Description

Technical Field

[0001] This application relates to the field of surveying and mapping technology, and in particular to a surveying and mapping point marking method, apparatus, equipment, and storage medium. Background Technology

[0002] Mapping and marking refers to recording the latitude and longitude of objects or feature points on the ground using a marking method. In related technologies, drones are typically controlled by a remote controller to perform this task. For example, after the drone takes off, it flies to the area where the mapping and marking need to be performed, and when the drone is directly above the location, the marking button is pressed to record the latitude and longitude.

[0003] However, the aforementioned surveying and marking method requires fine-tuning to ensure the drone hovers precisely above the point to be marked; otherwise, significant errors will occur in the marking position. However, precisely controlling the drone's position during fine-tuning is difficult, often resulting in over-adjustment and an inability to achieve accurate marking. Summary of the Invention

[0004] This application provides a surveying and mapping method, apparatus, device, and storage medium, which solves the problem in related technologies where the drone needs to be fine-tuned to be positioned directly above the mapping location, resulting in inaccurate mapping. This improves the accuracy and efficiency of surveying and mapping.

[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The surveying and mapping method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0034] The mapping and marking method provided in this solution, for example, is applicable when controlling an unmanned device to fly to the vicinity of the point to be marked. It utilizes the auxiliary operation points displayed on the terminal device's display interface provided in this solution to assist in mapping and marking the point, without requiring the unmanned device to be precisely positioned directly above the point to be marked.

[0035] Figure 1 The flowchart illustrates a surveying and mapping method provided in this application embodiment. This method can be executed by a terminal device, which may optionally be a smartphone, a remote control with a display screen, etc. Specifically, it includes the following steps:

[0036] Step S101: Display the device location point of the unmanned device and the target point to be surveyed and marked on the display interface of the terminal device. The geographical locations of the device location point and the target point are different.

[0037] In one embodiment, the terminal device's display interface can display the real-time footage captured by the camera of the unmanned device, such as the footage captured by the camera located below the unmanned device, which can be a drone.

[0038] Optionally, the terminal device displays images of the device's location and the target point to be surveyed in the captured image on its screen. The device location is a virtual point directly below the unmanned device displayed on the screen. For example, it can be displayed as a crosshair, such as a green dot with a crosshair, or, for example, the center point of the captured image. The target point is a virtual point corresponding to the location to be surveyed, such as a boundary of a plot of land or the location of obstacles. This target point is displayed in a different way than the device location, such as a red dot. Optionally, the target point can be a point identified through image recognition that needs to be surveyed. Figure 2 This is a schematic diagram of a first display interface of a terminal device provided in an embodiment of this application, as shown below. Figure 2 As shown, the display interface 01 displays a device location point 02 and a target point 03. The device location point 02 is a virtual point corresponding to the location directly below the unmanned device, and the target point is a virtual point corresponding to the location of the point to be surveyed and marked. The device location point 02 and the target point 03 correspond to different geographical locations. If they are the same, marking can be performed directly to complete the surveying and marking of the target point.

[0039] Step S102: When the auxiliary dot mode is triggered, the auxiliary operation points are displayed on the display interface.

[0040] In one embodiment, the terminal device integrates an auxiliary point marking function. For example, clicking the auxiliary point marking button on the display interface triggers the corresponding auxiliary point marking mode. In the auxiliary point marking mode, the display interface will show auxiliary operation points, which are used to assist in the mapping and marking of target points.

[0041] Optionally, the auxiliary operation points can be displayed in various forms, with different graphic displays in different auxiliary point-marking modes. For example, assuming the terminal device currently has two auxiliary point-marking modes, they can be referred to as the first auxiliary point-marking mode and the second auxiliary point-marking mode, respectively. Optionally, the first auxiliary point-marking mode can be the default triggered auxiliary point-marking mode. Optionally, the displayed auxiliary operation points are shown in a form distinct from device location points and target points, such as displayed as yellow dots.

[0042] Step S103: If the auxiliary operation point overlaps with the target point, calculate the geographical location of the target point based on the auxiliary operation point and the device location point to complete the mapping and marking of the target point.

[0043] In one embodiment, some of the displayed auxiliary operation points overlap with the target point, while others do not. When an auxiliary operation point overlaps with the target point, the overlapping auxiliary operation point can be directly selected, exemplarily denoted as the target auxiliary operation point. Optionally, the target auxiliary operation point can be selected by determining the target auxiliary operation point from multiple auxiliary operation points in response to an auxiliary point selection operation, or by using image recognition technology to determine the auxiliary operation point overlapping with the target point as the target auxiliary operation point.

