All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In the following embodiments, optional features and examples are provided in each embodiment, and various features described in the embodiments may be combined to form a plurality of alternatives, and each numbered embodiment should not be regarded as only one technical solution.

Example one

Fig. 1 is a flowchart illustrating a distance measuring method according to an embodiment of the present invention, where the distance measuring method according to the embodiment of the present invention is applicable to a case of measuring a distance, for example, a case of measuring a required distance before purchasing a commodity by using a shopping application. The method may be performed by a distance measuring device implemented in software and/or hardware, preferably configured in an electronic device, such as a mobile phone. As shown in fig. 1, the distance measuring method provided in the embodiment of the present invention includes the following steps:

s110, acquiring the equipment identifier of the mobile terminal equipment, and uploading the equipment identifier to a server so that the server can inquire equipment size data and an equipment model diagram corresponding to the equipment identifier.

In the embodiment of the invention, the mobile terminal equipment is mobile phone, notebook or tablet computer and other terminal equipment which is widely used for life and work of users and is convenient to move. When a user needs to measure the distance and finds standard measuring tools such as a ruler and the like at hand, the distance can be measured by replacing the ruler with mobile terminal equipment such as a mobile phone or a tablet personal computer and the like. Before distance measurement is performed, the device identifier of the mobile terminal device serving as the ruler may be uploaded to a server supporting the distance measurement service provided in this embodiment, so that the server performs fast retrieval and query through locally cached data, or queries device information corresponding to the device identifier through the internet or other manners, where the device information includes, but is not limited to, device size data, a device model diagram, or a device default screen saver cover diagram.

In this embodiment, the device identifier may be, for example, a device name, a device model, or the like, which is used to determine a unique device shape; the device dimension data is the overall dimension of the device, such as the actual dimension data of the device, such as the length, width and thickness of the device; the equipment model diagram is an appearance diagram of the equipment, the equipment model diagram can be a two-dimensional or three-dimensional model diagram, the measurement requirement can be met by selecting the two-dimensional model diagram as the measured distance is one-dimensional data, and the equipment model diagram is more beneficial to the operations of transmission, storage, rendering and the like. The default screen saver cover map of the equipment can improve the rendering effect of the equipment model map when the equipment model map is rendered on the current interface, and the distance measurement experience of a user can be improved.

Optionally, obtaining the device identifier of the mobile terminal device includes: responding to the selection operation of the items in the drop-down box control in the current interface, and taking the selected items as the equipment identification of the mobile terminal equipment; or, the device identifier of the current mobile terminal device is obtained by calling the system native program of the current mobile terminal device.

In this embodiment, the mobile terminal device may be a current mobile terminal device running the program code corresponding to the distance measuring method, and may be another mobile terminal device not installed or running the program code corresponding to the distance measuring method. For example, a user has two mobile terminal devices, namely a mobile phone and a tablet computer, and currently uses the tablet computer to operate a program code corresponding to the distance measurement method, but the mobile phone may be used to replace a ruler for distance measurement, and the tablet computer may also be used to replace the ruler for distance measurement.

When the user selects to use the non-current mobile terminal device to replace the ruler for distance measurement, the user can click an entry in a pull-down box control rendered in the current interface to perform an entry selection operation, wherein each entry in the pull-down box control is the device identifier of each mobile terminal device. And the current mobile terminal equipment responds to the selection operation of the item, and takes the item selected by the user as the equipment identification of the mobile terminal equipment. In addition, if the device identifier that the user wants to select does not exist in the entry, an "other" entry may be set in the drop-down box control, so that the user may pop up a text box control by clicking the "other" entry, and the user may manually input the device identifier of the mobile terminal device in the text box control.

In addition, the current mobile terminal device may default to the user selecting a distance measurement with the current mobile terminal device instead of a ruler before the user selects an entry from the drop-down box control. At this time, the current mobile terminal device may call a system native program (native program) on the bottom layer to obtain the device identifier of the current mobile terminal device, and then may automatically select a corresponding entry in the drop-down box control according to the obtained device identifier to display, so as to automatically achieve device identifier acquisition and improve ranging efficiency.

And S120, receiving the equipment size data and the equipment model diagram, rendering the equipment model diagram in the current interface, and establishing a mapping relation between the rendered equipment model diagram and the equipment size data.

In the embodiment of the invention, after inquiring the equipment size data and the equipment model diagram corresponding to the equipment identifier, the server can feed back the current equipment corresponding to the program code of the running distance measuring method through the corresponding data issuing interface. The current device may store the received device size data for subsequent ranging, and may render the received device model map in the current interface so that the user may see the simulated model map of the mobile terminal device in place of the ruler.

