The specification provides a vehicle image acquisition guiding method, and also provides a vehicle image acquisition guiding device, a computing device and a computer readable storage medium. The following detailed description and the explanation of the steps of the method are individually made with reference to the drawings of the embodiments provided in the present specification.

The embodiment of the vehicle image acquisition guiding method provided by the specification is as follows:

Step S102, extracting a first image frame from a video stream acquired by an acquisition terminal aiming at a target vehicle.

In practical application, a vehicle owner needs to comprehensively detect and evaluate the vehicle condition of a vehicle in the process of purchasing a vehicle insurance from the vehicle, and needs to acquire the image of the vehicle in the process of evaluating the vehicle condition of the vehicle, and evaluate the vehicle condition on the basis of the acquired image of the vehicle so as to purchase insurance.

The vehicle image acquisition guiding method provided by the embodiment comprises the steps of carrying out image acquisition on a target vehicle in a video acquisition mode, controlling the acquisition quality of image acquisition on the target vehicle by detecting whether acquired image frames contain the acquisition identification of the target vehicle or not in the acquisition process, prompting the acquisition sequence of an acquisition terminal on the vehicle part of the target vehicle on the basis of identifying the vehicle part contained in the image frames, detecting and prompting the image acquisition process of the vehicle, on one hand, improving the quality of the acquired image, on the other hand, improving the acquisition efficiency of image acquisition on the target vehicle, and improving the experience of the image acquisition process.

The target vehicle in this embodiment is a vehicle that needs to perform image acquisition, for example, an owner of the vehicle needs to purchase a vehicle insurance for a vehicle C under its own name, the vehicle condition of the vehicle C needs to be detected and evaluated in detail in the insurance purchasing process, and the detection and evaluation of the vehicle condition need to be performed on the basis of the acquired image of the vehicle C, so that the vehicle C is the target vehicle that performs image acquisition, and then the vehicle condition of the vehicle C is determined according to the image (or video) acquired for the vehicle C in the insurance application process, and the vehicle C is subjected to insurance application processing based on the image (or video).

The acquisition terminal in this embodiment refers to a terminal device that acquires an image of a target vehicle, and the acquisition terminal may be a mobile terminal equipped with an image acquisition component, or may be another image acquisition terminal device that is used for acquiring an image, which is not limited to this.

In this embodiment, in the process of capturing an image of a target vehicle by using the capture terminal, the capture is performed in a video capture mode, so that the captured data also exists in the form of a video stream, and in the process of guiding image capture of the target vehicle, the capture is performed on the basis of extracting an image frame from the video stream. It should be noted that, in the present embodiment, the image of the target vehicle is captured by the capture terminal in a video capture manner, and the image capture process of the target vehicle in the video capture manner is continuous until all the images of the target vehicle are captured.

In this embodiment, the first image frame is extracted from the video stream captured by the capture terminal for the target vehicle, and the purpose of extracting the first image frame is to detect whether image capture performed by the capture terminal on the target vehicle meets the image capture requirement (i.e., the detection process of the first image frame in step S104 described below), where the detection process is to ensure that the image captured for the target vehicle meets the image capture requirement. The method includes the steps that a first image frame extracted from a video stream collected by a collection terminal for a target vehicle is not an image frame extracted from the video stream, but an image frame extracted from the video stream at a certain time interval, for example, an image frame is extracted from the video stream collected by the collection terminal for the target vehicle at intervals of 2S or 5S and is used as a first image frame for detecting whether an image collection requirement is met; or, under the condition that the image processing capability and the computing resource allow, each image frame in the video stream acquired by the acquisition terminal for the target vehicle can be extracted as a first image frame for detecting whether the image acquisition requirement is met, so that the image frames contained in the video stream acquired by the acquisition terminal for the target vehicle are all ensured to meet the image acquisition requirement.

Step S104, detecting whether the first image frame has the acquisition identifier of the target vehicle in the image frame area corresponding to the reference acquisition range.

