[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application.

[0044] In order to solve the quality problems and lag of blasting images, the present application provides a blasting image acquisition method for the blasted rock surface. The blasting image acquisition method for the blasted rock surface provided by the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] Please see attached Figure 1 , Figure 1 A flow chart of a method for collecting blasting images of a blasted rock mass surface provided in an embodiment of the present application. A blasting image collection system applied to a blasted rock mass surface includes a controller, a camera, and a detonator. The controller is electrically connected to the camera and the detonator, respectively. The detonator is used to detonate the blasted rock mass surface. The method may include the following steps:

[0046] Step S101: The controller obtains the range and position of the surface of the blasted rock mass, as well as the resolution, lens focal length and unit pixel size of the camera, and speckles are set on the surface of the blasted rock mass.

[0047] It should be noted that the range of the blasted rock surface refers to the physical size of the rock surface to be blasted, including the width and height of the blasted rock surface. The position of the blasted rock surface refers to the specific position of the rock surface to be blasted in space, which can be a three-dimensional coordinate (such as X, Y, Z coordinates). The resolution of the camera refers to the degree of image detail that the camera can capture, including the horizontal resolution and vertical resolution of the camera. The focal length of the lens determines the distance range within which the camera can clearly image. The unit pixel size refers to the size of the physical space occupied by a pixel on the camera sensor.

[0048] The rock mass within the shooting range needs to be leveled to eliminate the visual interference caused by unevenness and ensure that the camera can capture clear images. Spray a layer of primer on the leveled rock mass. This primer is usually used to enhance the adhesion and contrast of the rock mass surface, providing a good foundation for the subsequent speckle production. Spray a layer of matte primer as thin as possible on the surface of the blasted rock mass. Matt primer can reduce reflections, making the speckle more visible during the blasting process, and will not affect the clarity of the image due to excessive reflections. Use paint with a high contrast with the primer to produce speckles of appropriate size on the matte primer. Speckle is a commonly used technology in blasting measurement. By recording the changes in speckle before and after blasting, the deformation and damage of the rock mass can be analyzed. The size and distribution of speckle need to be determined according to the specific blasting experiment and design requirements.

[0049] Step S102: The controller determines the shooting range of the camera based on the range of the blasted rock mass surface and the resolution of the camera.

[0050] In the present application, the controller can first determine the initial shooting range of the camera based on the width and height of the blasted rock body surface, and then the controller corrects the initial horizontal size and initial vertical size of the camera based on the horizontal resolution and vertical resolution of the camera to obtain the shooting range of the camera.

[0051] It should be noted that the initial shooting range of the camera includes the initial horizontal size S of the camera. H ' and initial longitudinal size S V '. The camera's shooting range includes the camera's horizontal size S H and vertical dimension S V .

[0052] Specifically, the range of the blasted rock mass determines the size of the field of view that the camera needs to cover. In order to ensure that the entire rock mass surface can be photographed, the controller determines an initial shooting range of the camera, which is slightly larger than the actual size of the blasted rock mass surface to ensure that the entire rock mass surface can be photographed. That is, the initial longitudinal size S of the camera H 'Slightly larger than the width of the blasted rock mass, the initial longitudinal size of the camera SV ' is slightly larger than the height of the exploded rock surface. According to the lateral resolution R of the camera H With the vertical resolution R V , the initial horizontal size S of the camera H ' and initial longitudinal size S V 'Make corrections to ensure that the captured image meets the resolution requirements and finally determine the horizontal size S of the camera H and vertical dimension S V , please refer to the following formula for details:

[0053] S H =max{S H ' / R H ,S V ' / R V}×R H

[0054] S V =max{S H ' / R H ,S V ' / R V}×R V

[0055] Step S103: The controller determines the position of the camera based on the focal length of the camera lens, the unit pixel size, the shooting range, the resolution and the position of the blasted rock surface.

[0056] In the present application, the controller may first calculate the shooting distance based on the focal length of the camera lens, the unit pixel size, the shooting range, the resolution and the position of the exploded rock body surface. The controller then calculates the position of the camera based on the shooting distance and the position of the exploded rock body surface.

[0057] As an implementation method, the controller is based on the focal length f of the camera lens, the unit pixel size S pixel , lateral dimension S H and lateral resolution R H , calculate the shooting distance W, which is used to indicate the distance between the camera and the blasted rock surface. For details, please refer to the following formula:

[0058]

[0059] As another possible implementation method, the controller is based on the focal length f of the camera lens, the unit pixel size S pixel , longitudinal dimension S V and the vertical resolution R V , calculate the shooting distance W, which is used to indicate the distance between the camera and the blasted rock surface. For details, please refer to the following formula:

[0060]

[0061] Step S104: the controller sends a detonation instruction to the detonator and simultaneously sends a shooting instruction to the camera, so that the camera can shoot a blasting image of the speckle in the surface of the blasted rock mass.

[0062] Before the controller sends the command, place the camera at the calculated camera position and adjust the camera angle so that the camera can clearly observe the speckle in the blasted rock surface. Install the camera safety protection device, place the camera tripod on the safety protection platform and adjust it to a suitable height, and tighten the tripod to prevent it from moving. Select the location where the detonation signal is sent according to the on-site terrain conditions and blasting safety regulations, and arrange the controller at the location where the detonation signal is sent. The camera has been set for pre-recording time and is on standby, ready to receive shooting instructions. The detonator has been installed in place and is in a detonable state, waiting to receive the detonation command.

[0063] In the present application, the controller receives a start signal from the operator or reaches a preset start condition. The controller sends instructions to the detonator and the camera at the same time: sends a detonation instruction to the detonator, which is transmitted to the detonator through the detonation line to trigger an explosion reaction on the surface of the blasted rock mass; sends a shooting instruction to the camera, which is transmitted to the camera through the recording trigger control line, so that the camera can capture the blasting image of the speckle on the surface of the blasted rock mass at the moment of the blasting.

[0064] In summary, the present application provides a method for acquiring blasting images of a blasted rock face, the method being applied to a blasting image acquisition system for a blasted rock face, the system comprising a controller, a camera and a detonator, wherein the detonator is used to detonate the blasted rock face, the method comprising: the controller acquiring the range and position of the blasted rock face, as well as the resolution, lens focal length and unit pixel size of the camera; the controller determining the shooting range of the camera based on the range of the blasted rock face and the resolution of the camera; the controller determining the position of the camera based on the lens focal length, unit pixel size, shooting range, resolution and position of the blasted rock face of the camera, determining the exact position of the camera through precise calculation, which is conducive to acquiring high-quality blasting images; the controller sending a detonation command to the detonator and simultaneously sending a shooting command to the camera, so as to realize the synchronization of blasting and shooting, ensuring that the camera can capture the blasting image of the blasted rock face in real time, which is helpful to timely understand the blasting effect.