The device model map can be rendered at a preset position of a current interface of the current device, such as a central position of the interface. The image size of the rendered device model image may be different from the original size of the received device model image, and a mapping relation can be established between the image size of the rendered device model image and the device size data, so that a foundation is laid for subsequent ranging.

Illustratively, the rendered device model map is a front two-dimensional model map of a mobile phone, the rendered mobile phone is 1700 pixels long, and the real mobile phone in the device size data is 15cm long, then a corresponding relationship between the 1700 pixels and 15cm can be established, that is, each pixel can correspond to an actual distance of 15/1700 cm.

Optionally, rendering the device model map in the current interface includes: acquiring the screen size of the current equipment, and determining the scaling of the equipment model diagram according to the screen size and the picture size of the equipment model diagram; determining layout parameters of the picture display control according to the picture size and the scaling; rendering the picture display control in the current interface according to the layout parameters of the picture display control, and importing the equipment model picture which is scaled according to the scaling into the picture display control for displaying.

The device model graph can be subjected to size adaptive rendering according to the screen size of the current device, and the situation that the rendering of the device model graph is too large or too small and is not beneficial to a user to input the starting point position and the ending point position is avoided. The current equipment can also call a native program to obtain the screen size; further, the optimal scaling of the device model map can be determined according to the preset area proportion of the device model map expected to be rendered occupying the current screen and the picture size of the device model map; according to the scaling, the picture size of the device model graph during rendering can be determined, and the picture size during rendering can be used as the size of the height and the width of the picture display control; if the equipment model graph is expected to be rendered at the central position of the current interface, the position coordinates of the central point of the picture display control can be determined, the height, the width and the position coordinates of the central point of the picture display control can be used as layout parameters of the picture display control, the picture display control is generated on the current interface according to the layout parameters, and meanwhile, the scaled equipment model graph can be led into the generated picture display control to be rendered to obtain an equipment model graph, so that the equipment model graph is displayed on the current interface.

S130, receiving a starting point position and an end point position which act on the rendered device model diagram for at least one time, determining an actual distance between the starting point position and the end point position according to the mapping relation, and determining a required distance according to at least one actual distance.

In the embodiment of the present invention, after measuring a required distance using a real mobile terminal device, a user may input a start position and an end position in a device model map corresponding to a measurement start point and a measurement end point in a real measurement process from a device model map rendered by a current device, for example, sequentially click the start position and the end position in the rendered device model map. After the user inputs the start point position and the end point position, the current device may identify the start point position and the end point position input by the user in the current interface (for example, identify the start point position and the end point position input by the user with a circle dot), and may perform operations such as deleting or moving the start point position and the end point position according to an editing instruction input by the user.

When a user uses a real mobile terminal device to measure a required distance, the required distance may be smaller than or equal to the device size data of the mobile terminal device, and may also be larger than the device size data of the mobile terminal device. When the required distance is smaller than or equal to the device size data of the mobile terminal device, the required distance is measured once by using the mobile terminal device, at this time, the user can input the starting point position and the end point position once on the rendered device model diagram, and the current device can take the received actual distance between the starting point position and the end point position input this time as the required distance. When the required distance is greater than the device size data of the mobile terminal device, the required distance can be obtained only by measuring the required distance twice by using the mobile terminal device, at this time, a user can input a starting point position and an end point position on the rendered device model diagram for multiple times, the current device can respectively determine the actual distance between the starting point position and the end point position input each time, and the sum of at least one determined actual distance can be used as the required distance.

The current device can determine the actual distance between the starting point position and the end point position on the device model diagram according to the mapping relation between the device model diagram rendered in the current interface and the device size data when the user inputs the instructions of the starting point position and the end point position each time. The current device can also determine the required distance according to each actual distance when the user inputs the starting position and the end position, and can also import the determined required distance into a rendered text box control used for displaying the required distance in the interface so that the user can know the numerical value of the measured required distance.

The method comprises the steps of rendering an equipment model diagram with the same appearance as that of mobile terminal equipment used for distance measurement on an interface of the current equipment, inputting a start/end point position corresponding to an actually measured start/end point position on the rendered equipment model diagram, and obtaining the distance between the actually measured start/end point positions based on the mapping relation between the equipment model diagram and equipment size data, so that the required distance measurement is realized by utilizing the interface with the measurement function.

