Based on the projector, the embodiments of the method for self-checking the abnormality cause of the projected image are provided.
In each embodiment of the self-checking method for the abnormal cause of the projected image, the self-checking method for the abnormal cause of the projected image is applied to the projector which is provided with the projector module, the main board and the RGB camera. As shown in fig. 3, in a usage scenario of the method for self-checking the abnormal cause of the projected image according to the present invention, a projector module of the projector is connected to a main board through a Flexible Printed Circuit (FPC), and the projector mainly has two projection modes, one of which is to store an image in a memory of the projector module configured by the projector module, and then automatically project the image in the memory to a desktop projection area according to a main board instruction; and the other mode is that the processed image is transmitted to a projector module through the MIPI by the mainboard, and then the projector projects the image on a projection area on a desktop or a wall surface.
Referring to fig. 2, fig. 2 is a schematic flow chart of a self-checking method for the cause of abnormality of a projected image according to a first embodiment of the present invention. In a first embodiment of the self-inspection method for the cause of abnormality of the projected image of the present invention, the self-inspection method for the cause of abnormality of the projected image of the present invention includes:
step S10: when a projector self-inspection instruction is detected, projecting a standard color image to a projection area through the projector module, wherein the standard color image is stored in a preset memory;
in this embodiment, when the projector detects a projector self-check instruction, the projector immediately projects a standard color image stored in a preset memory to a projection area on a desktop or a wall surface through its own projector module.
It should be noted that, in this embodiment, the preset memory includes: the first memory of the projector module and the second memory built in or externally connected with the mainboard. The standard color image projected to the projection area by the projector through the projector module comprises: a first standard color image stored in the first memory, and a second standard color image stored in the second memory.
Further, in a possible embodiment, the step S10 may include:
projecting the first standard color image to a projection area through the projector module; or,
and projecting the second standard color image to a projection area through the projector module.
In this embodiment, when the projector detects a self-checking instruction of the projector, the projector immediately projects a first standard color image stored in a memory of the projector module to a projection area on the desktop through its own projector module, and projects a second standard color image processed by its own motherboard and transmitted to the projector module to the projection area.
It should be noted that, in this embodiment, the projector body may detect a projector self-test instruction triggered by a user when the user starts a self-test function preset by the user, or the projector body may also automatically trigger the projector self-test instruction according to a preset time period. It should be understood that, based on different design requirements of practical applications, in different possible embodiments, the projector may set different time periods, and the method for self-checking the cause of the abnormality of the projected image according to the present invention is not limited to a specific size of the time period.
In addition, in this embodiment, as shown in fig. 5, the first standard color image and/or the second standard color image may specifically be rich-color pictures including red, green, blue, white, black, and the like, and particularly, the more complicated the color of the second standard color image, the larger the amount of data transmitted by the motherboard to the projector module through the MIPI is, so that the quality of the second standard color image projected by the projector module is lower than that of a single-color picture (only one of the red, green, blue, white, black, and the like), and thus the possibility that the projected image is abnormal (as shown in fig. 6, the dotted line of the black oval frame is an abnormal situation that may occur — the abnormal line may flicker and jitter) is higher.
Step S20, acquiring an image of the projection area through the RGB camera to obtain image data containing the standard color image;
in this embodiment, in the process that the projector projects the standard images to the projection areas on the desktop through the projector module, the projector acquires the images of the projection areas on which the standard color images are projected through its own RGB camera, so as to obtain image data including the standard color images.
In this embodiment, the image data acquired by the projector with respect to the projection area by the RGB camera includes: first image data including the first standard color image, and second image data including the second standard color image.
Based on this, the step S20 may include:
when the first standard color image is projected to the projection area through the projector module, image acquisition is carried out on the projection area through the RGB camera to obtain first image data containing the first standard color image; or,
when the second standard color image is projected to the projection area through the projector module, image acquisition is carried out on the projection area through the RGB camera to obtain second image data containing the second standard color image;
in this embodiment, in the process that the projector projects the first standard color image and the second standard color image onto the projection area on the desktop through the projector module, the projector performs image acquisition on the projection area projected with the first standard color image through its own RGB camera to obtain first image data including the first standard color image, and performs image acquisition on the projection area projected with the second standard color image through its own RGB camera to obtain second image data including the second standard color image.
Further, in this embodiment and other possible embodiments described later, the step of "performing image acquisition on the projection area by the RGB camera" in step S20 may include:
after the first standard color image or the second standard color image is projected to the projection area through the projector module, the RGB camera is used for continuously acquiring images of the projection area within a preset time.