After the first image frame is extracted from a video stream acquired by an acquisition terminal for a target vehicle, the extracted first image frame is detected, and whether the extracted first image frame meets an image acquisition requirement is detected, specifically, whether an acquisition identifier of the target vehicle exists in an image frame area corresponding to a reference acquisition range is detected.

The purpose of setting the reference capture range in the embodiment is to constrain the image capture process of the target vehicle, and improve the quality of the image frames included in the video stream captured for the target vehicle, and the integrity and usability of the image features of the target vehicle included in the image frames.

The reference acquisition range refers to acquisition requirements or limitations of the acquired image characteristics of the target vehicle in the process of acquiring the image of the target vehicle by using the acquisition terminal. As shown in fig. 2 and fig. 3, the image capture pages are displayed on the capture terminal, where 201 is a reference capture range set in the image capture page, and based on the reference capture range, in the process of capturing an image of the vehicle C, the target is to capture an image of the vehicle C around the vehicle body, that is, to capture images of vehicle positions of the vehicle C around the vehicle body within the reference capture range.

In an optional implementation manner provided by this embodiment, on the basis that the first image frame is extracted from a video stream captured by a capture terminal for a target vehicle in the above step, and before detecting whether a capture identifier of the target vehicle exists in an image frame region corresponding to a reference capture range of the first image frame, a vehicle part of the target vehicle included in the first image frame is first identified;

optionally, the vehicle part corresponding to the collection identifier includes at least one of the following: a vehicle top portion and a vehicle bottom portion; a vehicle top part 202 and a vehicle bottom part 203 provided by an image capture page displayed on a mobile phone screen serving as a capture terminal shown in fig. 2, a vehicle top part 302 and a vehicle bottom part 303 provided by an image capture page displayed on a mobile phone screen serving as a capture terminal shown in fig. 3;

further, whether a vehicle part corresponding to the acquisition identifier exists in the vehicle parts of the target vehicle contained in the first image frame is judged;

if the first image frame is acquired, the acquired first image frame is shown to contain the vehicle top part and the vehicle bottom part of the target vehicle, then an acquisition identification process for detecting whether the first image frame has the target vehicle in an image frame area corresponding to a reference acquisition range is executed, and the first image frame contained in a video stream acquired by an acquisition terminal is further detected;

if not, it is indicated that the acquired first image frame does not include the vehicle top part and the vehicle bottom part of the target vehicle, a prompt for acquisition adjustment is sent to the acquisition terminal, for example, a prompt for displaying an image acquisition angle or an image acquisition distance on an image acquisition page of the acquisition terminal is sent to remind an operator of the acquisition terminal of bringing the vehicle top part and the vehicle bottom part of the target vehicle into an acquisition target of a reference acquisition range of the image acquisition page of the acquisition terminal by adjusting the acquisition angle or the acquisition distance between the acquisition terminal and the target vehicle.

In specific implementation, on the basis that the vehicle part corresponding to the acquisition identifier includes a vehicle top part and a vehicle bottom part, detecting whether the acquisition identifier of the target vehicle exists in an image frame region corresponding to a reference acquisition range of the first image frame, that is, detecting whether the vehicle top part and the vehicle bottom part of the target vehicle exist in the image frame region corresponding to the reference acquisition range of the first image frame;

if yes, it is indicated that the image frame area corresponding to the reference acquisition range in the acquired first image frame includes a vehicle top part and a vehicle bottom part of a target vehicle, optionally, the vehicle part of the target vehicle corresponding to the first image frame is identified, and an acquisition guidance prompt for acquiring a next vehicle part of the target vehicle is sent to the acquisition terminal based on the vehicle part acquisition sequence;

if not, the acquired first image frame does not include the vehicle top part and the vehicle bottom part of the target vehicle in the image frame region corresponding to the reference acquisition range, and the following step S106 is executed to send a prompt for acquisition adjustment to the acquisition terminal.