[0044] In another embodiment, if the displayed auxiliary operation point does not overlap with the target point, it needs to be processed to create an auxiliary operation point that overlaps with the target point for subsequent calculation of the target point's geographical location. Optionally, the auxiliary operation point, as an operation control, can be processed by various operations such as dragging and selecting. After the auxiliary operation point is displayed, the user can process it to overlap with the target point, such as dragging the auxiliary operation point to the position where the target point is displayed.

[0045] In one embodiment, when the auxiliary operation point and the target point overlap, the geographical location of the target point is calculated based on the overlapping auxiliary operation point and the device location point. Optionally, during the calculation process, the geographical offset distance between the auxiliary operation point and the device location point is calculated, and then the final geographical location of the target point is obtained based on this geographical offset distance and the geographical location of the device location point. Since the device location point is directly below the unmanned device, its geographical location shares the same latitude and longitude as the unmanned device's geographical location. When calculating the geographical offset distance between the auxiliary operation point and the device location point, the offset angle can be determined based on the location point of the auxiliary operation point projected onto the ground and the device location point, and then the geographical offset distance between the auxiliary operation point and the device location point can be calculated based on the drone's altitude and this offset angle. For example, as shown... Figure 3 As shown, Figure 3 This illustration provides a method for calculating the geographical offset distance of an auxiliary operation point relative to a device location point, as provided in this application embodiment. The drone's altitude *c* can be obtained from the flight parameters transmitted back by the drone. Location point 1 is the position directly below the drone, and location point 2 is the location point projected onto the ground by the auxiliary operation point. The angle α can be obtained using the drone's integrated field-of-view calculation function. The geographical offset distance *b* of location point 2 relative to location point 1 is then calculated as *c*tanα. Optionally, after obtaining the geographical offset distance of location point 2 relative to location point 1, the orientation of the auxiliary operation point relative to the device location point can be determined from the display interface. Based on this orientation and the geographical offset distance, the corresponding latitude and longitude coordinates can be converted to obtain the actual geographical location of the auxiliary coordinate point, i.e., the target point.

[0046] As described above, when using unmanned equipment for surveying and mapping, the device's location and the target point to be surveyed are displayed on the terminal device's screen. When the auxiliary mapping mode is triggered, auxiliary operation points are displayed on the screen. If the auxiliary operation points overlap with the target point, the geographical location of the target point is calculated based on the auxiliary operation points and the device's location, thus completing the surveying and mapping of the target point. This surveying and mapping method eliminates the need to position the unmanned equipment directly above the target point; it achieves mapping through the auxiliary operation points displayed on the screen, improving surveying and mapping efficiency, enabling rapid mapping, and ensuring mapping accuracy.

[0047] Figure 4 A flowchart of another surveying and mapping method provided in the embodiments of this application is shown below. Figure 4 As shown, it specifically includes:

[0048] Step S201: Display the device location point of the unmanned device and the target point to be surveyed and marked on the display interface of the terminal device. The geographical locations of the device location point and the target point are different.

[0049] Step S202: When the first auxiliary dot mode is triggered, multiple auxiliary operation points are displayed on the display interface.

[0050] For example, such as Figure 5 The above, Figure 5 This is a schematic diagram illustrating a first auxiliary dot-mapping mode provided in an embodiment of this application. After the first auxiliary dot-mapping mode is triggered, multiple auxiliary operation points are displayed on the display interface. Optionally, it can be... Figure 5 The example shown displays a preset number (8) of auxiliary operation points in different locations, centered on the device's location.

[0051] Step S203: In the case where the auxiliary operation point and the target point overlap, in response to the auxiliary point selection operation, a target auxiliary operation point is determined among the plurality of auxiliary operation points, and the geographical location of the target point is calculated based on the target auxiliary operation point and the device location point.

[0052] Optionally, after displaying multiple auxiliary operation points, each of these auxiliary operation points can be selected accordingly, such as... Figure 5 In the example shown, the target point overlaps with auxiliary operation point 3. That is, the location of auxiliary operation point 3 can represent the location of the target point. Auxiliary operation point 3 serves as the target auxiliary operation point, and the user can select it. Optionally, the selection method can be to display eight numbers at a time on the display interface, and the user can click on one of the numbers to select the corresponding auxiliary operation point with the same number. Once auxiliary operation point 3 is selected, it will be used for subsequent target point calculations.

