Description

Technical Field

[0001] This invention relates to the fields of geological exploration technology and oil and gas field development engineering, and particularly to a camera accessory, device, system, and application for measuring formation parameters. Background Technology

[0002] When geological exploration personnel conduct geological work outdoors (in the field), measuring the attitude of strata is of paramount importance. While measuring the attitude of strata at measurement points, they supplement their work with photographs of geological phenomena at the measurement points and field records of these phenomena. This facilitates subsequent indoor processing of completed geological work (such as geological reconnaissance, mineral geological surveys, regional geological surveys, and geological mapping at different scales, especially digital mapping, outcrop dissection and reconstruction in oil and gas field development projects, etc.).

[0003] In current geological work, the main method involves measuring the stratigraphic attitude using a compass, locating the geological coordinates of the measurement points using GPS equipment, and simultaneously photographing the measurement points. This process collects and records the stratigraphic attitude data, geological coordinate data, and photographic data for each measurement point, supplementing other geological records obtained on-site by the staff to complete a stratigraphic description of that point. However, with the ongoing large-scale mapping work, the number of measurement points is increasing exponentially. The repetitive work at individual measurement points, as well as the measurement of some key but inaccessible points, consumes enormous human and material resources. Summary of the Invention

[0004] Based on the inventor's understanding of existing technologies in this field, there is currently no systematic method or equipment in geological exploration work that can comprehensively collect stratigraphic attitude data, geological coordinate data, and photographic data of measurement points in one go. Instead, specific equipment is optimized in different work stages. For example, electronic compasses are used instead of mechanical compasses to measure stratigraphic attitude; GPS devices are used instead of the "three-point positioning method" to measure geological coordinates; digital cameras (or smartphones) are used instead of traditional film cameras to photograph geological phenomena; and handheld devices (smartphones, tablets) are used instead of hand-drawn field logs. However, these electronic devices not only fail to integrate the aforementioned measurement methods, but also suffer from high costs, the need for field workers to frequently switch between different devices to collect different data, or the need for multi-person work teams to be responsible for collecting one type of data. This not only wastes manpower and resources but also hinders work efficiency. While conducting field geological work, due to the complex geological environment, there are often some measurement points that geological surveyors cannot reach (such as measurement points located on cliff edges, waterfalls, steep walls, etc.). Taking measurements in such risky locations that cannot be directly reached will pose significant risks, while abandoning the measurement points will result in a lack of data collection.

[0005] In view of the above problems, the inventors of this invention have made this invention, which integrates the collection of stratigraphic attitude at measurement points with the photographing of geological phenomena. This not only reduces the number of portable devices and improves work efficiency, but also enables the collection of geodetic data from inaccessible measurement points while ensuring the safety of geological surveyors. This application proposes to provide a camera accessory, device, system, and application for measuring stratigraphic parameters that overcomes or at least partially solves the above problems.

[0065] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0066] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0067] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0068] This invention provides a camera accessory for measuring formation parameters. This camera accessory can be used in conjunction with a camera or used independently. (See reference...) Figures 1-3 As shown, the camera accessory 1 may include: a housing 11, a measuring component 12 disposed on the outer surface of the housing 11, an electronic compass 13 installed inside the housing 11, and a processor 14; the measuring component 12 and the electronic compass 13 are electrically connected to the processor 14 respectively; wherein, the measuring component 12 includes at least three electronic rangefinders 121 and at least two electronic protractors 122; at least two electronic rangefinders 121 are movably connected to the housing 11, and the at least three electronic rangefinders 121 are used to measure the distance between the camera accessory and the target measurement surface 4 to be measured, and send the distance to the processor 14; the at least two electronic protractors 122 are used to measure the angle between the at least two electronic rangefinders 121 movably connected to the housing 11 and the outer surface of the housing to which they are connected, and send the angle to the processor 14; the electronic compass 13 is used to measure the dip and tilt angle of the space where the camera accessory 1 is located, and send the dip and tilt angle to the processor 14; the processor 14 determines the orientation of the target measurement surface 4 based on the distance, the angle, and the dip and tilt angle.

