The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1 to 5, an image capturing apparatus 200 of the present application includes an illumination lamp 210 and a camera 220, the illumination lamp 210 is used for providing illumination, and the camera 220 is used for collecting image data within an illumination range of the illumination lamp 210. The camera 220 is disposed at the first end S1 of the image capturing device 200, a line between the center of the lens of the camera 220 and the focal point is defined as a first straight line L1, and a ratio of a degree (unit: degree) of a field angle of the camera 220 to a maximum distance (unit: cm) value of the image capturing device 200 on a second straight line L2 perpendicular to the first straight line L1 is in a range of 22.5 to 43.

The camera device 200 may be driven by the rock drilling rig 100. The drilling equipment 100 is generally provided with a drill rod 110, the drill rod 110 is matched with a drill bit to form a geological prediction hole, the drill bit is removed from the drill rod 110 during operation, then the camera device 200 is fixedly connected to the drill rod 110, and the drill rod 110 drives the camera device 200 to push into the formed geological prediction hole for detection, and the connection mode can be that the second end S2 of the camera device 200 is connected to the drill rod 110 in a threaded manner.

The illumination lamp 210 is used for illuminating the geological prediction hole, in this embodiment, the rock hole drilled on the rock is specified, the camera 220 is arranged at the first end S1 of the camera device 200, the illumination lamp 210 and the camera 220 are located at the same side of the camera device 200, and when the camera 220 shoots or takes a picture, the illumination lamp 210 is used for illuminating the camera 220.

In the related art, an angle formed by a line between the center of the lens of the camera 220 and a border of the maximum range that the camera 220 can capture is called a field angle of the camera 220, and a larger field angle of the camera 220 indicates a larger range that the camera 220 can capture.

When photographing a rock hole, the larger the field angle of the camera 220, the better when other factors are not considered. In order to obtain a larger angle of view, a specific camera 220 is required, and the camera 220 needs to be disposed from the first end S1 of the image pickup device 200 to a direction away from the second end S2 of the image pickup device 200 as far as possible to reduce the shielding of the camera 220 when the image pickup device 200 is mounted with the camera 220. However, this would certainly cause a problem that the farther the camera 220 is extended out of the image pickup device 200, the lower the connection strength thereof with the image pickup device 200 becomes, and in addition, the greater the probability that the camera 220 is hit by crushed stone that may be dropped in a rock hole. Therefore, selecting a camera 220 with a proper angle of view and a minimum distance from the camera 220 to the image capturing apparatus 200 are needed to be solved.

In this embodiment, a line on which a line connecting the center of the lens of the camera 220 to the focal point is defined is a first line L1. The ratio of the degree defining the angle of view of the camera 220 to the maximum distance of the camera device 200 on the second straight line L2 perpendicular to the first straight line L1 is in the range of 22.5 to 43, e.g. 25, 30, 35, 40, 43, the width of the camera device 200 being selectable according to the aperture of the rock hole. For example, when the maximum distance of the image capturing apparatus 200 on the second straight line L2 (i.e. the width of the image capturing apparatus 200) is 6.4 cm, the range of the angle of view of the camera 220 may be 144 ° to 275.2 °, and according to the parameters of the existing camera 220 in the market, the camera 220 with the angle of view of 150 ° to 270 ° may be preferably used. The magnitude of the angle of view of the camera 220 is determined according to the ratio of the maximum distance in the width direction of the image pickup device 200 perpendicular to the length direction thereof to the degree of the angle of view of the selected camera 220.

The size of the field angle of the camera 220 may also be determined according to the distance of the first end S1 of the camera device 200 from the furthest end of the camera 220. As measured according to the experimental results, when the maximum diameter of the image capturing apparatus 200 in this embodiment is selected to be 6 cm, referring to fig. 5, the angle a of the field angle of the camera 220 is preferably about 220 °, so that the structural details of the interior of the rock hole can be captured more clearly and completely.

The illumination lamps 210 are circumferentially distributed on the periphery of the camera 220, and the illumination lamps 210 can be LED lamps. The plurality of illumination lamps 210 are arranged on the image pickup device 200, the distance from each illumination lamp 210 to the camera 220 is consistent, the arrangement intervals of the illumination lamps 210 around the camera 220 are approximately equal, and the situation that shadows exist in the content shot by the camera 220 due to different distances among the illumination lamps 210 is avoided.

Opposite the first end S1 of the image pickup device 200 along the first straight line L1 is a second end S2 of the image pickup device 200; the distance from the camera 220 to the second end S2 of the camera device 200 is greater than the distance from the illumination lamp 210 to the second end S2 of the camera device 200. That is, in the first straight line L1 direction, the position of the camera 220 is farther from the second end S2 of the image pickup apparatus 200 with respect to the illumination lamp 210. In the detection process, when the camera device 200 is driven by the rock drilling equipment 100 to push into a rock hole, the camera 220 is positioned in front of the illuminating lamp 210, so that the situation that the camera 220 cannot focus or the exposure of the camera 220 is disordered due to the light of the illuminating lamp 210 when the camera 220 shoots is effectively avoided.

Based on the above scheme, the image pickup device 200 of the application can realize image data acquisition of mountain geologic prediction holes with a depth of tens of meters, and ensure imaging quality so that a user can observe the internal condition of a rock hole.