For example, as shown in fig. 2, the mobile phone serves as an image capture page of the capture terminal, and an image displayed on the image capture page is an image frame extracted from a video stream captured by the mobile phone for the vehicle C; as can be seen, the extracted vehicle bottom portion 203 of the vehicle C in the image frame is within the reference collection range of the image collection page, and the vehicle top portion 202 of the vehicle C is not within the reference collection range of the image collection page and exceeds the reference collection range of the image collection page, so that a reminder for collection adjustment needs to be sent out on the image collection page of the mobile phone, for example, the reminder that "the adjustment of the angle of the mobile phone is required to keep the vehicle top portion in the screen" shown in fig. 2 reminds the operator who performs image collection on the vehicle C to adjust the collection angle of the mobile phone, and brings the vehicle top portion 202 and the vehicle bottom portion 203 of the vehicle C into the reference collection range of the image collection page, so as to collect the vehicle image meeting the image collection requirement.

And step S106, sending a prompt for acquisition adjustment to the acquisition terminal.

If the step S104 detects that the first image frame has the acquisition identifier of the target vehicle in the image frame region corresponding to the reference acquisition range, that is, if the acquired first image frame does not include the vehicle top part and the vehicle bottom part of the target vehicle in the image frame region corresponding to the reference acquisition range, the step is executed to send a prompt to the acquisition terminal to perform acquisition adjustment.

On the basis of the optional implementation manner provided in the step S104, here, sending a reminder to perform acquisition adjustment to the acquisition terminal is implemented by adopting the following optional implementation manner:

In practical application, if the first image frame acquired by the acquisition terminal does not have the vehicle top part corresponding to the acquisition identifier in the image frame region corresponding to the reference acquisition range, it indicates that the vehicle top part of the target vehicle exceeds the image acquisition limit above the reference acquisition range, and at this time, the operation direction of the acquisition terminal should be prompted to move the acquisition view angle of the acquisition terminal upwards, so that the acquisition terminal can acquire the vehicle top part and the vehicle bottom part of the target vehicle in the reference acquisition range after adjustment;

similarly, if the first image frame acquired by the acquisition terminal does not have the vehicle bottom part corresponding to the acquisition identifier in the image frame region corresponding to the reference acquisition range, it indicates that the vehicle bottom part of the target vehicle exceeds the image acquisition limit below the reference acquisition range, and at this time, the operation party of the acquisition terminal should be prompted to move the acquisition view angle of the acquisition terminal downwards, so that the acquisition terminal can acquire the vehicle bottom part and the vehicle top part of the target vehicle in the reference acquisition range after adjustment;

therefore, the reminding of acquisition adjustment is sent to the acquisition terminal through the two types of information, the condition that the top part and the bottom part of the vehicle of the target vehicle exceed the reference acquisition range is pointed, the reminding information and the reminding identification of the adjustment of the image acquisition visual angle are displayed on the image acquisition page of the acquisition terminal, and the reminding information and the reminding identification are matched, so that the reminding of the adjustment of the image acquisition visual angle is sent to the acquisition terminal more visually and more effectively, and meanwhile, the humanization degree of the reminding sent in the image acquisition process of the target vehicle is also improved.

For example, in the image capturing page of the capturing terminal shown in fig. 2, the displayed image is an image frame extracted from a video stream captured by the mobile phone for the vehicle C, where the vehicle bottom portion 203 of the vehicle C in the image frame is within the reference capturing range of the image capturing page, and the vehicle top portion 202 of the vehicle C is not within the reference capturing range of the image capturing page and has exceeded the reference capturing range of the image capturing page, so that a prompt for performing capturing adjustment needs to be sent on the image capturing page of the mobile phone, for example, a prompt of "asking for adjusting the angle of the mobile phone to keep the vehicle top portion in the screen" shown in fig. 2 is displayed on the image capturing page of the mobile phone, and a prompt identifier of "upward arrow" for prompting the operating direction to move the capturing angle of the mobile phone upward is displayed on the upper position of the reference capturing range of the image capturing page, and the capturing angle of the mobile phone is adjusted more accurately by combining the two prompts, so that the vehicle top portion 202 and the vehicle bottom portion 203 of the vehicle C are brought into the reference capturing range of the image capturing page, and the vehicle image meeting the image capturing requirement is captured.