[0069] It should be noted that the electronic rangefinder in the embodiments of the present invention includes at least two rangefinders movably connected to the outer surface of the housing, meaning that the positions of these at least two electronic rangefinders aligned with the target measurement surface can vary. In this embodiment, referring to... Figure 1As shown, for example, there are a total of four electronic rangefinders, of which at least two are movable, and the remaining ones can be either movably connected to the outer surface of the housing or fixedly connected. For example, as shown in the figure, there are four electronic rangefinders, of which the fixed rangefinders are installed perpendicular to the outer surface of the housing, i.e., parallel to the normal to the outer surface of the housing; the other three movably connected rangefinders are distributed around the fixedly connected rangefinders. In this embodiment of the invention, the positions of the electronic rangefinders can be concentrated in one location as shown in the figure, or they can be arranged separately, as long as the distance can be measured. This embodiment of the invention does not specifically limit their positions.

[0070] It should also be noted that, in this embodiment, the angle between the movable electronic rangefinder and the plane formed by the normal to the outer surface of the housing is ω. i (For reference) Figure 9A The included angle (indicated by the middle arrow) can be fixed and can be used as a constant parameter set by the factory for the camera accessory. That is, the relative positions of the movable electronic rangefinders on the circumference are fixed, and in this embodiment, at least one of the included angles ω between at least two movable electronic rangefinders and the plane formed by the normal to the outer surface of the housing is fixed.

[0071] The camera accessories described in this embodiment of the invention allow staff to remotely and non-contactly measure the stratigraphic attitude of the measurement point (target measurement surface) without having to go to the actual measurement location. This reduces the workload of staff on the ground, avoids the risks of on-site measurement in dangerous areas, and prevents the abandonment of measurement points. It is fully applicable to large-scale mapping or geological and mineral surveys (especially detailed surveys).

[0072] It is understood that the housing in the embodiments of the present invention is provided with a chamber or a receiving cavity. The electronic compass, processor and GPS positioning module mentioned below in this embodiment are all installed in the above-mentioned chamber or receiving cavity. Those skilled in the art should not have any ambiguity in this regard.

[0073] It should also be noted that, in this embodiment, when the camera accessory is used in conjunction with the camera, after connection, the camera accessory and the camera are on the same horizontal plane. After the camera is aligned with the target measurement surface to be measured, the changes in azimuth and angle of the camera accessory and the camera are consistent. At this time, the attitude information (dip and dip angle) measured by the electronic compass not only represents the attitude of the camera accessory but also the attitude of the camera. It should also be noted that, in this embodiment, the target measurement surface to be measured is the surface layer of the stratum to be measured.

[0074] It should be further noted that the accompanying drawings provided in the embodiments of the present invention are all described using three movably connected electronic rangefinders, one fixedly connected electronic rangefinder, and three electronic protractors as examples. It is understood that those skilled in the art should not limit themselves to only three movably connected electronic rangefinders, but should use at least three electronic rangefinders, of which at least two are movably connected. The method for measuring stratigraphic parameters in this embodiment can be realized by adjusting their positions, and will not be described again in this embodiment.

[0075] In an optional embodiment, reference is also made to Figures 1 to 7 As shown, the electronic rangefinder 121 is movably connected to the housing 11 so that the electronic rangefinder 121 rotates about the normal of the outer surface connected to the housing as an axis; and / or, the electronic rangefinder 121 is movably connected to the housing 11 so that the electronic rangefinder 121 can swing in the plane formed between the electronic rangefinder 121 and the normal.

