Abstract
Description
Technical Field
[0001] This application relates to a technique for predicting the blasting range, and more particularly to a method and apparatus for predicting the blasting range. Background Technology
[0002] In the field of mine clearance equipment, mine clearance can be carried out using rocket-propelled blasting.

[0058] Figure 1 This is a schematic diagram of the overall structure of the method for estimating the blasting range according to an embodiment of this application, as shown below. Figure 1 As shown, the method for estimating the blasting range in this application embodiment includes:
[0059] Step 101: Obtain the model of the shell to be fired and the firing angle of the shell in the chamber.
[0060] In this embodiment, obtaining the model number of the shell to be fired includes: reading the identification mark set on the shell to be fired, and obtaining the model number of the shell based on the identification mark. In this embodiment, the model number can be determined by reading information such as the nameplate on the shell, for example, by taking a picture of the nameplate information area on the shell and automatically recognizing the content of the pictured image. Alternatively, as an implementation, the model number can be identified by directly reading the QR code information or other identification icons or markings on the shell.
[0061] Alternatively, as one implementation method, information on the caliber and length of the chamber of the projectile to be fired can be obtained, and the type of the projectile to be fired can be determined based on the caliber and length information. For each type of projectile, there is a corresponding firing device and firing chamber, and the type of projectile to be fired can also be determined by information such as the caliber and length of the firing chamber.
[0062] Or, as a way of implementation
[0063] Obtain the model number of the launching equipment that will fire the projectile to be fired, and determine the model number of the projectile to be fired based on the model number of the launching equipment.
[0064] The projectile to be fired in this application embodiment can be a rocket, a short- or long-range artillery shell, etc.
[0065] Step 102: Obtain the length of the explosive strip connected to the projectile to be fired, the distribution pattern of the explosive in the explosive strip, identify the type of explosive, and obtain the explosion parameters of the explosive.
[0066] In this embodiment of the application, mine clearance or area destruction is carried out by using a shell to be fired carrying an explosive charge.
[0067] Specifically, obtaining the length of the explosive strip connected to the projectile to be fired includes: acquiring image data and identifying objects in the image data; determining the explosive strip in the image data based on feature points in the objects; determining at least one of the following: the stacking position relationship between different segments of the explosive strip, the curvature in different segments, and the overlapping area between different segments; and estimating the length of the explosive strip.
[0068] In this embodiment, the explosive strip connected to the projectile to be fired is photographed to obtain relevant images. The image data is then automatically identified to determine the explosive strip. Based on the image, the spread state of the explosive strip is identified, and its length is determined based on the spread state, etc. Specifically, by analyzing the display attributes of pixels in the image, it is determined which pixels match the display attributes of preset pixels in the explosive strip, thus identifying the explosive strip. Based on the spread state of the explosive strip, it is determined whether it is in a naturally extended state, a curled state, or a coiled state, etc., and the actual length of the explosive strip is determined based on selected feature points in the image.
[0069] In this embodiment, the distribution of explosives in the explosive belt can be determined by the type of explosive belt, such as the spacing between the explosives. This distribution can also use empirical values or preset values.
[0070] The explosion parameters of explosives can be obtained from the known types of explosives, or they can be pre-input as set values, or empirical values can be used.
[0071] Step 103: Based on the type of the projectile to be fired and the firing angle, estimate the pre-firing position of the projectile to be fired; based on the pre-firing position, estimate the drop position of the explosive charge.
[0072] In this embodiment of the application, obtaining the firing angle of the projectile in the chamber includes:
[0073] The pose of the launching equipment for the projectile to be launched is obtained by a pose sensor; the pose sensor includes a gravity sensor, an orientation sensor, etc.
[0074] The positional relationship between the barrel of the launching equipment and the reference plane is determined based on the pose; the reference plane can be a horizontal plane, a vertical plane, etc.
[0075] The firing angle of the projectile in the chamber is determined based on the positional relationship.
[0076] Once the launch angle of the shell in the chamber is determined, and based on the shell type and its launch parameters, the launch distance can be determined, and subsequently, the impact area of the shell can be determined. This allows for the estimation of the drop location of the explosive charge.
[0077] Step 104: Obtain the ground condition of the area set by the drop location based on the drop location. The ground condition includes information on ground buildings and vegetation.
[0078] In this embodiment, obtaining the ground condition of a designated area based on the drop location includes: retrieving an electronic map, searching for a corresponding area in the electronic map based on the drop location, and determining the ground condition information corresponding to that area in the electronic map based on the found area. In this embodiment, the electronic map includes relevant information such as terrain, buildings, and vegetation for each location.
[0079] Step 105: Determine the impact resistance parameters of the ground buildings and the vegetation.
[0080] In this embodiment of the application, determining the impact resistance parameters of the ground building includes: obtaining the construction year and main structure of the ground building recorded in the electronic map through the electronic map, and obtaining the impact resistance parameters of the ground building in different shock wave ranges.
[0081] For each type of vegetation, impact resistance parameters can be set. For example, appropriate impact resistance parameters can be set according to the density of the vegetation and the type of vegetation.
[0082] Step 106: Based on the drop location of the explosive strip, the explosion parameters of the explosive, and the impact resistance parameters, determine the destructive effect of the explosive strip.
[0083] In this embodiment of the application, the destructive effect of the explosive belt can be determined by the explosive parameters of the explosive belt, such as the explosive power, the area covered by the explosion, and the distance between the explosive belt and ground buildings and vegetation.
[0084] Step 107: Output information about the destructive effect.
[0085] In the above scheme, the destructive effect can be output via voice broadcast, a video simulating an explosion scene, or text, to facilitate users in deciding whether to carry out the launch based on the explosion effect. Alternatively, other blasting methods can be adopted based on the simulated destructive effect, such as lengthening the explosive band or using a more powerful explosive band.
[0086] The technical solutions of the embodiments of this application can be applied to
[0087] The technical solution of this application embodiment determines the landing position of the explosive belt carried by the launched shell by collecting information on the type and angle of the launched shell. This landing position allows for the determination of the impact of the explosive belt on ground structures or vegetation in the landing area. Based on the explosive distribution and explosive power of the explosive belt, the extent of damage to the ground in the landing area is determined, and the damage is output through voice, text, or video simulation. This allows for convenient determination of whether to proceed with the launch, whether the explosive belt needs to be replaced, and whether its length needs to be increased or decreased. The technical solution of this application embodiment can pre-estimate the destructive effect of the explosive belt, ensuring its effectiveness in attacking or clearing obstacles.
