For example, the video images include a video image 1, a video image 2 and a video image 3, the video image 1 carries a positioning barcode a, the video image 2 carries a positioning barcode b, and the video image 3 carries a positioning barcode c, and then the positioning barcode a, the positioning barcode b and the positioning barcode c are different from each other. In addition, the monitoring video at least comprises one video image without continuous video images, in other words, the plurality of video images at least comprises a first video image, the plurality of video images do not have second video images, the first video image and the second video image are not continuous video images, namely, any second video image except the first video image in the plurality of video images is not continuous with the first video image. In one implementation manner of this embodiment, the monitoring video may be configured with a video identifier, and a target object corresponding to the monitoring video may be determined according to the video identifier, so when the monitoring video of the target object is obtained, the monitoring video corresponding to the target object may be selected according to a corresponding relationship between the target object and the video identifier.
The target video image is a video image of a target object when an accident occurs, wherein the target video image can be determined based on a selection instruction.

In addition, the positioning bar code can also comprise task names (such as grain bearing, grain inspection and the like) corresponding to the positions of the acquisition equipment. In one implementation of this embodiment, the positioning barcode may be disposed at any position of the video image, for example, the upper left corner, the upper right corner, the lower left corner, etc.; and the positioning information can be obtained by scanning the positioning bar code, or the positioning information corresponding to the positioning bar code is transferred by clicking the positioning bar code, so that the positioning information is displayed on a display interface for displaying video images, and the like.
In one implementation manner of the embodiment, the generation process of the monitoring video specifically includes:
acquiring a moving track corresponding to a target object, and determining each acquisition device corresponding to the moving track;
acquiring reference monitoring videos acquired by each acquisition device;
and selecting a plurality of reference video images from each reference monitoring video, and configuring corresponding positioning bar codes for each selected reference video image to obtain the monitoring video corresponding to the target object.
Specifically, the target object may be grain, and the moving track of the target object is a moving track of a transport means for transporting the target object. For example, the target object is corn, the conveyance is a truck, and the trajectory is the movement of the truck to load the corn from entering the factory floor gate to transporting the corn to the warehouse. In this embodiment, each collection device corresponding to the moving track refers to a collection device disposed on the moving track, where each collection device may be disposed on the moving track at intervals, or may be disposed at a plurality of designated positions in the moving track, respectively.
The reference surveillance video is a surveillance video adopted by the acquisition device, and the reference surveillance video comprises a target object. The reference monitoring video may be a monitoring video acquired when the target object passes through the acquisition range of the acquisition device, so as to record the whole process of the target object passing through the acquisition range of the acquisition device. In one implementation of this embodiment, the reference surveillance video includes a plurality of consecutive reference video images, and each of the plurality of reference video images includes a target object, and the plurality of reference video images includes a video image of an entry time at which the target object enters the acquisition range of the acquisition device, and a video image of an exit time at which the target object leaves the acquisition range of the acquisition device, in other words, the plurality of reference video images includes a first reference video image and a second reference video image, the acquisition time of the first reference video image being an entry time at which the target object enters the acquisition range of the acquisition device, and the acquisition time of the second reference video image being an exit time at which the target object leaves the acquisition range of the acquisition device.

and splicing the video segments corresponding to the reference monitoring videos according to the running track to obtain the monitoring video corresponding to the target object.
Specifically, each of the plurality of reference video images is included in the reference monitor video, and the plurality of reference video images includes fewer images than the reference monitor video. In other words, the plurality of reference video images are part of the video images of the reference monitor video terminal, and the plurality of reference video images can be obtained by capturing one reference video image at each preset time interval.
In addition, the preset time corresponding to each of the plurality of reference monitoring videos may be the same, for example, 1s,2s, etc., or the preset time corresponding to each of the plurality of reference monitoring videos is different, and the number of the reference video images selected in a manner of spacing the preset time is the same, or the preset time may be determined according to the video duration of the reference monitoring video, and the larger the video duration is, the longer the preset time corresponding to the reference monitoring video is; on the contrary, the smaller the video duration is, the shorter the preset time corresponding to the reference monitoring video is, so that not only a plurality of reference video images of each reference monitoring video can be captured, but also the problem that the number of the reference video images captured by the long reference monitoring video is too large and the number of the monitoring video including video images is too large, which causes the waste of storage space and viewing time, and meanwhile, for the reference video images with the short video duration, the problem that the number of the images of the captured reference video images is too small and accidents cannot be accurately positioned due to the fact that the number of the images of the captured reference video images is too small can be avoided by shortening the preset time corresponding to the video.

Of course, when the positioning bar code is generated, the task name of the acquisition device corresponding to each reference monitoring video may be acquired, and the task name may be added to the positioning bar code. In addition, it should be noted that other positioning information may be included in the positioning bar code, which is not described herein.
Further, after configuring the corresponding positioning bar codes for the selected reference video images, the reference video images are spliced according to the acquisition time to obtain the video segments. After the video segments corresponding to the reference monitoring videos are obtained, splicing the video segments according to the sequence of the acquisition equipment corresponding to the reference monitoring videos on the running track so as to enable the monitoring videos corresponding to the target objects. Therefore, in the monitoring video corresponding to the target object, the running sequence of the target object on the running track is the same as the playing sequence of the monitoring video, for example, the running track comprises a track point A and a track point B, the track point A corresponds to the video segment a, the track point B corresponds to the video segment B, the target object passes through the track point A and then passes through the track point B, and then the video segment a is played in the monitoring video, and the video segment B is played.
In one implementation manner of this embodiment, after selecting a plurality of reference video images from each reference monitoring video, and configuring a corresponding positioning barcode for each selected reference video image to obtain a monitoring video corresponding to a target object, the method further includes:
and storing the reference monitoring video acquired by each acquisition device in the monitoring video and the running track.
Specifically, the reference monitoring videos acquired by each acquisition device in the running track are stored in the storage device corresponding to the acquisition device according to the corresponding automatic updating process of the acquisition device, and are automatically updated and cleared, for example, the storage time of the reference monitoring videos is a preset time length, and the reference monitoring videos are automatically deleted after the preset time length is reached, or the reference monitoring videos with early storage time are automatically deleted according to the storage time when the storage space of the storage device is full. The monitoring video corresponding to the target object can be stored in the backup storage device, and the monitoring video corresponding to the target object can be stored for a long time and can be deleted only after receiving a deleting instruction input by a user. In other words, the monitoring video corresponding to the target object and the reference monitoring video acquired by each acquisition device are stored separately, so that each reference monitoring video can be quickly positioned through the monitoring video corresponding to the target object in a short time, the positioning speed of the reference monitoring video is improved, only the monitoring video corresponding to the target object can be included in a long time, each reference monitoring video does not need to be stored, the storage space stored for a long time can be saved, and meanwhile, the accident occurrence time and the accident occurrence place can be primarily determined based on the monitoring video corresponding to the target object.
S20, determining accident positioning information of the target object based on the positioning bar code in the target video image.
Specifically, the accident positioning information of the target object is used to reflect accident information of the target object in which an accident (e.g., loss, damage, etc.) occurs, wherein the accident information may include accident position information, time information, etc. The accident positioning information can be determined based on positioning information included in the positioning bar code, for example, the positioning bar code includes video acquisition time and acquisition equipment information, the accident occurrence time can be positioned according to the video acquisition time, the acquisition equipment for acquiring the target video image can be determined according to the acquisition equipment information, the accident occurrence position can be determined according to the setting position of the acquisition equipment, and the like.