Step S108, under the condition that the second image frame extracted from the video stream acquired by the acquisition terminal after the acquisition adjustment has the acquisition identifier in the image frame area corresponding to the reference acquisition range, the vehicle part of the target vehicle corresponding to the second image frame is identified.

As described above, the process of image acquisition by the acquisition terminal for the target vehicle is performed in a video acquisition manner, and the video acquisition process is continuous, and the video acquisition process of the acquisition terminal for the target vehicle is not interrupted by sending a reminder for acquisition adjustment or an acquisition guidance prompt described below, so that it can be seen that there is only one video stream acquired by the acquisition terminal for the target vehicle. It should be noted that, the first image frame extracted from the video stream acquired by the acquisition terminal, the second image frame extracted from the video stream acquired by the acquisition terminal in this step, and the third image frame or even the nth image frame extracted from the video stream acquired by the acquisition terminal in the following step, where the video streams for extracting the image frames all refer to the video streams acquired by the acquisition terminal for the target vehicle, and the first image frame, the second image frame, the third image frame or even the nth image frame are extracted from the video streams acquired by the acquisition terminal, and there is no essential difference between the image frames, and the difference is only that:

the image frames extracted from the video stream are processed differently at different stages of image acquisition for the target vehicle, and therefore, for convenience of description and distinction of the different processing stages, the image frames extracted from the same video stream are named the first image frame, the second image frame, the third image frame, and even the nth image frame.

In an optional implementation manner provided in this embodiment, when a second image frame extracted from a video stream acquired by an acquisition terminal after acquisition adjustment has the acquisition identifier in an image frame region corresponding to the reference acquisition range, the vehicle part of the target vehicle corresponding to the second image frame is identified, which is specifically implemented by the following method:

detecting whether the second image frame has the acquisition identifier in an image frame region corresponding to the reference acquisition range; wherein the acquisition identifier comprises a vehicle top part and a vehicle bottom part;

if yes, the second image frame is extracted from the video stream acquired by the acquisition terminal after acquisition adjustment, wherein the second image frame comprises the vehicle top part and the vehicle bottom part of the target vehicle, and the vehicle part of the target vehicle corresponding to the second image frame is identified;

if not, indicating that the vehicle top part or the vehicle bottom part of the target vehicle is not included in the second image frame extracted from the video stream acquired by the acquisition terminal after acquisition adjustment, and sending a prompt for acquisition adjustment to the acquisition terminal.

Specifically, if the first image frame does not have the vehicle top part corresponding to the acquisition identifier in the image frame region corresponding to the reference acquisition range, displaying a reminding message and a reminding identifier for adjusting the image acquisition visual angle upwards on the basis of an image acquisition page of the acquisition terminal;

similarly, if the vehicle bottom part corresponding to the acquisition identifier does not exist in the image frame region corresponding to the reference acquisition range of the first image frame, displaying the reminding information and the reminding identifier for adjusting the image acquisition visual angle downwards based on the image acquisition page of the acquisition terminal.

In the above example, in the image capturing page using the mobile phone shown in fig. 2 as the capturing terminal, the displayed image is an image frame extracted from a video stream captured by the mobile phone for the vehicle C, the vehicle bottom portion 203 of the vehicle C in the image frame is within the reference capturing range of the image capturing page, and the vehicle top portion 202 of the vehicle C is not within the reference capturing range of the image capturing page and exceeds the reference capturing range of the image capturing page, so that a prompt for performing capturing adjustment needs to be sent out on the image capturing page of the mobile phone, for example, a prompt of "requiring to adjust the angle of the mobile phone to keep the vehicle top portion within the screen" shown in fig. 2 is displayed on the image capturing page, and a prompt identifier of "upward arrow" for prompting the operating party to move the capturing angle of the mobile phone upward is displayed on the upper position of the reference capturing range of the image capturing page, and the operating party is prompted to adjust the capturing angle of the mobile phone by a combination of the two prompts;

thereafter, after the acquisition angle of the mobile phone is adjusted according to the prompt, the video acquisition mode is continuously adopted to acquire the image of the vehicle C, the image frames extracted from the adjusted video stream are displayed on the image acquisition page of the mobile phone, as shown in fig. 3, and both the vehicle top part 302 and the vehicle bottom part 303 of the vehicle C in the image frames are within the reference acquisition range of the image acquisition page of the mobile phone.

