Abstract

The present disclosure provides a method, system, medium, and equipment for identifying and step-by-step enhancement of the boundary of deep anomalies. According to the three-component data of the magnetic field and the magnetic gradient tensor data of the object to be identified, the boundary of the deep anomaly is obtained through arctangent operation. Preliminary recognition results; use the magnetic gradient tensor data component, and use the arctangent operation to improve the boundary recognition method to suppress the deformation of the deep abnormal body boundary; use the idea of ​​​​gamma transformation in image processing, and selectively enhance according to different values The contrast of the shadow area or the contrast of the highlight area, the image enhancement with adjustable parameters, further highlights the boundary of the target body, and obtains the final recognition result.

Description

technical field [0001] The disclosure belongs to the field of image processing, and specifically relates to a method, system, medium and equipment for identifying and step-by-step enhancement of boundaries of deep abnormal bodies. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Boundary recognition technology based on magnetic gradient tensor data is widely used in military or civilian applications, such as underground unexploded ordnance detection and mineral resource exploration. The magnetic gradient tensor data is the gradient of the magnetic field vector component, which has the advantages of multiple parameters, strong anti-interference ability, and high resolution, and can describe various information of anomalous bodies more abundantly and accurately. Boundary identification is an important task in the interpretation of potentia...