Optionally, after receiving the device size data and the device model map, the method further includes: storing the equipment size data and the equipment model diagram, and establishing a corresponding relation between the equipment identification and the equipment size data and the equipment model diagram;

correspondingly, after acquiring the new device identifier, the method further includes: judging whether the corresponding relation has equipment size data and an equipment model diagram corresponding to the new equipment identification; if so, reading the equipment size data and the equipment model diagram corresponding to the new equipment identification; rendering the read equipment model diagram in a current interface, and establishing a mapping relation between the rendered equipment model diagram and the read equipment size data; and if not, uploading the new equipment identifier to the server.

In this embodiment, after receiving the device size data and the device model map fed back by the server, the current device may store the device size data and the device model map in a local storage space, and establish a correspondence between the device identifier and the device size data and the device model map. For example, the current device may establish an identification-data model library in which the device identification, the device size data, and the device model map may be recorded, and may establish correspondence between the device identification and the device size data and the device model map.

If the current equipment is used for ranging again, after the equipment identifier is obtained, whether the equipment size data and the equipment model diagram corresponding to the equipment identifier exist in the established corresponding relation can be judged. If the device size data and the device model diagram exist, the corresponding device size data and the device model diagram can be read from the local storage space very quickly, and the read device model diagram is rendered in the current interface, so that the rendering efficiency of the device model diagram is improved, and better experience is provided for a user; and establishing a mapping relation between the rendered device model diagram and the read device size data for subsequent distance measurement. If the device size data does not exist, the device identifier can be sent to the server, so that the server inquires device size data and a device model diagram corresponding to the device identifier; and after receiving the device size data and the device model diagram fed back by the server, the received device size data and the received device model diagram can be stored again, and the corresponding relation between the device identifier and the device size data and the device model diagram is established, so that the locally stored corresponding relation is enriched.

For example, the received device size data, the device model map and the device identifier may be added to the identifier-data model library, and a corresponding relationship between the device identifier and the device size data and the device model map is established to update the identifier-data model library, which is beneficial for the current mobile terminal device to locally obtain the device size data and the device model map.

According to the distance measuring method provided by the embodiment of the invention, the current equipment acquires the equipment identifier of the mobile terminal equipment for distance measurement and uploads the equipment identifier to the server so that the server inquires equipment size data and an equipment model diagram corresponding to the equipment identifier; the current equipment receives equipment size data and an equipment model diagram which are inquired by a server and correspond to the equipment identification, renders the equipment model diagram in a current interface, and establishes a mapping relation between the rendered equipment model diagram and the equipment size data; the current device receives a starting position and an end position which act on the rendered device model diagram at least once, determines an actual distance between the starting position and the end position according to the mapping relation, and can determine a required distance according to the actual distance. The method comprises the steps of rendering an equipment model diagram of the mobile terminal equipment for ranging on an interface, inputting a starting/ending point position corresponding to the starting/ending point position actually measured at least once on the rendered equipment model diagram, obtaining the distance between at least one actually measured starting/ending point position based on the mapping relation between the equipment model diagram and equipment size data, and obtaining the size of a required distance according to at least one actual distance.

Example two

On the basis of the embodiment, the interface rendering and distance measuring steps are optimized, the distance measuring range can be expanded, and the user experience is improved. The present embodiment is the same inventive concept as the distance measuring method proposed in the above embodiments, and reference may be made to the above embodiments for technical details that are not described in detail in the present embodiment.

Fig. 2 shows a flowchart of a distance measuring method according to a second embodiment of the present invention. Referring to fig. 2, a distance measuring method provided in an embodiment of the present invention includes:

s210, acquiring the equipment identifier of the mobile terminal equipment, and uploading the equipment identifier to a server so that the server queries equipment size data and an equipment model diagram corresponding to the equipment identifier.

S220, receiving the equipment size data and the equipment model diagram, rendering the equipment model diagram in the current interface, and establishing a mapping relation between the rendered equipment model diagram and the equipment size data.

And S230, responding to the received measurement dimension, determining first dimension data corresponding to the measurement dimension in the device dimension data, and rendering the slider control corresponding to the measurement dimension in the rendered device model diagram in the current interface.

In this embodiment, the current device may receive user input of the measurement dimension to determine the measurement edge for measurement in the mobile terminal device. In addition, if the current device does not receive the measurement dimension input by the user, a default dimension (for example, a long edge in the model map) in the device model map may also be used as the measurement dimension.