During specific implementation, in order to improve the acquisition efficiency and acquisition accuracy rate of image acquisition for a target vehicle, a vehicle part acquisition sequence is set in the image acquisition process for the target vehicle, and the acquisition sequence of the target vehicle and the vehicle part are constrained based on the set vehicle part acquisition sequence, so that the acquisition terminal is more accurate for the image acquired by the target vehicle on the basis of the vehicle part acquisition sequence.

Specifically, in an optional implementation manner provided in this embodiment, when the second image frame extracted from the video stream acquired by the acquisition terminal after the acquisition adjustment exists in the image frame region corresponding to the reference acquisition range and the acquisition identifier is identified, the following operations are performed after the second image frame is identified as corresponding to the vehicle part of the target vehicle:

if the second image frame extracted after the acquisition adjustment is consistent with the reference vehicle part to be acquired specified by the vehicle part acquisition sequence, the second image frame is extracted, and the vehicle part acquired by the target vehicle is consistent with the reference vehicle part to be acquired, the successful acquisition reminding mark of the reference vehicle part is displayed based on the image acquisition page of the acquisition terminal, and the following step S110 is executed, and the acquisition guiding prompt for acquiring the next vehicle part of the target vehicle is sent to the acquisition terminal based on the preset vehicle part acquisition sequence;

if the acquired vehicle parts are inconsistent, the acquired vehicle parts of the second image frames extracted after the acquisition adjustment are inconsistent with the reference vehicle parts to be acquired according to the vehicle part acquisition sequence, namely the acquired vehicle parts are failed to be acquired according to the vehicle part acquisition sequence, and a failure reminding identifier of the reference vehicle part acquisition failure is displayed on the basis of an image acquisition page of the acquisition terminal.

For example, the starting vehicle part for vehicle acquisition recorded in the vehicle part acquisition sequence is "head", and then the following parts of the vehicle are sequentially acquired in a clockwise surrounding manner from the vehicle part of "head": "front head" - > "left front headlight" - > "left front body" - > "left rear view mirror" - > "left front door" - > "left rear headlight" - > "left rear wing" - > "right rear headlight" - > "right rear door" - > "right front door" - > "right rear view mirror" - > "right front body" - > "right front headlight" - >;

after the acquisition angle of the mobile phone is adjusted, the image frame extracted from the video stream acquired by the mobile phone is as shown in fig. 3, it can be seen that both the vehicle top portion 302 and the vehicle bottom portion 303 of the vehicle C in the image frame are within the reference acquisition range of the image acquisition page of the mobile phone, and the image frame is input into a vehicle portion identification model trained in advance to perform vehicle portion identification, and the vehicle portion of the vehicle C corresponding to the image frame is output as a "head";

further, whether a vehicle part, namely a vehicle head collected by the mobile phone aiming at the vehicle C, is consistent with a vehicle part recorded in a vehicle part collecting sequence is judged, specifically, the vehicle part collected first in the vehicle part collecting sequence is the vehicle head, and is consistent with the vehicle part currently collected by the mobile phone for the vehicle C, so that the vehicle part collecting sequence is consistent with the vehicle part collecting sequence, the name of the vehicle part, namely the vehicle head collected currently, and a successful reminding mark for successful collection are displayed at the upper right corner of a reference collecting range of an image collecting page of the mobile phone, and the successful reminding mark is a mark in a shape of a small circle point;

in addition, if the vehicle parts acquired by the mobile phone do not accord with the vehicle part acquisition sequence, the names of the vehicle parts with failed acquisition and failed acquisition reminding identifications recorded in the vehicle part acquisition sequence are displayed at the upper right corner of the reference acquisition range of the image acquisition page, and the failed reminding identifications can be X-shaped identifications.