[0053] As described above, when marking target points, multiple auxiliary operation points are displayed on the interface. In response to an auxiliary point selection operation, the selected auxiliary operation point is determined from among these points to calculate the geographical location of the target point. This method of marking target points eliminates the need to control unmanned equipment to move above the target point. By displaying auxiliary operation points and utilizing them to perform target point calculations, the accuracy and efficiency of surveying and marking are improved.

[0054] Figure 6 A flowchart of another surveying and mapping method provided in the embodiments of this application is shown below. Figure 6 As shown, it specifically includes:

[0055] Step S301: Display the device location point of the unmanned device and the target point to be surveyed and marked on the display interface of the terminal device. The geographical locations of the device location point and the target point are different.

[0056] Step S302: When the first auxiliary dot mode is triggered, multiple auxiliary operation points are displayed on the display interface.

[0057] Step S303: If the auxiliary operation point and the target point do not overlap, in response to the scale adjustment operation, the positions of the plurality of auxiliary operation points are adjusted so that there is a target auxiliary operation point among the plurality of auxiliary operation points that overlaps with the target point.

[0058] In one embodiment, if none of the displayed auxiliary operation points overlap with the target point, the scale can be adjusted accordingly to change the positions of multiple auxiliary operation points. For example, such as... Figure 7 As shown, Figure 7 This is a schematic diagram of another first auxiliary dot-marking mode provided in an embodiment of this application. In this mode, the target point 03 does not overlap with any auxiliary operation point. The position of the auxiliary operation point can be changed by adjusting the scale 04. Optionally, by enlarging the scale, the distance between the auxiliary operation point 3 and the device position point can be proportionally enlarged. When the auxiliary operation point 3 overlaps with the target point 03, it can be used for dot-marking operations.

[0059] Step S304: In response to the auxiliary point selection operation, determine the selected target auxiliary operation point among the plurality of auxiliary operation points, and calculate the geographical location of the target point based on the target auxiliary operation point and the device location point.

[0060] As described above, when marking target points, multiple auxiliary operation points are displayed on the screen. By adjusting the scale so that the target point overlaps with one of the auxiliary operation points, the geographical location of the target point is calculated based on the overlapping auxiliary operation point. Through simple interface operation, there is no need to control the unmanned equipment to make precise position adjustments, saving control operation time and avoiding the problem of inaccurate marking due to inconvenient operation.

[0061] Figure 8 A flowchart of another surveying and mapping method provided in the embodiments of this application is shown below. Figure 8 As shown, it specifically includes:

[0062] Step S401: Display the device location point of the unmanned device and the target point to be surveyed and marked on the display interface of the terminal device. The geographical locations of the device location point and the target point are different.

[0063] Step S402: When the second auxiliary dot mode is triggered, the auxiliary operation point with directional indicator mark is displayed in the display interface.

[0064] For example, such as Figure 9 As shown, Figure 9 This is a first schematic diagram of a second auxiliary point marking mode provided in an embodiment of this application. In this second auxiliary point marking mode, auxiliary operation points with directional indicator marks are displayed. At the same time, the user can control the movement of the auxiliary operation points to make them coincide with the target point by clicking the direction button 05 displayed on the display interface.

[0065] Step S403: If the auxiliary operation point and the target point do not overlap, in response to the auxiliary point movement operation, control the auxiliary operation point to move in the display interface so that it overlaps with the target point. If the auxiliary operation point and the target point overlap, calculate the geographical location of the target point based on the auxiliary operation point and the device location point to complete the mapping and marking of the target point.

[0066] In one embodiment, a dot-marking button can be displayed on the interface. When the auxiliary operation point and the target point overlap, clicking the dot-marking button allows the geographical location of the target point to be calculated based on the auxiliary operation point and the device location point, thus completing the mapping and marking of the target point. For example, as shown... Figure 10 As shown, Figure 10 This is a second schematic diagram of a second auxiliary dotting mode provided in an embodiment of this application. As can be seen from the figure, the auxiliary operation point overlaps with the target point after being moved, and can be used for subsequent dotting processing.

[0067] As can be seen from the above, when marking target points, auxiliary operation points with directional indicators are displayed on the display interface. Through simple interface operation, there is no need to control the unmanned equipment to make precise position adjustments, which saves control operation time and avoids the problem of inaccurate marking due to inconvenient operation.
