Description

Deformation measurement method and detection device Technical Field The present application relates to the field of deformation measurement technology, and more particularly, to a deformation measurement method and a detection device. Background At present, deformation measurement can be performed by using a general sense integrated base station, however, the general sense integrated base station has the problem of shaking of a base station antenna feeder, and the accuracy of deformation measurement is seriously affected. For the problem, IMU (inertialmeasurementunit) sensors can be used for measuring the shake displacement of the antenna feeder, so that the shake of the antenna feeder is calibrated, but the measurement requirement of sub-millimeter precision cannot be met due to the limited measurement precision of the IMU sensors. Or the camera arranged on the deformation measuring platform is used for collecting image data, so that the shaking displacement of the platform is calibrated, but the image data collected by the camera needs to be carried out under higher meteorological conditions, so that the requirement of measuring precision can not be met under some severe conditions. Based on the above, how to calibrate the antenna feed and shake to improve the accuracy of deformation measurement of the universal base station becomes a problem to be solved. Disclosure of Invention The application provides a deformation measurement method and a detection device, and further the method can be understood as an optimized deformation measurement method, and the method can estimate and compensate the shaking amplitude of the detection device when the deformation measurement is carried out, so that the accuracy of the deformation measurement is improved. In a first aspect, a method of deformation measurement is provided, which may be applied to a detection apparatus, which may be a detection device, or which may be a unit/module/component (e.g. a chip or a system of chips or a logic circuit or software) configured in (or for) a detection device. The detection device is, for example, a communication-sensing integrated base station or a device capable of transmitting electromagnetic wave signals, such as a radar mounted on an iron tower or a pole, and is described below by taking the communication-sensing integrated base station (simply referred to as a base station) as an example. The method comprises the steps of acquiring a first carrier phase of a plurality of reference points based on position information of the plurality of reference points and acquiring a first carrier phase of a to-be-measured point based on position information of the to-be-measured point when the antenna feeder is located at a first position, acquiring a second carrier phase of the plurality of reference points based on position information of the plurality of reference points and acquiring a second carrier phase of the to-be-measured point based on position information of the to-be-measured point when the antenna feeder is located at a second position, determining displacement (namely, antenna feed shake displacement) between the first position and the second position based on the position information of the plurality of reference points, and determining antenna feed shake phase of the to-be-measured point based on the displacement between the first position and the second position and the position information of the to-be-measured point, wherein the antenna feed shake phase of the to-be-measured point refers to phase change generated by movement of the first position to the second position, and determining phase change of the to-be-measured point due to deformation based on the first carrier phase of the to be-measured point, the second carrier phase of the to be-measured point, and the antenna feed shake phase of the to be-measured point. Optionally, the method further comprises determining a first position of the antenna feeder, a plurality of reference points, and position information of the point to be measured. The first position of the antenna feeder refers to a position where the antenna feeder is located when the base station acquires the first carrier phases of the plurality of reference points and the first carrier phases of the points to be measured. The plurality of reference points are all points with unchanged absolute positions (or fixed absolute positions), so that whether the antenna feeder shakes or not can be determined by using the position information of the reference points. It should be appreciated that the position information of the reference point is unchanged relative to the measurement object (e.g., an antenna feeder), and that the position information of the reference point may change from measurement object to measurement object when the same reference point is used to measure different measurement objects. Based on the scheme, the plurality of reference points are all points with unchanged absolute positio