The camera device 200 further includes a battery 230, the battery 230 is electrically connected to the camera 220 and/or the illumination lamp 210, the battery 230 supplies power to the camera 220 and/or the illumination lamp 210, and the battery 230 is disposed between the camera 220 and the second end S2 of the camera device 200. The battery 230 is provided inside the image pickup device 200. The camera device 200 is further provided with at least one housing, and the battery 230 is disposed inside the housing. The image pickup device 200 includes a first end S1 and a second end S2 opposite to the first end S1, the camera 220 is disposed at the first end S1 of the image pickup device 200, and the battery 230 is disposed between the first end S1 and the second end S2. The housing forms a receiving cavity for receiving the camera 220 and/or the battery 230, and has or is connected to a connection interface provided at the second end S2 of the camera device 200. The connection is used for connecting the drill rod 110, and is configured as a connection groove, and the drill rod 110 is provided with a connection protrusion corresponding to the connection groove. For example, when the interface slot is screwed with the interface protrusion, the interface slot and the interface protrusion are provided with mutually cooperating screw threads so that the camera device 200 can be connected with the rock drilling rig 100.

The camera device 200 further includes a light-transmitting cover 240, where one end of the light-transmitting cover 240 along the direction of the first line L1 is open, and one end of the light-transmitting cover 240 that is open is fixedly connected to the camera device 200, so that the camera 220 is wrapped in a cavity formed by the light-transmitting cover 240 and the camera device 200. The light-transmitting cover 240 is made of transparent materials, and the light-transmitting cover 240 needs to have certain hardness to protect the camera 220 and prevent falling rocks on the side wall of the rock hole from dropping to crush the camera 220. Meanwhile, the light-transmitting cover 240 cannot be obstructed when the camera 220 takes a picture or video of the inside of the rock hole. For example, transparent plastic can be selected as the material of the transparent cover 240 to meet the requirements of this solution. The light-transmitting cover 240 is at least partially configured in a hemispherical shape, and has an opening at one end thereof, and the end of the light-transmitting cover 240 having the opening is fixedly connected to the first end S1 of the image pickup device 200. The hemispherical cavity formed by the transparent cover 240 wraps the camera 220 therein, so that in order to achieve a good shooting effect, the distances between the camera 220 and any point on the hemispherical surface of the transparent cover 240 are equal, and the influence of the transparent cover 240 on shooting of the camera 220 is reduced to the greatest extent.

The range of the minimum distance from the furthest end of the light-transmitting cover 240 projected on the first plane P1 passing through the first line L1 to the projection of the first end S1 of the image capturing device 200 on the first plane P1 is 15 mm to 25 mm, and the specific values may be: 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm. If the light-transmitting cover 240 is far away from the first end S1 of the image capturing device 200, the connection strength of the connection part will be affected, and the light-transmitting cover 240 may be damaged when falling rocks fall from the hole wall in the rock hole; when the light-transmitting cover 240 is too close to the first end S1 of the camera device 200, the requirement of the field angle of the camera 220 cannot be satisfied. The minimum distance from the furthest end of the light-transmitting cover 240 projected on the first plane P1 to the first end S1 of the image capturing device 200 projected on the first plane P1 is 15 mm to 25 mm, which can satisfy the requirements of both cases.

The illumination lamps 210 are circumferentially distributed on the periphery of the transparent cover 240, that is, on the cross section of the image pickup apparatus 200, the transparent cover 240 is located between the illumination lamps 210 and the cameras 220, the transparent cover 240 is wrapped by the cameras 220 only into a cavity formed by the transparent cover, and the illumination lamps 210 are located on the periphery of the transparent cover 240. When the illumination lamp 210 is disposed in the chamber formed by the light-transmitting cover 240, even though the light-transmitting cover 240 has high light transmittance, it is unavoidable to refract and reflect light. Therefore, when the illumination lamp 210 is located inside the transparent cover 240, the light emitted by the illumination lamp enters the camera 220 through the reflection of the transparent cover 240, so as to affect the shooting effect of the camera 220. Therefore, the illumination lamp 210 is arranged at the periphery of the light-transmitting cover 240, so that the influence of the illumination lamp 210 on the imaging quality of the camera 220 can be further reduced.

One end of the light-transmitting cover 240 provided with an opening is connected or provided with a light shielding part 241, and the light shielding part 241 is arranged between the illuminating lamp 210 and the light-transmitting cover 240. Because the path of the light emitted by the illumination lamp 210 gradually expands and expands, the light at the outermost periphery of the illumination lamp 210 passes through the camera 220 and thus has a certain influence on the imaging of the camera 220. Therefore, a light shielding portion 241 is disposed at the end of the light-transmitting cover 240 with the opening, and the light shielding portion 241 is used for reflecting or shielding the light emitted by the illumination lamp 210, which may affect the imaging of the camera 220, so as to avoid the phenomena of inaccurate exposure and halation of the camera 220.

The camera device 200 further comprises a centralizer 250, and the centralizer 250 is disposed on one side of the camera head 220. The centralizer 250 has a certain elasticity, and can enable the camera 220 to always shoot image information according to preset parameter information. Centralizer 250 is designed as a shuttle, is made of hard plastic or similar material, and can be removed and replaced.

Through the scheme, the imaging quality of the camera can be further ensured.

The foregoing description is only of the preferred embodiments of the present disclosure and description of the principles of the technology being employed.
