Embodiment 1

[0048] like figure 1 As shown, in one embodiment of the detection data mileage registration method, including steps:

[0049] S100, obtains the data to be registered, generates a pattern to be registered according to the to-registration data, wherein the to-bearing data includes a plurality of miles and detection data corresponding to each mileage location.

[0050] The data to be registered is data obtained after detecting the target structure, such as after detecting the current structure, outputting the to-registration data, including multiple mileage locations and each mileage position The corresponding detection data can be represented as n-sequence points, each sequence point can be recorded (D i , f i ), Where D i Represents the i-th mileage, f i Indicates the detection data at the i-th mileage position, each sequence point can be seen as a coordinate point, and multiple sequence points can form a curve in order.

[0051] In a possible implementation, it may be that the resp...

Embodiment 2

[0090] Based on the above embodiment, the present invention also provides a detection data mileage registration device, such as Figure 5 As shown, the detection data mileage registration device includes:

[0091] Curve generation module, the curve generating module is used to obtain the data to be registered, and the to-bearing data is generated according to the to be registered, wherein the to be registered data includes a plurality of mileage locations and each mileage position. The detection data is specifically described in the embodiment;

[0092] The overlapping area determining module is configured to divide the to be registered into a plurality of curve segments, and the first target of the target curve segment in the plurality of curve segments and the preset reference curve. At least one second target point is aligned, obtaining at least one target overlap region of the target curve and the preset reference curve, as described in the first embodiment;

[0093] Offset det...

Embodiment 3

[0096] Based on the above embodiment, the present invention also provides a terminal, such as Image 6 As shown, the terminal includes a processor 10 and a memory 20. Image 6 Only some components of the terminal are shown, but it should be understood that all displayed components are not required to replace more or fewer components.

[0097] The memory 20 can be in some embodiments, the internal storage unit of the terminal, such as a hard disk or memory of the terminal. The memory 20 may also be an external storage device of the terminal, such as a plug-in hard disk, a smart media card, SMC, a secure number (SecureDigital, SD), secure digital, SD, SMART MEDIA CARD, SMC ) Card, flash card (Flash Card), etc. Further, the memory 20 can also include both internal storage units of the terminal also include an external storage device. The memory 20 is configured to store applications and various types of data mounted on the terminal. The memory 20 can also be used to temporarily store d...

Abstract

The invention discloses a detection data mileage registration method and device, a terminal and a storage medium, and the method comprises the steps: obtaining to-be-registered data, generating a to-be-registered curve according to the to-be-registered data, wherein the to-be-registered data comprise a plurality of mileage positions and detection data corresponding to each mileage position; dividing the curve to be registered into a plurality of curve segments, aligning a first target point of a target curve segment in the plurality of curve segments with at least one second target point of a preset reference curve, and obtaining at least one target overlapping region of the target curve segment and the preset reference curve; determining the offset of the target curve segment according to the correlation coefficient of each target overlapping region and the target curve segment; and obtaining a mileage correction curve according to the offset of each curve segment, and correcting the mileage position of each sampling point on the to-be-registered curve according to the mileage correction curve. According to the invention, the mileage position in the to-be-registered data and the mileage position in the reference data can be registered.

Description

Technical field [0001] The present invention relates to the field of detection, and in particular, to a detection data mileage registration method, apparatus, terminal, and storage medium. Background technique [0002] Highway detection, rail detection, pipe detection and other linear structural objects generally output detection data with mileage positions, such as test data at a 10km mileage location, in practice, may be collected in different periods The detection data is spatially associated, and the mileage position is an important basis for the spatial association of the linear structure detection data. In general, the detection system outputs the mileage position of each detection data, but due to the positioning error of the detection system, the mileage position collected in different periods, different methods is inconsistent, there is a deviation, which will result in different detection systems, different periods of collection. Detection data cannot be correlated. [...