It should be noted that, in this embodiment, the preset duration is a duration for which the projector sets in advance that the RGB camera continuously operates to perform image acquisition operations such as continuous photographing and shooting for the projection area, it should be understood that, based on different design requirements of practical applications, in different feasible embodiments, the projector may set different durations for the RGB camera to perform image acquisition for the projection area, and the method for self-detecting the abnormality cause of the projection image according to the present invention is not limited to a specific size of the preset duration.
For example, assuming that the preset time is 30s, as shown in fig. 3, after the projector triggers a self-test instruction generated when a user starts a self-test function, the projector first projects a first standard color image (including red, green, blue, white, black and other colors) stored in a memory of the projector to a projection area of a desktop through a projector module, and continuously photographs the projection area for 30s through an RGB camera, so as to obtain first image data including the first standard color image. Then, the projector transmits 3 second standard color images (such as the colorful pictures shown in fig. 5) to the projector module through the motherboard by using the MIPI signal, so that the projector module projects the three images to the projection area on the desktop respectively, and the RGB camera synchronously takes pictures of the projection area for 30 seconds, thereby obtaining second image data including each second standard color image.
And step S30, detecting whether the projector has a fault or not according to the image data, and performing exception handling and/or outputting prompt information when the projector has the fault.
In this embodiment, after the projector respectively performs image acquisition by the RGB camera to obtain the image data, the projector further respectively performs image analysis on the image data to determine whether or not it is faulty. And when the projector module or the mainboard with the fault is determined to have the fault, abnormal processing is immediately carried out or corresponding prompt information is output aiming at the projector module or the mainboard with the fault.
Further, in a possible embodiment, the step S30 of "detecting whether the projector is in failure according to the image data" may include:
step S301, performing image analysis on the first image data and the second image data to obtain an image analysis result;
step S302, detecting the image analysis result to determine that the projector module has a fault or determine that the main board has a fault.
In the present embodiment, after the projector performs image acquisition by the RGB camera to obtain the above-mentioned first image data and second image data, image analysis is performed on the first image data and the second image data, respectively, so as to obtain an image analysis result of whether there is an abnormality such as the above-mentioned "abnormal line flicker and shake" in each of the first image data and/or the second image data. In this way, the projector may correspondingly determine that the projector module of the projector has a failure or the main board of the projector has a failure based on whether the first image data and/or the second image data indicated by the image analysis result are/is abnormal.
Further, in a possible embodiment, the step S302 may specifically include:
if the image analysis result is detected that the first image data is abnormal and the second image data is not abnormal, determining that the projector module breaks down;
or,
and if the image analysis result is detected that the first image data is not abnormal and the second image data is abnormal, determining that the main board has a fault.
In this embodiment, when the projector analyzes the first image data and the second image data to determine whether the projector module and the motherboard are faulty, if an image analysis result obtained by performing image analysis on the first image data and/or the second image data is: if the first image data has an abnormality such as "abnormal line flicker and jitter" but the second image data has no abnormality, the projector can determine that the projector module currently has a fault. Or, if an image analysis result obtained by performing image analysis on the first image data and/or the second image data is: if the second image data has an abnormality such as "abnormal line flicker and jitter" but the first image data has no abnormality, the projector can determine that the main board of the projector is currently faulty.
Further, in a possible embodiment, in the process that the projector performs image analysis according to the first image data and the second image data to determine whether a failure occurs in its projector module or to determine whether a failure occurs in its main board, if it is determined that the failure occurs in the projector module, the projector immediately performs exception handling and/or outputs prompt information for the projector module, and similarly, if it is determined that the failure occurs in the main board, the projector immediately performs exception handling and/or outputs prompt information for the main board.
It should be noted that, in this embodiment, the projector performs exception handling on the projector module or the motherboard that has a fault, specifically, corresponding firmware upgrade handling may be performed on the projector module or the motherboard. It should be understood that, based on different design requirements of practical applications, in different possible embodiments, the projector may also perform the above-mentioned exception handling on the failed projector module or motherboard in other possible manners, for example, as a possible embodiment, in a case that the projector is configured with a spare projector module and/or motherboard, the projector may specifically automatically switch to use the spare projector module to perform exception handling on the failed projector module, and automatically switch to use the spare motherboard to perform exception handling on the failed motherboard.
In this embodiment, according to the method for self-checking the abnormal cause of the projected image, when the projector detects the projector self-checking command, the projector immediately projects the standard color image stored in the preset memory to the projection area on the desktop or the wall surface through its own projector module. In the process that the projector projects the standard images to the projection areas on the desktop through the projector module, the projector acquires images of the projection areas projected with the standard color images through the RGB camera of the projector, so that image data containing the standard color images are obtained.
After the projectors respectively acquire images through the RGB cameras to obtain the image data, the projectors further respectively perform image analysis on the image data to determine whether the projectors themselves have a fault. And when the projector module or the main board which has the fault is determined to have the fault, exception processing is immediately carried out or corresponding prompt information is output aiming at the projector module or the main board which has the fault.
