[0028] The present application provides a method for detecting a target object. Figure 2 is a flow chart of a target object detection method according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps: Step S201, obtaining a first video image to be detected corresponding to the bottom space of the vehicle collected by an under-vehicle image detector, performing image detection on the first video image to be detected, and determining whether a first target object is detected in the first video image to be detected, wherein the under-vehicle image detector is installed on the vehicle stop.

[0029] An under-vehicle image detector that can monitor the space below the vehicle is installed. The under-vehicle image detector can be a camera device capable of target recognition, etc. It can be installed on the rear vehicle guardrail corresponding to the parking area, and is used to horizontally shoot the space below the vehicle. The under-vehicle image detector collects scene videos corresponding to the space below the vehicle, and obtains the first video image to be detected therein. The first video image to be detected can be an optical image or an infrared image. Real-time image detection is performed on the first video image to be detected, and it is determined whether a first target object is detected in the first video image to be detected. The first target object can be a child and / or an animal, etc.

[0030] Step S202: When it is detected that a first target object exists in a first video image to be detected, an alarm broadcast instruction is sent to an alarm audio playback module.

[0031] The embodiment of the present application also includes an alarm audio playback module for playing audio, which can be a speaker. When an animal and / or a child is detected in the bottom space of the vehicle, an alarm broadcast instruction is generated and sent to the alarm audio playback module.

[0032] Step S203: In response to the alarm broadcast instruction, the alarm audio playing module plays the alarm audio.

[0033] The alarm audio playback module receives the alarm broadcast command and responds. At the same time, according to the alarm broadcast command content, the module plays the alarm audio, such as a loudspeaker emitting an alarm beep, etc., to remind the driver and other personnel that there is danger under the vehicle and further inspection and processing is required.

[0034] Through the above steps, the embodiment of the present application proposes a method for real-time detection of whether there is a target object under the vehicle, by obtaining the first video image to be detected corresponding to the space under the vehicle collected by the under-vehicle image detector, performing image detection on the first video image to be detected, and judging whether the first target object such as children and / or animals is detected in the first video image to be detected. When the first target object is detected in the first video image to be detected, it indicates that there are children and / or animals under the vehicle, and an accident will occur when the vehicle is started at this time, so an alarm broadcast instruction is sent to the alarm audio playback module; in response to the alarm broadcast instruction, the alarm audio playback module plays the alarm audio to promptly prompt the owner and other personnel to check, so as to remind the target object to leave in time, and the under-vehicle image detector is installed on the parking space and the vehicle barrier, so as to capture real-time video images of the parking area and the space under the vehicle in a more timely manner, thereby solving the problem of how to detect the target object in the space under the vehicle in real time, improving the accuracy and timeliness of target detection, and effectively avoiding the risk of accidents.

[0035] In some embodiments, step S201 includes: Step S2011, obtaining an initial video image to be detected of the target area, and performing image detection on the initial video image to be detected.

[0036] In an embodiment of the present application, when the vehicle has not entered the target area, the under-vehicle image detector is in a dormant state, wherein the target area may be a parking space area. The embodiment of the present application may also include a parking space image detector in addition to the under-vehicle image detector, and the parking space image detector may be a camera device installed on the rear vehicle guardrail corresponding to the parking space area. When the under-vehicle image detector is in a dormant state, the parking space image detector implements acquisition of an initial video image to be detected corresponding to the target area, and performs image detection on the initial video image to be detected. The under-vehicle image detector and the parking space image detector may be arranged independently or integrated together.

[0037] Step S2012: when it is detected that the second target object exists in the initial video image to be detected, the first video image to be detected corresponding to the space under the vehicle is obtained.

[0038] The second target object may be a car tire. When the second target object is detected in the initial video image to be detected, it indicates that a vehicle has entered the parking area. At this time, the under-vehicle image detector is awakened to obtain the first video image to be detected corresponding to the space under the vehicle.

[0039] Step S2013: perform image detection on the first video image to be detected, and determine whether the first target object is detected in the first video image to be detected.

[0040] Furthermore, real-time image detection is performed on the first video image to be detected, and it is determined whether a first target object is detected in the first video image to be detected. The first target object may be a child and / or an animal, etc.

[0041] Through the above steps, the embodiment of the present application monitors the target area where the parking space is located through the parking space image detector. The parking space image detector can be an image detector that consumes less energy than the under-vehicle image detector, so that the under-vehicle image detector remains in a dormant state when the vehicle does not enter, and is awakened when the vehicle enters to obtain the first image to be detected, which has high feasibility and effectively saves resources.

[0042] In some embodiments, step S201 includes: Step S2014, detecting and acquiring a target heat value of the target area, and when the target heat value is greater than a preset heat threshold, acquiring a first video image to be detected corresponding to the bottom space of the vehicle captured by the bottom image detector.

[0043] The embodiment of the present application also includes a heat detector, which can be installed on the car block corresponding to the parking area, and is used to detect the heat value of the target area in real time. The target heat value of the target area collected and obtained is compared with the preset heat threshold. When the vehicle enters the parking area, the heat generated by the engine will increase the heat value of the parking area. In this way, when the target heat value is greater than the preset heat threshold, it is determined that a vehicle has entered the parking area, so the under-vehicle image detector is awakened and the first video image to be detected corresponding to the space under the vehicle is obtained.

[0044] Step S2015: perform image detection on the first video image to be detected, and determine whether the first target object is detected in the first video image to be detected.

[0045] Furthermore, real-time image detection is performed on the first video image to be detected, and it is determined whether a first target object is detected in the first video image to be detected. The first target object may be a child and / or an animal, etc.