And step S110, sending a collection guidance prompt for collecting the next vehicle part of the target vehicle to the collection terminal based on a preset vehicle part collection sequence.

In an optional implementation manner provided in this embodiment, based on a preset vehicle location acquisition sequence, an acquisition guidance prompt for acquiring a next vehicle location of the target vehicle is sent to the acquisition terminal, and the following implementation manner is specifically adopted:

1) Determining that the acquisition terminal acquires a next vehicle part of the target vehicle based on the vehicle part acquisition sequence;

2) Determining an acquisition movement direction from the second image frame corresponding to the vehicle location of the target vehicle to the next vehicle location based on the determined next vehicle location and the second image frame corresponding to the vehicle location of the target vehicle;

3) And displaying the acquisition guiding prompt acquired according to the acquisition moving direction on the basis of an image acquisition page of the acquisition terminal.

Starting from the vehicle position of the target vehicle corresponding to the second image frame and the next vehicle position determined based on the vehicle position acquisition sequence, the acquisition moving direction from the vehicle position corresponding to the second image frame to the next vehicle position is determined, that is, the acquisition moving direction from the vehicle position corresponding to the acquired second image frame to the next vehicle position in the acquisition process of the acquisition terminal is determined, and the acquisition guidance prompt for acquiring according to the acquisition direction is displayed on the image acquisition page of the acquisition terminal, so that the acquisition terminal is guided to acquire the image of the target vehicle more accurately, more efficiently and more specifically through the intuitive acquisition guidance prompt.

Still taking the car-surrounding image acquisition of the vehicle C by the mobile phone as an example, after the acquisition angle of the mobile phone is adjusted, the image frame extracted from the video stream acquired by the mobile phone is as shown in fig. 3, as can be seen, the vehicle top part 302 and the vehicle bottom part 303 of the vehicle C in the image frame are both located in the reference acquisition range of the image acquisition page of the mobile phone, and the vehicle part is identified by inputting the image frame into a pre-trained vehicle part identification model, and outputting the vehicle part of the vehicle C corresponding to the image frame as the "head";

after the vehicle part of the head is successfully acquired, determining the next vehicle part of the head as a vehicle part of a left headlamp according to the acquisition sequence of the vehicle parts recorded in the acquisition sequence of the vehicle parts;

secondly, according to the vehicle part of the 'head' and the next vehicle part of the 'left headlight' which are collected by the vehicle C, the collection moving direction from the vehicle part of the 'head' to the next vehicle part of the 'left headlight' is determined to move leftwards, namely: in the process of acquiring the image of the vehicle C in a video acquisition mode, if the vehicle parts of the vehicle C are required to be sequentially acquired according to the vehicle part acquisition sequence, the mobile phone which serves as an acquisition terminal for acquiring the image of the vehicle C needs to move leftwards to move from the acquired vehicle part, namely the head of the vehicle, to the next vehicle part, namely a left headlamp, for acquisition;

and finally, displaying an acquisition guiding prompt which is acquired according to the leftward movement acquisition moving direction on an image acquisition page of the mobile phone, wherein the acquisition guiding prompt comprises two parts, the first part is a text prompt of 'please move the car around to the left headlamp direction' displayed in the middle of a reference acquisition range of the image acquisition page, the second part is a graphic prompt of 'left arrow' displayed below the text prompt, and the visual and accurate prompt is performed in a mode of combining the text prompt and the graphic prompt, so that the mobile phone serving as the role of an acquisition terminal is guided to acquire the car-around image of the vehicle C more accurately and more efficiently.