After determining the measurement edge dimension for measurement, the current device may extract, from the device size data, size data of a measurement edge corresponding to the measurement dimension in the real mobile terminal device, that is, first size data corresponding to the measurement dimension. The rendering of the slider control corresponding to the measurement dimension may specifically be rendering the slider control outside the measurement edge corresponding to the measurement dimension in the device model map. Moreover, a corresponding relationship can be established between the pixel position of each pixel point of the slide rail in the slider control and the pixel position of the pixel point of the measurement edge in the device model diagram, for example, the length of the measurement edge in the device model diagram is 1700 pixels, and the length of the slide rail is 850 pixels, so that a corresponding relationship can be established between one pixel point of the slide rail and two pixel points of the measurement edge in the device model diagram, and when the slide rail slides for one pixel position, the corresponding measurement position input on the measurement edge in the device model diagram moves for two pixel positions.

And S240, responding to the received first coefficient, and calculating the product of the first coefficient and the first size data to obtain a first distance.

In this embodiment, when the measurement edge of the real mobile terminal device is used to measure the required distance, and the required distance is greater than the length of the measurement edge, the value of the required distance may be determined in a form of adding several times of the measurement edge to the starting position to the ending position on the remaining measurement edges, and the first coefficient may represent a positive integer multiple of the size data of the measurement edge in the real mobile terminal device. The multiple length of the measuring edge of the real mobile terminal equipment in the required distance, namely the first distance, can be obtained by calculating the product of the first coefficient and the first size value. In addition, when the required distance is less than or equal to the length of the measurement edge, the first coefficient may also have a value of zero.

By receiving the first coefficient, the operation that a user inputs the starting position and the end position on the rendered equipment model graph for many times is avoided, the measurement operation steps are simplified, and the distance measurement efficiency and the user experience are improved.

And S250, responding to the sliding operation of the slider in the slider control, and determining a sliding starting point and a sliding end point.

In this embodiment, the remaining distance in the required distance, which is not the multiple length of the measurement edge of the real mobile terminal device, may be correspondingly represented by the range from the sliding start point to the sliding end point of the slider in the slider control. Due to the fact that the corresponding relation is established between the position of the sliding block and the position on the measurement dimension in the rendered device model graph, the current device can determine the starting point position and the end point position acting on the rendered device model graph according to the sliding starting point and the sliding end point.

For example, if the remaining distance in the real measurement is a range in the middle of the measurement edge in the real mobile terminal device, in response to the sliding operation of the slider in the slider control, the sliding start point and the sliding end point may be determined by taking the slider position input by the user clicking the slide rail for the first time as the sliding start point, taking the slider position input by the user clicking the slide rail for the second time as the sliding end point, or taking the slider position where the user presses the slider from the sliding start point until the user stops pressing the slider as the sliding end point.

For another example, if the remaining distance during the actual measurement is a range measured from the corresponding end of the initial end of the slider while the measurement is performed in the actual mobile terminal device, determining the sliding start point and the sliding end point may be, in response to the sliding operation of the slider in the slider control, using the initial end of the slider in the slider control as the sliding start point, and using the slider position input by the user clicking the slide rail as the sliding end point, or using the slider position where the user presses the slider from the sliding start point until the user stops pressing the slider as the sliding end point.

And S260, determining the actual distance from the sliding starting point to the sliding end point according to the corresponding relation between the position of the sliding block and the position on the measurement dimension in the rendered equipment model diagram and the mapping relation.

The corresponding relation between the position of the slider and the position on the measurement dimension in the rendered equipment model graph can be regarded as the pixel position of the pixel point on the slide rail where the slider is located, and the corresponding relation between the pixel position of the pixel point on the measurement edge in the equipment model graph, and the number of the pixel points on the measurement edge in the rendered equipment model graph corresponding to the sliding starting point to the sliding ending point can be determined according to the corresponding relation. Further, according to the mapping relationship between the rendered device model diagram and the device size data, the value of the actual remaining distance corresponding to the number of the pixel points on the measuring side in the rendered device model diagram, namely the actual distance, can be determined.

And S270, taking the sum of the first distance and the actual distance as a required distance.

In the embodiment of the invention, the value of the required distance can be determined by the way of adding the value of the multiple length of the measuring edge and the value of the starting position to the end position on the rest measuring edge when the required distance is greater than the length of the measuring edge by summing the first distance and the actual distance, thereby simplifying the measuring operation steps and improving the distance measuring efficiency and the user experience.

Optionally, rendering a slider control corresponding to a measurement dimension in the rendered device model diagram in the current interface, including: determining a side length parameter and a position parameter corresponding to a measurement dimension in a picture display control introduced by a rendered equipment model diagram; translating the position parameter by a preset value along a direction perpendicular to the measurement dimension and far away from the rendered equipment model diagram to obtain a target position parameter; and taking the side length parameter and the target position parameter as layout parameters of the slider control, and rendering the slider control in the current interface according to the layout parameters of the slider control.