[0046] Through the above steps, the embodiment of the present application detects heat in the target area where the parking space is located through a heat detector, determines whether a vehicle enters through the heat changes caused by the engine, and further wakes up the under-vehicle image detector when the vehicle enters, and obtains the first video image to be detected corresponding to the space under the vehicle, which is highly feasible and saves resources.

[0047] In some embodiments, after step S203, the following steps are included: Step S2031: update the first video image to be detected in real time to obtain the second video image to be detected, and perform image detection on the second video image to be detected.

[0048] The first video image to be detected is updated in real time to obtain the second video image to be detected, and image detection is performed on the second video image to be detected. That is, in an embodiment of the present application, when children and / or animals are detected in the first video image to be detected, continuous monitoring and detection will be performed.

[0049] Step S2032, determining the start time of the alarm audio playing module playing the alarm audio as the first time.

[0050] Step S2033: when it is detected that the first target object does not exist in the second video image to be detected within a preset time period after the first moment, the alarm audio playing module stops playing the alarm audio.

[0051] The start time of the alarm audio playback module playing the alarm audio is set as the first moment, and the audio alarm is continuously played from the first moment. Optionally, the audio alarm frequency can be 10 prompts per minute. The alarm duration threshold is pre-set as a preset duration, and optionally, the preset duration can be ten minutes. When it is detected that the first target object does not exist in the second video image to be detected within the preset duration after the first moment, it indicates that the children and / or animals under the vehicle have left within the preset duration, and the danger is eliminated, at which time the alarm audio playback module stops playing the alarm audio.

[0052] Through the above steps, the embodiment of the present application continuously monitors and detects the status of the target object under the vehicle within the preset time period from the start of the alarm through a preset time period. When the target object is driven away within the preset time period, the alarm audio is stopped. This can provide timely feedback on the real-time status of the bottom of the vehicle, avoid false alarms, and has strong adaptability.

[0053] In some embodiments, after step S2032, the method further includes: Step S2132, determining a second moment, where the second moment is the moment corresponding to a preset time period starting from the first moment.

[0054] The time corresponding to the preset time length from the first time is determined as the second time length. Continuing with the above example, when the preset time length is ten minutes, and the alarm audio playback module starts playing the alarm audio at 12:00, then 12:10 is determined as the second time length.

[0055] Step S2232: when it is detected at the second moment that the first target object exists in the second video image to be detected, determine danger warning information, and send the danger warning information to the client device.

[0056] When the first target object is still detected in the second video image to be detected at the second moment, it means that after the preset time, the child and / or animal under the vehicle has not left, and there is still a potential risk. At this time, the danger warning information is determined and sent to the client device.

[0057] Through the above steps, this embodiment sets a preset duration. When the alarm duration exceeds the preset duration, it is detected that the first target object is still present in the second video image to be detected, indicating that children and / or animals have not been driven away for a long time. At this time, the danger alarm information is determined and sent to the client device for further processing by the client user. The alarm range is wide, which can further improve the effectiveness of the alarm and reduce the risk.

[0058] This embodiment also provides a target object detection method. Figure 3 is a flow chart of another target object detection method according to an embodiment of the present application. Figure 3 As shown, the process further includes the following steps based on steps S201 to S203: Step S301, obtaining the area location information of the target area, and sending the area location information to the client device.

[0059] The regional location information of the target area can be the parking space number of the target parking space, and the detectors and speakers on the car barrier are bound to the corresponding parking space number in the parking system viewable by the client device. The regional location information of the target area is obtained and sent to the parking system.

[0060] Step S302: According to the area location information and the danger warning information, the client device displays the user interaction information.

[0061] According to the regional location information, the corresponding parking space of the danger warning information is determined, and the client device displays the user interaction information for further processing by the user. For example, the user interaction information displayed by the client device on the user interaction interface is a selection box, which specifically includes two selection boxes: the danger has been eliminated and the danger has not been eliminated. After the system receives the danger warning information, the parking lot manager checks the alarm parking space area and drives away children and / or animals. After driving away, the parking lot manager selects the selection box of the danger has been eliminated on the user interaction interface, and the corresponding speaker stops playing the warning audio.

[0062] Through the above steps, the embodiment of the present application uses the client's parking system to bind the danger warning information and the parking space number accordingly, and displays the corresponding user interaction information, so that the user can stop the alarm audio in time after manually eliminating the risk, thereby improving the real-time nature of the alarm, avoiding false alarms and saving resources.

[0063] The embodiments of the present application are described and illustrated below through preferred embodiments.

[0064] Figure 4 is a preferred flow chart of the target object detection method according to an embodiment of the present application, such as Figure 4 As shown, the target object detection method includes the following steps: Step S401, detecting and acquiring a target heat value of a target area, and when the target heat value is greater than a preset heat threshold, acquiring a first video image to be detected corresponding to the bottom space of the vehicle collected by a bottom image detector, wherein the bottom image detector is installed on the vehicle guard; Step S402, performing image detection on the first video image to be detected, and determining whether a first target object is detected in the first video image to be detected; Step S403, when it is detected that the first target object exists in the first video image to be detected, sending an alarm broadcast instruction to the alarm audio playback module; Step S404, in response to the alarm broadcast instruction, the alarm audio playing module plays the alarm audio; Step S405, determining the start time of the alarm audio playing module playing the alarm audio as the first time; Step S406: When it is detected that the first target object does not exist in the second video image to be detected within a preset time period after the first moment, the alarm audio playing module stops playing the alarm audio.
