Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically to a non-contact geological occurrence measurement device, measurement method, equipment, and medium. Background Technology

[0002] Geological occurrence refers to the spatial position of structural lines or surfaces. It describes the direction of extension and the degree of inclination of geological interfaces (such as bedding planes, faults, joints, etc.) in three-dimensional space.

[0003] Traditional geological attitude measurement all use contact measuring devices. Contact measuring devices require the compass disc to be physically in contact with the rock surface being measured. Therefore, their drawbacks are:

[0004] (1) Significant safety hazards: Surveyors need to be close to steep, broken, and dangerous rock walls;

[0005] (2) Limited application: It cannot be measured on surfaces that are difficult to access, such as the roof of a cave or a cliff face near water.

[0006] (3) Accuracy is affected: The magnetic properties of rock minerals can cause errors in magnetic needle measurement.

[0007] Meanwhile, although precision surveying instruments such as total stations and 3D laser scanners can achieve non-contact measurement, their drawbacks are that the equipment is bulky, expensive, and complex to operate (requiring professional training and tripod setup), which cannot meet the needs of rapid and flexible geological field operations.

[0008] Therefore, the present invention aims to provide a non-contact geological occurrence measurement device, measurement method, equipment and medium to solve the aforementioned related problems. Summary of the Invention

[0009] The technical problem this invention aims to solve is that existing contact-type measuring devices have limited applications, and non-contact measuring devices cannot meet the needs of rapid and flexible geological field measurements. The purpose is to provide a non-contact geological attitude measurement device, method, equipment, and medium. This device uses an attitude sensing module to sense the attitude data of the measuring device in real time, providing displacement jitter compensation during spatial coordinate construction, thereby improving the uniformity of coordinate parameters and the reliability of measurement results. A distance measuring module measures the distance values ​​of multiple target points on the surface of the structure under test, obtaining the plane normal vector of the surface without contact, and thus calculating the geological attitude, achieving a non-contact, flexible, and rapid measurement objective.

[0010] This invention is achieved through the following technical solution:

[0011] A non-contact geological occurrence measurement device, the device comprising:

[0012] The electronic compass module is used to obtain the geographical location of the measurement point;

[0013] The ranging module is used to obtain the distance values ​​from the measurement point to multiple target points on the surface of the structure to be measured;

[0014] The attitude sensing module is used to acquire the attitude data of the measuring device;

[0015] The data processing module is used to construct a three-dimensional spatial coordinate system based on the geographical orientation obtained by the electronic compass module, and to calculate the geological attitude of the structural surface to be measured by combining the distance value measured by the ranging module and the attitude data obtained by the attitude perception module with the three-dimensional spatial coordinate system.

[0016] Furthermore, the device also includes:

[0017] The display module is used to display the calculated geological occurrence of the structural surface to be measured;

[0020] A three-dimensional spatial coordinate system is constructed with the measurement point as the origin, the north direction as the Y-axis, the east direction as the X-axis, and the vertical direction as the Z-axis.

[0021] The coordinate parameters of multiple target points on the surface to be measured in a three-dimensional spatial coordinate system are obtained. The plane normal vector is calculated using the coordinate parameters of the multiple target points, and the geological attitude of the surface to be measured is calculated based on the plane normal vector.

[0022] Furthermore, the coordinate parameters of multiple target points on the surface of the structure under test in the three-dimensional spatial coordinate system are obtained, specifically as follows:

[0023] The distance values ​​from the measurement point to multiple target points on the surface of the structure to be measured, as well as the attitude data of the measuring device, are obtained respectively. The coordinate parameters of the corresponding target point are calculated by using the distance value of each target point and the attitude data of the measuring device.

[0024] Furthermore, the geological occurrence includes dip value and dip angle value.

[0025] Furthermore, the geological attitude of the structural surface to be measured is calculated based on the plane normal vector. Specifically, the dip angle is calculated using the angle between the plane normal vector and the horizontal plane, and the dip direction is calculated using the angle between the projection line of the plane normal vector on the horizontal plane and the Y-axis.

[0026] Furthermore, the attitude data includes azimuth and pitch angles.

[0027] The present invention also provides a computer device, including a system memory and a processor, wherein the system memory stores a computer program, and the processor executes the computer program to implement the steps of any of the methods described above.

[0028] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of any of the methods described above.

[0029] The present invention also provides a computer program product containing instructions that, when executed by a cluster of computer devices, cause the cluster of computer devices to perform the method described in any of the preceding claims.

[0030] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0031] In this invention, the attitude sensing module senses the attitude data of the measuring device in real time, which can provide displacement jitter compensation during the spatial coordinate construction process, thereby improving the uniformity of coordinate parameters and the reliability of measurement results.