Therefore, the projector projects the standard color image and collects the image data comprising the standard color image, so as to detect whether the projector module and the main board respectively have faults according to the image data, thereby realizing automatic detection aiming at the reasons of abnormal phenomena such as linear flicker, jitter and the like of the image projected by the projector, and timely processing the faults of the projector module or the main board when the detection determines that the image projected by the projector is the projector module, so that the use experience of a user on the projector is greatly improved.
Further, based on the above-described first embodiment of the self-inspection method for the cause of abnormality of the projected image of the present invention, a second embodiment of the self-inspection method for the cause of abnormality of the projected image of the present invention is proposed.
In this embodiment, after the step of performing the abnormality processing on the projector module, the method for self-checking the cause of the abnormality of the projected image according to the present invention may further include:
projecting the first standard color image to the projection area again through the projector module;
acquiring an image of the projection area by the RGB camera to obtain third image data containing the first standard color image;
and determining whether the fault of the projector module is eliminated or not according to the third image data, and outputting a preset maintenance recommendation prompt when the fault is determined not to be eliminated.
In this embodiment, after the projector performs exception handling such as firmware upgrading on the projector module with a failure, a self-check process needs to be further performed on the projector module after the exception handling to determine whether the failure of the projector module is effectively eliminated. That is, the projector projects the first standard color image stored in the memory of the projector module to the projection area on the desktop through the projector module after the projector module has undergone the exception processing again, and performs the image acquisition for the preset duration for the projection area through the RGB camera in synchronization, so as to obtain the third image data including the first standard color image again, and finally, further performs the image analysis on the third image data so that the image analysis result obtained by the analysis is: when the third image data does not have the abnormality such as 'abnormal line flicker and jitter', determining that the fault of the projector module has been successfully eliminated, otherwise, if the third image data is subjected to image analysis to obtain an image analysis result after the analysis: if there is an abnormality such as "abnormal line flicker and jitter" in the third image data, it is determined that the malfunction of the projector module has not been eliminated. And under the condition that the projector determines that the fault of the projector module is not eliminated, outputting a preset maintenance recommendation prompt to a user in real time.
It should be noted that, in this embodiment, the preset repair recommendation prompt is a prompt for recommending, to a user, an after-market station near a location where the projector is located, so as to perform inspection and repair on the projector, when it is determined that the projector is damaged by upgrading firmware for the projector module in which a fault occurs but the fault is not eliminated. It should be understood that, based on different design requirements of practical applications, the repair recommendation prompt may of course adopt different contents or output forms in different feasible embodiments, and the method for self-checking the abnormality cause of the projected image according to the present invention is not limited to the specific contents and output forms of the prompt.
In addition, in this embodiment, after the step of "performing exception processing on the main board", the method for self-checking the cause of the exception of the projected image according to the present invention may further include:
projecting the second standard color image to the projection area again through the projector module;
acquiring an image of the projection area through the RGB camera to obtain fourth image data containing the second standard color image;
and determining whether the fault of the main board is eliminated or not according to the fourth image data, and outputting a preset maintenance recommendation prompt when the fault is determined not to be eliminated.
In this embodiment, after performing exception processing such as firmware upgrade on a failed motherboard, the projector further needs to perform a self-test on the motherboard after performing the exception processing to determine whether the failure of the motherboard is effectively eliminated. That is, the projector projects the second standard color image, which is transmitted to the projector module by the main board after the abnormal processing is performed, to the projection area on the desktop through the projector module again, and performs the image acquisition for the preset time length for the projection area through the RGB camera in synchronization, so as to obtain the fourth image data including the second standard color image again, and finally, further performs image analysis on the fourth image data, so that the image analysis result obtained by the analysis is: when the fourth image data does not have the abnormality such as 'abnormal line flicker and jitter', determining that the fault occurring on the main board has been successfully eliminated, otherwise, if the fourth image data is subjected to image analysis so that the image analysis result obtained in the analysis is: if there is an abnormality such as "abnormal line flickering and shaking" in the fourth image data, it is determined that the malfunction of the main board has not been eliminated. And under the condition that the projector determines that the fault of the main board is not eliminated, outputting a preset maintenance recommendation prompt to a user in real time.
It should be noted that, in this embodiment, the preset repair recommendation prompt may also be a prompt for recommending, to the user, an after-market site near the location where the projector is located to check and repair the projector when the projector determines that the motherboard is damaged by upgrading firmware for the failed motherboard without removing the fault.
In this embodiment, after the step of performing the abnormality processing on the projector module or the main board, the method for self-checking the cause of the abnormality of the projected image may further include:
projecting the first standard color image and the second standard color image to the projection area again through the projector module respectively;
acquiring an image of the projection area by the RGB camera to obtain third image data containing the first standard color image and obtain fourth image data containing the second standard color image;
and determining whether the faults of the projector module and the main board are eliminated or not according to the third image data and the fourth image data, and outputting a preset maintenance recommendation prompt when the faults are determined not to be eliminated.