In this embodiment, the side length parameter and the position parameter corresponding to the measurement dimension in the picture display control imported from the rendered device model map may be regarded as the pixel length of the measurement side corresponding to the measurement dimension in the rendered device model map and the pixel position coordinates of the end points on either side of the measurement side.

The position parameter is translated by a preset value along a direction perpendicular to the measurement dimension and away from the rendered device model diagram, so that the pixel position coordinates of the end points on any side of the slide rail in the slider control outside the measurement edge, that is, the target position parameter, can be obtained, wherein the preset value can be set according to the screen size of the current device, for example, can be set to 100 pixels or 150 pixels, and is not specifically limited herein.

The side length parameter of the measured edge is used as the side length parameter of the slide rail in the slide block control, and the slide block control with the same length as the measured edge in the equipment model drawing can be rendered outside the measured edge according to the pixel position coordinates of the end points on any side of the slide rail in the slide block control. By rendering the slider control with the same length as that in the equipment model diagram, the input sliding starting point and sliding end point can be completely corresponding to the starting point position and the end point position on the measuring edge in the equipment model diagram, and the measuring precision is improved to a certain extent.

On the basis of the embodiment, the current equipment can determine the measuring edge used for measuring in the mobile terminal equipment according to the measuring dimension input by the user, and can input a first coefficient used for expressing the multiple of the measuring edge; the outer side of the measuring edge can be rendered with a corresponding slide block control, and the starting point position and the end point position of the remaining distance except the distance of the measuring edge length multiple can be input through the slide block; and finally, the measured actual distance is the actual distance which is greater than the length of the measuring edge by multiplying the first size data of the measuring edge by a first coefficient and adding the distance between the sliding starting point and the sliding ending point of the sliding block.

In one embodiment, the rendered slider control may preferably be as long as the measurement edge, so that the exact correspondence between the input sliding start and end points and the start and end points on the measurement edge in the device model map improves the measurement accuracy to some extent. In addition, the embodiment of the present invention and the distance measuring method proposed by the above embodiment belong to the same inventive concept, and technical details that are not described in detail in the embodiment can be referred to the above embodiment, and the embodiment has the same beneficial effects as the above embodiment.

EXAMPLE III

On the basis of the embodiment, the distance measurement is optimized when the method is applied to a shopping application scene, the required distance can be measured before shopping, commodities with proper sizes can be automatically recommended according to the measured actual distance, and the user experience is further improved. The present embodiment is the same inventive concept as the distance measuring method proposed in the above embodiments, and reference may be made to the above embodiments for technical details that are not described in detail in the present embodiment.

Fig. 3 shows a flowchart of a distance measuring method according to a third embodiment of the present invention. Referring to fig. 3, a distance measuring method provided in an embodiment of the present invention includes:

s310, responding to the measurement instruction, switching the shopping interface to the measurement interface, and taking the measurement interface as the current interface.

When a user purchases commodities on line by using the traditional shopping application, the shopping application can render a shopping interface according to commodity detail data issued by the server so that the user can know various parameters such as the size, the color or the structure of the commodities. Although the interface presents the size of the commodity, the user cannot know whether the size of the commodity is matched with the required distance, the size of the purchased commodity is not proper easily, the situation that the commodity needs to be returned after receiving the commodity is found, the commodity returning not only increases the purchase cost such as freight charge or damage payment, but also prolongs the time for receiving the required commodity. In addition, when the goods are sold in a limited amount/limited time, the required size cannot be changed, and the shopping experience is greatly influenced.

In this embodiment, in the process of shopping by using the shopping application, when browsing a shopping interface corresponding to a certain commodity, a user may trigger a measurement instruction on the shopping interface. After the current device receives the measurement instruction, the shopping interface can be switched to the measurement interface, and the measurement of the required distance is realized by rendering a device model diagram and other controls for measurement on the measurement interface.

For example, a user may enter a shopping interface for a particular item by clicking on an introduction cover for the item, where the shopping interface may include at least one item introduction map, item title introduction, shipping address, item parameters, selection, and a ranging function. When the user clicks the 'selection' list item, shopping interfaces such as the shopping types, the sizes and the quantities of commodities and the like can be popped up. Before entering the shopping interface to select the size, the user can click the list item of the distance measuring function to trigger a measuring instruction, so that the current equipment is switched to the measuring interface from the shopping interface.
