Background Art

[0002] Automation and informatization are the development trends of the world today. With the continuous progress of automation and informatization technology, robotics technology has emerged. Various scientific research institutions and academic units have successively developed various types of industrial robots. As an important research direction in industrial robots, smart cars are increasingly attracting people's attention. Generally speaking, smart cars can automatically complete the tracking function according to the pre-set trajectory. In some complex and harsh environments where humans cannot work normally, smart cars can perform such detection tasks. At present, smart cars are widely used in national defense science and technology, industrial production, warehousing, logistics and other related fields, and have played a huge role.

[0024] The teaching resource sharing platform based on the automotive field of the present application aggregates the teaching resources between various clients. For each client, each client is only allowed to store teaching fragments and each client does not know which part of the teaching resources the teaching fragments it stores belong to. During data transmission, all teaching fragments need to be imported into the platform of the present application and assembled before being sent to the corresponding client that needs the teaching resource for playback, so that each client does not store complete teaching resources, thereby preventing copyright infringement or theft by others.

[0025] In this embodiment, the teaching resource assembly demand module includes: A fragment source database acquisition module, the fragment source database acquisition module is used to acquire a fragment source database, the fragment source database includes at least one complete teaching data and share allocation information corresponding to the teaching data, the share allocation information includes at least one allocation client and the allocation share of the client; A fragment acquisition information acquisition module is used to acquire fragment acquisition information according to the demand information and the fragment source database.

[0026] In this embodiment, the demand information includes at least one required teaching resource to be acquired; The fragment acquisition information acquisition module includes: The share allocation information corresponding to the teaching resources that are the same as the teaching resources to be obtained is obtained respectively.

[0027] In this embodiment, the teaching fragment acquisition module includes: A request module, the request module is used to send request information to the corresponding client according to the share allocation information; The acquisition module is used to acquire the teaching fragments sent in response by each client that receives the request information.

[0028] In this embodiment, the teaching fragment assembly module includes: The acquired teaching fragments are assembled according to the allocated shares of each customer to form teaching resources.

[0029] In this embodiment, the teaching resource sharing platform based on the automobile field further includes: A re-segmentation module is used to re-segment the teaching data that has been sent and update the corresponding share allocation information after the teaching resource sending module sends the assembled teaching resources to the client that requires the teaching resources. Each teaching data is divided into at least two teaching data blocks.

[0030] In this embodiment, the teaching resource sharing platform based on the automobile field further includes: The teaching data segmentation block sending module is used to send the teaching data segmentation blocks to the corresponding clients according to the corresponding updated share allocation information.

[0031] In this embodiment, the teaching data is video stream data, and the teaching data blocks are image data with occlusion. The various teaching data blocks belonging to one image data can form image data without occlusion after being assembled through share allocation information, and the various image data constitute the video stream data according to the share allocation information.

[0032] The present application is further described in detail below by way of examples. It should be understood that the examples do not constitute any limitation to the present application.

[0033] Assuming that there are two teaching videos, it is understandable that there will actually be many teaching videos, hundreds or even thousands.

[0034] Each teaching video is composed of multiple frames of images. It can be understood that for the convenience of description, in this embodiment, the teaching video is composed of only three frames of images (image A, image B, and image C respectively).

[0035] Assume there are 3 clients in total.

[0036] First, each image in the teaching video is segmented. For example, image A can be segmented into three image data with occlusion. The so-called occlusion can be performed by using mosaic to occlude part of the content of image A, or by distorting the pixels. For example, assuming that image A is composed of 3×3 pixels, that is, a total of six pixels (pixel 1, pixel 2, pixel 3, pixel 4, pixel 5, pixel 6), then if image A is segmented into three image data with occlusion, the first occluded image data may occlude pixels 1 and 2, the second occluded image data may occlude pixels 3 and 4, and the third occluded image data may occlude pixels 5 and 6. In other words, these three image data with occlusion are incomplete (the three image data with occlusion are respectively referred to as the first occluded data, the second occluded data, and the third occluded data).

[0037] In this embodiment, after the segmentation and sending are completed, the teaching resource sharing platform based on the automotive field of this application can delete the original data. That is to say, in this case, neither the platform nor each client has the complete video data.

[0038] The remaining image data of the video is also segmented using the above method, which will not be repeated here.

[0039] For example, the first occlusion data is sent to the first client for storage, the second occlusion data is sent to the second client for storage, and the third occlusion data is sent to the third client for storage.

[0040] Assume that when one of the clients, for example, the first client needs to play the video, it sends a request message to the teaching resource sharing platform based on the automotive field. After the teaching resource sharing platform based on the automotive field obtains the request message, it requests the image data transmitted at that time from each client that has the image data through the share allocation information pre-stored during the previous segmentation (for example, the first occluded image data mentioned above occludes pixels 1, 2, 3, and 4, the second occluded image data occludes pixels 3, 4, 5, and 6, and the third occluded image data occludes pixels 1, 2, 5, and 6). After obtaining each image data, since the previous share allocation information is known, the images can be spliced.

[0041] The restored images are then spliced ​​together to form complete video data. It can be understood that the positions of the images relative to each other are also stored in the share allocation information.

[0042] After the complete video data is acquired, the video data can be sent to the required client. After being sent to the required client, the complete video data can be segmented again using the above method.

[0043] The present application also provides a teaching resource sharing method based on the automotive field, and the teaching resource sharing method based on the automotive field includes: Obtaining demand information sent by the client who needs teaching resources; Determine fragment acquisition information according to the acquired demand information and send fragment acquisition requests to each client according to the fragment acquisition information; Acquire teaching fragments provided by different clients according to the fragment acquisition request; Assemble the teaching fragments provided by various clients to form teaching resources; The assembled teaching resources are sent to the client that needs the teaching resources.

[0044] The present application also provides a teaching resource sharing system based on the automobile field, which includes a teaching resource sharing platform based on the automobile field and multiple clients. The teaching resource sharing platform based on the automobile field cooperates with each of the clients to implement the teaching resource sharing platform based on the automobile field as described above.

[0045] Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto based on the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection claimed by the present invention.
