is B+R, and the second base address corresponding to the data of the fourth row in the even-field image frame is B+3R, and so on, the second base address corresponding to the data of the j-th row in the even-field image frame is B+(2j+1)R, where j is an integer greater than 0.

[0101] For example, Figure 7As shown in the figure, when the storage mode is field-by-field storage, the starting address of the memory frame is B, the total number of lines of the image frame (the sum of the number of lines of the odd field image frame and the number of lines of the even field image frame) is H, and the number of pixels in each line is R. Then, the first base address corresponding to the odd field image frame is B, and the second base address corresponding to the even field image frame is B+6R. Similarly, the second base address corresponding to the even field image frame can be expressed as

[0102] In the above scheme, by determining the odd and even field type of the image frame and then determining the base address corresponding to the image frame, the image frame can be correctly stored in the memory frame and then sent for display.

[0103] In an example of the present application, a data processing method is also provided, including:

[0104] The preset number of image frames at the beginning of reading are blocked, i.e. they are not sent for display.

[0105] Since the camera may send some frames with disordered field sequence numbers when it is just started or restarted, shielding the first multiple image frames to be read can further improve the robustness of data processing.

[0106] In order to implement the above data processing method, Figure 8 As shown, an example of the present application provides a data processing device, including:

[0107] The transmission module 10 is used to read the image frame collected by the camera and obtain the actual parameters of the image frame, wherein the actual parameters include the odd and even field parameters, the number of rows and the number of pixels per row of the image frame;

[0108] A processing module 20, configured to discard the image frame if it is determined that the image frame is an invalid frame based on preset parameters and the actual parameters, the preset parameters including preset odd and even field parameters, a preset number of rows and a preset number of pixels per row, the preset number of rows and the preset number of pixels per row being determined based on a preset number of image frames starting from reading;

[0109] The processing module 20 is further configured to determine a base address corresponding to the image frame based on the actual parameter when the image frame is determined to be a valid frame based on the preset parameter and the actual parameter, wherein the base address is determined based on the preset number of rows and the preset number of pixels per row;

[0110] The transmission module 10 is further configured to store the image frame into a memory frame based on the base address.

[0111] Wherein, the processing module 20 is further used to determine the odd and even field type of the image frame based on the odd and even field parameters of the image frame;

[0112] The processing module 20 is further used to determine that if the preset flag indicates that the previous image frame has not been stored in the memory and the parity field type of the image frame is the same as the parity field type indicated by the preset parity field parameters, then determine that the image frame is a valid frame, and modify the preset flag so that the preset flag indicates that the previous image frame has been stored in the memory, and the parity field type of the previous image frame is the same as the parity field type indicated by the preset parity field parameters.

[0113] Among them, the processing module 20 is also used to determine that the preset flag indicates that a previous image frame has been stored in the memory and the parity field type of the image frame is different from the parity field type indicated by the preset parity field parameters, then determine that the image frame is a valid frame, and modify the preset flag so that the preset flag indicates that the previous image frame has not been stored in the memory.

[0114] Wherein, the processing module 20 is further used to compare the number of rows and the number of pixels in each row of the image frame with the preset number of rows and the preset number of pixels in each row;

[0115] The processing module 20 is further configured to determine that the image frame is a valid frame if the comparison passes.

[0116] Wherein, the processing module 20 is further used to determine the total number of pixels of the image frame based on the number of rows of the image frame and the number of pixels in each row;

[0117] The processing module 20 is further used to determine a standard total number of pixels based on the preset number of rows and the preset number of pixels;

[0118] The processing module 20 is further used to compare the total number of pixels of the image frame with the standard total number of pixels;

[0119] The processing module 20 is further configured to determine that the image frame is a valid frame if the comparison passes.

[0120] Wherein, the processing module 20 is further used to determine the odd and even field type of the image frame based on the odd and even field parameters of the image frame;