[0076] In this embodiment of the invention, the electronic rangefinder is movably connected to the housing. When at least one electronic rangefinder changes position, at least one new set of measurement data can be obtained, which can then be weighted and averaged to obtain the final formation parameters. Compared to at least three fixedly connected electronic rangefinders, this invention firstly avoids the situation where, when one fixedly connected electronic rangefinder is aligned with the target measurement surface, the other fixedly connected electronic rangefinders cannot be aligned (projected) onto the target measurement surface, thus preventing the acquisition of effective data and the inability to perform measurements. Secondly, the at least two movably connected electronic rangefinders can be adjusted to align with the target measurement surface, i.e., projected onto the target measurement surface, allowing users to easily adjust them according to actual conditions at any time. Thirdly, by repeatedly adjusting the positions of the movably connected electronic rangefinders, multiple sets of measurement data can be obtained. Each set of measurement data can determine a formation parameter, and then the weighted average of multiple formation parameters yields a more accurate final formation parameter.

[0077] It should be noted that when at least two electronic rangefinders 121 are movably connected to the housing 11, allowing the rangefinders 121 to rotate about the normal to the outer surface of the housing, the angle between the rangefinder and the normal remains constant. If all three movably connected rangefinders can obtain the distance to the target surface, three sets of distance data and three sets of calculation results can be obtained. A weighted average of these results can also achieve the aforementioned method for measuring geological parameters. If the electronic rangefinders 121 are movably connected to the housing 11, allowing them to oscillate within the plane formed by the rangefinder and the normal, the rangefinders 121 cannot rotate about the normal to the outer surface of the housing, but the aforementioned method for measuring geological parameters can still be achieved.

[0078] Of course, in another specific embodiment, the above-mentioned at least two electronic rangefinders can both rotate and swing, making it more convenient and faster to adjust the electronic rangefinders, and the effective value of measuring the distance from the electronic rangefinder to the target measurement surface is more accurate, which can achieve the effect of more convenient measurement of stratum parameters.

[0079] In an optional embodiment, refer to Figure 1 and Figure 2 As shown, at least two electronic protractors 122 are mounted on the end of at least two electronic rangefinders 121 that are movably connected to the housing 11, near the housing 11. In this embodiment, the electronic protractors are positioned at the end of the electronic rangefinders near the housing, which facilitates the measurement of the angle between the electronic rangefinder and the housing's connecting surface. Compared to positioning them at the end of the electronic rangefinders away from the housing, where the protractor extends beyond the outer surface of the housing during measurement, the angle between the electronic rangefinder and the housing's connecting surface cannot be accurately measured, making the measurement work more difficult.

[0080] It should be noted that the fixed-connection electronic rangefinder and the movable-connection electronic rangefinder in the embodiments of the present invention can be of the same model, both of which are used to measure the distance to the target measurement surface to be measured. The only difference is that the fixed-connection electronic rangefinder is fixed to the surface of the housing and points in the direction of the normal to the camera surface (i.e., the direction of the normal to the outer surface of the housing connection).

[0081] In a more specific embodiment, to facilitate understanding by those skilled in the art of using the camera accessories and the processor's calculation of formation parameters in this embodiment, refer to... Figures 9A to 9D As shown, this embodiment provides one specific method for the processor to determine the orientation of the target measurement surface based on the aforementioned distance, dip, tilt angle, and included angle. Here, A is the plane where the camera lens is located; B is the normal to the plane where the camera lens is located; C is the plane formed by the normal to the plane where the camera lens is located and the movably connected electronic rangefinder. The electronic rangefinder can swing within this plane, and the plane can also rotate; this plane can also be referred to as the measuring instrument rotation plane of the electronic rangefinder.

[0082] In this embodiment, the coordinates of the camera accessory center reference point in the three-dimensional coordinate system are (x0, y0, z0), which are approximately consistent with the camera coordinates. In this embodiment, the angle between the electronic rangefinder and the outer surface connecting the housing is measured using an electronic protractor, which yields the angle between the electronic rangefinder and the normal to the outer surface, i.e., the angle between the electronic rangefinder and the camera normal. In this embodiment, the angles between the three movable electronic rangefinders and the camera surface normal are (α, β, γ); the distances from the three movable electronic rangefinders to the target measurement surface are (l1, l2, l3), and the orientation and tilt angle of the camera surface are also specified. When the camera is positioned on a horizontal plane, the included angles ω1, ω2, and ω3 between the rotation planes of the three measuring instruments are given. Therefore, the equations of the rotation planes containing the three movable electronic rangefinders are:

