[0028] First, see Figure 1 , Figure 1 1 is a schematic diagram of the right side structure of a helmet according to some embodiments of the present disclosure for installing a battery box.

[0030] As an example, Figure 2 shown. Figure 2 2 shows a schematic diagram of the structure of the elastic buckle 2. At least one set of symmetrical protrusions can be provided on two sides of the elastic buckle 2 to be embedded in the vent hole of the helmet shell 1. For example, the thickness of the elastic buckle can be 2.5 mm.

[0031] In practice, without destroying the existing structure of the helmet, the existing vent hole is used as a card slot and the elastic characteristics of the plastic part are used to make a retractable elastic wall stuck in the vent hole.

[0046] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: through the safety helmets with battery boxes installed in some embodiments of the present disclosure, safety hazards can be reduced and safety can be improved. Specifically, the wearing comfort is poor, and it is easy to leak electricity when exposed to rain. Therefore, the reason for the existence of many safety hazards is that in the construction scene where video shooting is required, in order to store electricity for the shooting equipment, a battery pack is often mounted behind the helmet, and this battery pack is at the rear of the helmet. Based on this, the safety helmets with battery boxes installed in some embodiments of the present disclosure include: a safety helmet shell, an elastic buckle and a battery box. Among them, at least one group of transversely symmetrical vents are provided at the top of the above-mentioned safety helmet shell. At least one group of protrusions are provided laterally on both sides of the above-mentioned elastic buckle. In the working state, the protrusions of the above-mentioned elastic buckle are correspondingly embedded in the vents to fix the elastic buckle to the top of the inside of the above-mentioned safety helmet shell. The above-mentioned battery box is fixedly connected to the above-mentioned elastic buckle. Among them, a battery assembly is provided in the above-mentioned battery box, and the above-mentioned battery assembly is used to power the electrical equipment attached to the above-mentioned safety helmet. Therefore, by adding an elastic buckle to the top of the helmet, the battery box can be fixed. Thus, the battery box is loaded inside the helmet to protect it from wind and rain, reducing the risk of leakage. Further, safety hazards are reduced and safety is improved.

[0047] See below Fig. 9 , Fig. 9 A flowchart 900 is shown of some embodiments of a helmet wearing detection method according to the present disclosure.

[0048] In the process of using the above technical solutions to solve the technical problems in the background technology, the following technical problem 3 is often accompanied: when workers wear safety helmets to work, there are often extreme weather conditions, such as strong winds, high temperatures, etc. As a result, workers often wipe their sweat, or are blown by the wind, or shake their heads during construction work, causing the safety helmets to tilt. As a result, it is not only difficult for the shooting equipment to accurately capture the construction scene, which is not conducive to the progress of subsequent work. It is also easy to cause safety accidents due to improper wearing of safety helmets.

[0049] Therefore, in response to the above-mentioned technical problem three, combined with the relevant technologies available, we can determine the following solution.

[0050] The helmet wearing detection method for a safety helmet comprises the following steps:

[0051] Step 901, obtaining a video of the construction scene through a shooting device attached to a safety helmet.

[0052] In some embodiments, the execution subject of the safety helmet wearing detection method can obtain the construction scene video through the shooting device attached to the safety helmet. The shooting device is provided with an inertial sensor, which can be used to output the inertial information corresponding to the same time as each frame of the construction scene image in the construction scene video. Here, the inertial information can include angular velocity values ​​in the horizontal, longitudinal and vertical directions.

[0053] Step 902: Select stable frames from the construction scene video to generate a stable image of the construction scene.

[0054] In some embodiments, the execution subject may select stable frames of the construction scene video to generate a frame construction scene stabilized image. Specifically, the clarity detection algorithm may be used to perform clarity detection on each construction scene video frame image in the construction scene video to obtain a clarity sequence. Secondly, the construction scene video frame image with the highest clarity in the corresponding clarity sequence may be determined as the frame construction scene stabilized image.