After abnormal processing such as firmware upgrading and the like is carried out on the projector module or the mainboard which has a fault, the projector respectively projects a first standard color image stored in the storage of the projector module to a projection area on the desktop through the projector module again, and projects a second standard color image transmitted to the projector module by the mainboard to the projection area. And in the process of projecting the second standard color image, the RGB camera is synchronously used for carrying out image acquisition with the preset time length on the projection area so as to obtain third image data containing the first standard color image again, and in the process of projecting the second standard color image, the RGB camera is synchronously used for carrying out image acquisition with the preset time length on the projection area so as to obtain fourth image data containing the second color standard image again.
Then, the projector further performs image analysis on the third image data and the fourth image data, and the image analysis result obtained by the analysis is: and when the third image data and the fourth image data do not have the abnormity such as abnormal line flicker and jitter, determining that the fault of the projector module or the mainboard is successfully eliminated. Otherwise, if the image analysis result obtained by performing image analysis on the third image data and the fourth image data is: if there is an abnormality such as "abnormal line flicker and jitter" in the third image data, it is determined that the malfunction of the projector module has not been eliminated; or, if the image analysis result is: if there is an abnormality such as "abnormal line flickering and shaking" in the fourth image data, it is determined that the malfunction of the main board has not been eliminated.
And finally, under the condition that the projector determines that the fault of the projector module or the main board is not eliminated, the projector immediately outputs the maintenance recommendation prompt to the user.
In this embodiment, after the projector performs exception handling such as firmware upgrade on the projector module or the motherboard having a fault, the projector further performs self-checking on both the projector module and the motherboard at the same time to determine whether the fault occurring on the projector module or the motherboard is effectively eliminated. Therefore, the accuracy of detecting whether the faults of the projector module or the mainboard are successfully eliminated is further improved.
Further, a third embodiment of the self-inspection method for the cause of abnormality of the projected image of the present invention is proposed based on the first embodiment and/or the second embodiment of the self-inspection method for the cause of abnormality of the projected image of the present invention described above.
In this embodiment, the projector is internally or externally connected with a server, and the server is connected with a main board of the projector. Based on this, the method for self-checking the abnormality cause of the projection image according to the present invention may further include:

Exemplarily, as shown in the flow of fig. 4, after the projector triggers and generates a projector self-test instruction when the user starts the self-test function, the projector module first projects a first standard color image (including various colors such as red, green, blue, white, and black) stored in the memory of the projector module to the projection area of the desktop, and synchronously performs continuous photographing for 30 seconds on the projection area through the RGB camera, so as to obtain first image data including the first standard color image. Then, the projector further transmits 3 second standard color images (such as the colorful images shown in fig. 5) to the projector module through the motherboard by using the MIPI signal, so that the projector module projects the three images to the projection area on the desktop respectively, and the RGB camera synchronously performs continuous photographing on the projection area for 30 seconds, thereby obtaining second image data including each second standard color image.
Then, the RGB camera transmits the collected first image data back to the server through the main board, and transmits the collected second image data back to the server through the main board, the server performs image analysis on the first image data and the second image data locally respectively after receiving the first image data and the second image data, obtains a detection result of the projector module having a fault under the condition that the first image data is determined to be abnormal but the second image data is normal, and transmits the detection result back to the main board, so that the projector can perform abnormal processing of firmware upgrading on the projector module through the main board, further performs self-check on the projector module again, and outputs the maintenance recommendation prompt to recommend the user that the after-sale point where the projector is located is the nearest to the position of the projector to perform inspection and maintenance when determining that the fault of the projector module has not been eliminated after the self-check again.
Similarly, when the server determines that the second image data is abnormal but the first image data is normal, a detection result indicating that the mainboard has a fault is obtained, and the detection result is transmitted back to the mainboard, so that the projector can perform abnormal processing of firmware upgrading on the mainboard through the mainboard, further perform self-checking on the mainboard again, and output the maintenance recommendation prompt to recommend the user to check and maintain the after-sales point at the nearest position of the projector to the user when the fault of the mainboard is determined to be not eliminated after the self-checking is performed again.
In this embodiment, the method for self-checking the abnormal cause of the projected image according to the present invention detects whether the projector module and the main board have a failure according to the image data by projecting the standard color image by the projector and collecting the image data including the standard color image, so as to automatically detect the cause of the abnormal phenomena such as linear flicker, jitter, etc. in the image projected by the projector, and can timely handle the failure of the projector module or the main board when the failure is detected and determined, thereby greatly improving the user experience of the projector.