[0083]

[0084] The coordinates of the points corresponding to the three interconnected electronic rangefinders on the target measurement surface are: a(x1,y1,z1), b(x2,y2,z2), c(x3,y3,z3). Assume the angle ω between the three electronic rangefinders and the plane formed by the normal. i If it remains constant, then we know that:

[0085]

[0086] Based on the equations of the rotation planes containing at least three electronic rangefinders, the camera plane normal thread can be obtained as follows:

[0087]

[0088] Taking a(x1,y1,z1) as an example, the equation of the plane passing through a(x1,y1,z1) and perpendicular to the normal is:

[0089] Ax + By + Cz - (Ax1 + By1 + Cz1) = 0

[0090] Then, at the intersection point n(x,y,z) of the plane and the normal, we have:

[0091]

[0092] Combining the above system of equations, we can obtain the following relationship:

[0093]

[0094] The equation of the plane containing the target measurement surface is:

[0095] a i X+b i Y+c i Z+d i =0

[0096] We can obtain:

[0097]

[0098] Assuming the X-axis direction is north, and the target measurement surface is oriented... The calculation method is as follows: the equation of the intersection line of the target measurement surface within the XY coordinate axis is:

[0099] a i X+b i Y+di =0

[0100] The intersection point of the line with the X-axis and Y-axis is x0, y0:

[0101]

[0102]

[0103] When x0>0 and y0>0, or when x0<0 and y0<0,

[0104] When x0 < 0 and y0 > 0, or when x0 > 0 and y0 < 0,

[0105] The tilt angle of the target measurement surface to be measured is θ i The equation of the intersection line of the target measurement surface within the XZ coordinate axis is:

[0106] a i X+c i Z+d i =0

[0107] The intersection point of the line with the X-axis and Z-axis is x0, z0:

[0108]

[0109]

[0110] Inclination angle θ i for:

[0111] Let the tendency η i ,

[0112] When x0>0 and y0>0, or when x0<0 and y0<0, when z0<0 and y0>0, or when z0>0 and y0<0,

[0113] When x0>0 and y0>0, or when x0<0 and y0<0, when z0<0 and y0<0, or when z0>0 and y0>0,

[0114] When x0 < 0 and y0 > 0, or when x0 > 0 and y0 < 0, z0 < 0 and y0 < 0, or when z0 > 0 and y0 > 0,

[0115] When x0 < 0 and y0 > 0, or when x0 > 0 and y0 < 0, z0 < 0 and y0 > 0, or when z0 > 0 and y0 < 0,

[0116] The orientation of the target measurement surface to be measured is (η) i θ i ).

[0117] In an optional embodiment, refer to Figure 3 and Figure 7 As shown, the camera accessory may further include a GPS positioning module 15 disposed inside the housing 11. The GPS positioning module 15 is used to determine the spatial position of the camera accessory 1 and send the spatial position to the processor 14. The processor 14 is used to determine the spatial position of the target measurement surface 4 (i.e., the position of the actual measurement point) based on the spatial position, distance, included angle, inclination, and tilt angle of the camera accessory 1. This embodiment can determine the spatial coordinates of the measurement point (target measurement surface) by using spatial coordinates, distance, angle, etc., avoiding the inconvenience of manually locating the point on-site and also avoiding the occurrence of point loss during large-scale mapping.

[0118] In another alternative embodiment, refer to Figure 3 and Figure 6 As shown, the camera accessory may also include: a display screen 16 disposed on the surface of the housing 11; the display screen 16 is electrically connected to the processor 14 and is used to display measurement data and / or formation parameters sent by the processor 14. The display screen allows for convenient and quick observation of whether valid formation parameters have been measured, and timely adjustment of the position of the electronically connected rangefinder based on the determined formation parameters, so as to obtain more accurate results by measuring multiple sets of data and weighting and averaging them.