[0055] As an example, the clarity detection algorithm may include but is not limited to at least one of the following: a Laplacian Gradient Method, a Tenengrad Gradient Method based on a Sobel operator.

[0056] Optionally, the image processing algorithm set in the above-mentioned shooting device can be used to process each construction scene video frame image. For example, the image can be motion compensated by an optical flow method (including Lucas-Kanade optical flow method, Horn-Schunck optical flow method, etc.). Then, by comparing the jitter amount and blur of each construction scene video frame image, the clearest and most stable construction scene video frame image can be selected as a stable construction scene image.

[0057] Step 903: extract scene feature points from the frame construction scene stabilized image to generate a scene feature point set.

[0058] In some embodiments, the execution subject may extract scene feature points from the stable image of the construction scene to generate a scene feature point set. The scene feature point extraction may be extracting feature points corresponding to the construction scene in the stable image of the construction scene. For example, feature points of fixed machines and feature points of buildings may be extracted. Here, scene feature points may be extracted from the stable image of the construction scene using a preset feature point extraction algorithm to generate a scene feature point set.

[0059] Specifically, first, the scene feature points of the stable image of the construction scene can be extracted by the feature point extraction algorithm to obtain a preliminary identification feature point set. Then, the feature description algorithm can be used to determine the feature descriptor of each preliminary identification feature point. Here, the feature descriptor can include corresponding feature information. For example, the feature information can be a person feature point, a moving object feature point, or a fixed object feature point. Thus, the preliminary identification feature points of the fixed objects in the scene in the preliminary identification feature point set can be used as scene feature points to obtain a scene feature point set.

[0060] In practice, considering that there are many feature points in the construction scene, in order to avoid occupying more processing resources of the processing unit of the shooting equipment, the number of feature points can be greatly reduced by extracting the feature points of a specific construction scene in the stable image of the construction scene. This reduces the occupation of computing resources. At the same time, because the extracted feature points are feature points of fixed objects in the construction scene, they can be used as fixed features to facilitate reverse judgment of whether the helmet is worn stably.

[0061] As an example, the feature point extraction algorithm may include but is not limited to at least one of the following: SIFT (Scale-invariant Feature Transform) algorithm, Surf (Speeded Up Robust Features) algorithm, Harris corner detection, etc. The feature description algorithm may include but is not limited to at least one of the following: Binary Robust Independent Elementary Features (binary robust independent basic features) feature descriptor algorithm, Oriented FAST and Rotated BRIEF (with directional FAST and rotation BRIEF) feature descriptor algorithm.

[0062] Step 904 , performing image horizontal line verification on the stable image of the construction scene according to the scene feature point set to generate a horizontal verification result.

[0063] In some embodiments, the execution subject may perform image horizontal line verification on the stable image of the construction scene according to the scene feature point set to generate a horizontal verification result. The scene feature points in the scene feature point set are clustered to generate at least one cluster feature point group. Each cluster feature point group may correspond to a fixed object in the construction scene. Secondly, feature fitting may be performed on each cluster feature point in each cluster feature point group through a linear regression equation. Finally, the angle between each fitted straight line equation and the transverse center axis of the stable image of the construction scene may be determined. In response to determining that the average value of the angle is greater than a preset angle threshold. The result mark characterizing the tilt state of the horizontal verification is determined as the horizontal verification result of the stable image of the construction scene. Otherwise, the image horizontal verification passes.

[0064] Step 905 , in response to determining that the horizontal verification result indicates that the stable image of the construction scene is in a tilted state, performing a helmet wearing tilt detection based on various inertial information.