In addition, in a specific implementation, in order to improve the integrity of image acquisition performed by the acquisition terminal on the target vehicle, and detect whether the image acquisition performed on the target vehicle reaches the target through a detection mechanism, and meanwhile, in order to ensure the integrity of the image acquired on the target vehicle, in an optional implementation manner provided in this embodiment, after sending an acquisition guidance prompt for acquiring the next vehicle location to the acquisition terminal based on the vehicle location acquisition sequence, the following operations are performed:

1) Extracting a third image frame from a video stream acquired by the acquisition terminal aiming at a next vehicle part of the target vehicle;

2) Detecting whether the third image frame has the acquisition identifier in an image frame region corresponding to the reference acquisition range; the vehicle parts corresponding to the acquisition marks comprise a vehicle top part and a vehicle bottom part;

if yes, indicating that the acquired third image frame comprises the vehicle top part and the vehicle bottom part of the target vehicle, and executing step 3);

if the third image frame does not exist, the third image frame is acquired, and the vehicle top part and the vehicle bottom part of the target vehicle are not included, a prompt for acquisition adjustment is sent to the acquisition terminal, for example, a prompt for displaying an image acquisition angle or an image acquisition distance on an image acquisition page of the acquisition terminal is sent, so that an operator of the acquisition terminal is reminded to bring the vehicle top part and the vehicle bottom part of the target vehicle into a reference acquisition range of the image acquisition page of the acquisition terminal by adjusting the acquisition angle or the acquisition distance between the acquisition terminal and the target vehicle;

3) Identifying the next vehicle part corresponding to the third image frame;

4) Judging whether the next vehicle part corresponding to the third image frame is consistent with a reference vehicle part determined according to the vehicle part acquisition sequence;

if the vehicle parts are consistent with the reference vehicle parts, the vehicle parts included in the third image frame collected by the target vehicle are consistent with the collected reference vehicle parts specified by the vehicle part collecting sequence, and step 5) is executed;

if the acquired vehicle parts are inconsistent, the acquired vehicle parts contained in the third image frame acquired by the target vehicle are inconsistent with the acquired reference vehicle parts specified by the vehicle part acquisition sequence, namely the acquired vehicle parts specified by the vehicle part acquisition sequence fail to be acquired, and displaying a failure reminding identifier of the reference vehicle part acquisition failure on the basis of an image acquisition page of an acquisition terminal;

5) Judging whether the next vehicle part corresponding to the third image frame is the last vehicle part determined according to the vehicle part acquisition sequence;

if so, storing the video streams acquired by the acquisition terminal aiming at each vehicle part of the target vehicle in a video file form;

if not, returning to execute the preset vehicle part acquisition sequence, sending an acquisition guidance prompt step for acquiring the next vehicle part of the target vehicle to the acquisition terminal, and repeating the process of sending the acquisition guidance prompt of the next vehicle part- > acquiring the next vehicle part and detecting according to the acquisition guidance prompt until all vehicle parts of the target vehicle are acquired according to the vehicle part acquisition sequence.

For example, in the process that the mobile phone captures the vehicle C in a video capturing manner, when the image frame extracted from the captured video stream includes a vehicle top portion and a vehicle bottom portion of the vehicle C, the vehicle portion of the vehicle C corresponding to the image frame is identified as a "right front headlight", the vehicle portion coincides with a vehicle portion capturing sequence, and the vehicle portion of the "right front headlight" can be determined as a last vehicle portion to be captured recorded in the vehicle portion capturing sequence according to the vehicle portion capturing sequence, which indicates that the mobile phone has finished capturing the ring vehicle image of the vehicle C as the capturing terminal, and the video streams captured by the mobile phone in the video capturing manner for all vehicle components (from the "head" of the first vehicle component to the "right front headlight" of the last vehicle portion) of the vehicle C are stored in the form of a video file.

In summary, the vehicle image collection guiding method starts from a video stream collected by a collection terminal for a target vehicle, detects whether a collected image meets an image detection requirement by detecting whether the collected image frame includes a collection identifier of the target vehicle, and further prompts a collection sequence of the collection terminal for the vehicle parts of the target vehicle on the basis of identifying the vehicle parts included in the image frame and sends a collection guiding prompt for collecting the image according to the collection sequence of the vehicle parts to the collection terminal under the condition that the image frame extracted from the collected video stream meets the image detection requirement, so that on one hand, the quality of image collection is improved, on the other hand, the collection efficiency of image collection for the target vehicle is also improved, and the experience of the image collection process is improved.