[0039] Example 1

[0040] See Figure 1 , Figure 1 A schematic diagram of the module connection of a non-contact geological occurrence measurement device is shown, wherein the device includes:

[0041] The electronic compass module is used to obtain the geographical location of the measurement point;

[0042] The ranging module is used to obtain the distance values ​​from the measurement point to multiple target points on the surface of the structure to be measured;

[0043] The attitude sensing module is used to acquire the attitude data of the measuring device;

[0044] The data processing module is used to construct a three-dimensional spatial coordinate system based on the geographical orientation obtained by the electronic compass module, and to calculate the geological attitude of the structural surface to be measured by combining the distance value measured by the ranging module and the attitude data obtained by the attitude perception module with the three-dimensional spatial coordinate system.

[0045] The display module is used to display the calculated geological occurrence of the structural surface to be measured;

[0046] The communication module is used to connect to the terminal device and send the geological occurrence of the structure to be measured to the terminal device.

[0047] In this embodiment, the operator holds and activates the measuring device, using an electronic compass module to obtain the geographical location of the current measuring point. This geographical location is then transmitted to the data processing module to construct a three-dimensional spatial coordinate system, thereby establishing a directional reference for the measurement. Next, a distance measuring module is used to obtain the distance from the measuring point to a target point on the structure to be measured. An attitude sensing module is used to obtain attitude data at the time of measurement. The data processing module calculates the coordinate parameters of the target point in the three-dimensional spatial coordinate system using the attitude data and distance values. The coordinate parameters of the other two target points are obtained and calculated in the same way. The normal vector of the structure to be measured is calculated using the coordinate parameters of the three target points. The geological attitude of the structure to be measured is calculated using the normal vector. The calculated geological attitude is sent to the display module for display and then transmitted to the terminal device via the communication module. The terminal device further processes the data.

[0048] It should be noted that in this embodiment, the ranging module uses a laser ranging sensor, but other ranging devices can be used in other embodiments, and no further restrictions are imposed here; similarly, the attitude sensing module uses an inertial measurement unit (IMU, integrating a three-axis accelerometer and a three-axis gyroscope), but other attitude sensing modules can be used in other embodiments, and no further restrictions are imposed here; furthermore, this embodiment uses three target points for illustration, but other numbers of target points can be designed according to actual needs in other embodiments; and the terminal device can be a mobile device, a computer device, or other terminal device, and no further restrictions are imposed here.

[0049] Specifically, in this embodiment, the attitude perception module senses the attitude data of the measuring device in real time, which can provide displacement jitter compensation during the spatial coordinate construction process, thereby improving the uniformity of coordinate parameters and the reliability of measurement results. The distance value of multiple target points on the surface of the structure to be measured is measured by the ranging module, and the plane normal vector of the surface of the structure to be measured is obtained without contact, thereby calculating the geological attitude. This achieves the purpose of non-contact, flexible and fast measurement, and solves the technical problem that the application of existing contact measuring devices is limited and non-contact measuring devices cannot meet the needs of rapid and flexible geological field operations.

[0051] This invention also provides a non-contact geological occurrence measurement method, which is used in the non-contact geological occurrence measurement device described in Embodiment 1 above. See [link to related documentation]. Figure 2 , Figure 2 A flowchart illustrating a non-contact geological attitude measurement method is shown, wherein the method includes:

[0052] S1: Construct a three-dimensional spatial coordinate system with the measurement point as the origin, the north direction as the Y-axis, the east direction as the X-axis, and the vertical direction as the Z-axis;

[0053] S2: Obtain the coordinate parameters of multiple target points on the surface to be measured in a three-dimensional spatial coordinate system, calculate the plane normal vector using the coordinate parameters of the multiple target points, and calculate the geological attitude of the surface to be measured based on the plane normal vector.

[0054] Specifically, in this embodiment, the distance values ​​from the measurement point to multiple target points on the surface of the structure to be measured are first obtained, along with the attitude data of the measuring device at the corresponding measurement time. Using the distance value of each target point and the attitude data of the measuring device, the coordinate parameters of the corresponding target point are calculated. The attitude data includes azimuth and pitch angles, calculated as follows: X1 = S1×cos(α1)×sin(φ1), Y1 = S1×cos(α1)×cos(φ1), Z1 = S1×sin(α1), where X1, Y1, and Z1 represent the coordinate parameters of the first target point, S1 represents the distance value of the first target point, α1 represents the pitch angle of the measuring device when measuring the first target point, and φ1 represents the azimuth angle of the measuring device when measuring the first target point. Following the above measurement method, two more target points different from the first target point are measured. Then, the plane normal vector is calculated using the coordinate parameters of multiple target points, specifically n=(P2-P1)×(P3-P1)=(A,B,C), where P1, P2, and P3 represent the three target points respectively. Finally, the tilt angle is calculated using the angle between the plane normal vector and the horizontal plane, specifically: δ=90°-arccos(C / |n|). The dip angle is calculated using the angle between the projection line of the plane normal vector on the horizontal plane and the Y-axis, specifically θ=arctan2(A,B).