[0065] In some embodiments, the execution subject may perform helmet wearing tilt detection based on various inertial information in response to determining that the horizontal verification result is a characterization that the stable image of the construction scene is in a tilted state. Among them, the angular velocity values ​​in the horizontal, longitudinal and vertical directions included in the inertial information in the preset time period before and after the corresponding time point of the stable image of the construction scene can be numerically selected to select the horizontal angular velocity sequence, the longitudinal angular velocity sequence and the vertical angular velocity sequence greater than the corresponding threshold. Secondly, take the average value of the horizontal angular velocity sequence, the longitudinal angular velocity sequence and the vertical angular velocity sequence to obtain the horizontal angular velocity mean, the longitudinal angular velocity mean and the vertical angular velocity mean. Finally, in response to the horizontal angular velocity mean, the longitudinal angular velocity mean and the vertical angular velocity mean being greater than the corresponding tilt threshold, and the horizontal angular velocity sequence, the longitudinal angular velocity sequence and the vertical angular velocity sequence having at least one angular velocity greater than the preset tilt peak value, the identification of the helmet wearing tilt is determined as the helmet wearing tilt detection result. Otherwise, it is determined that the helmet is worn normally.

[0066] Step 906, in response to determining that the helmet wearing detection is in a tilted state, a helmet wearing correction prompt is executed through a shooting device or an audio transmission device attached to the helmet.

[0067] In some embodiments, the above-mentioned execution subject can respond to determining that the helmet wearing detection is in a tilted state, and execute a helmet wearing correction prompt through the shooting device or audio transmission device attached to the above-mentioned helmet. Among them, first, the direction of the angular velocity greater than the preset tilt peak in the lateral angular velocity sequence, the longitudinal angular velocity sequence and the vertical angular velocity sequence can be determined as the tilt direction. Then, the helmet wearing correction prompt text can be generated according to the tilt direction. For example, if the tilt direction is lateral, the helmet wearing correction prompt text is: the helmet is tilted laterally. Finally, the helmet wearing correction prompt can be executed through the audio transmission device or the audio playback unit on the shooting device. That is, the helmet wearing correction prompt text is played to achieve the purpose of prompting workers to adjust their helmets.

[0068] The above steps 901-906 and their related contents, as an inventive point of an embodiment of the present disclosure, solve the above-mentioned technical problem three "how to detect the skewed state caused by unexpected situations of the safety helmets during the workers' construction work, thereby reminding the workers to adjust the position of the safety helmets to improve safety". It makes it difficult for the shooting equipment to capture the construction scene, which is not conducive to the progress of subsequent work. The factors that are also prone to safety accidents due to improper wearing of safety helmets are often as follows: in the process of workers wearing safety helmets to work, there are often extreme weather conditions, such as strong winds, high temperatures, etc. As a result, there are often actions such as workers wiping sweat, being blown by the wind, or shaking their heads during construction work, which causes the safety helmets to tilt. If the above factors are solved, workers can be reminded in time to correct the wearing position of the safety helmets, and the purpose of improving safety and accurately capturing the construction scene can be achieved. In order to achieve this effect, first of all, considering that workers are often in motion during construction, stable frame selection can be used to select a stable construction scene image. This makes it easy to extract features from the image. Secondly, feature point extraction can be used to extract feature points in a specific construction scene from a stable image of the construction scene, which can not only be used to greatly reduce the number of feature points, but also can be used as a fixed feature to facilitate reverse judgment of whether the helmet is worn stably. Then, through horizontal line verification, it can be used to determine whether the angle of the captured image has an inclination relationship with the actual object in the scene. In this way, it is determined whether the captured image is skewed. Here, considering that the tilt of the captured image is a normal construction action of the worker, although it can be determined whether the shooting angle is tilted, it is difficult to determine whether it is artificially tilted or tilted by the helmet. Therefore, the inertial data output by the inertial sensor in the shooting device is introduced to further determine the position and posture of the shooting device. Thus, it can be effectively determined whether the helmet is tilted. Furthermore, the worker can be reminded in time to correct the position of the helmet, and the purpose of improving safety and accurately capturing the construction scene can be achieved.

[0069] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
