This disclosure relates generally to systems and methods for data acquisition and asset inspection in presence of magnetic interference. Data 830 acquisition and assets inspection systems in many infrastructures such as railway, power line, and bridges provide inaccurate results in presence of magnetic interference. The proposed system and method proposes UAV based navigation through a dynamic correction path to inspect one or more assets in one or more infrastructures. A plurality of sensors are integrated 835 with the UAV to acquire images of the one or more assets in presence of magnetic field. The acquired images are further processed to segment and detect anomalies in one or more parts of the one or more assets. The detected anomalies are further classified as potential anomalies and non potential anomalies. The proposed method provides accurate results with 840 reduced processing time. [To be published with FIG. 3] /__1300 Estimating, an initial position of an unmanned aerial vehicle 302 (UAV) inspecting one or more assets in one or more infrastructures Determining, using a plurality of sensors integrated with the UAV, an information related to orientation and direction of 304 the UAV in presence of magnetic interference Acquiring, by navigating the UAV over the one or more assets in the presence of magnetic interference through a dynamically 306 corrected flight path, data pertaining to one or more parts of the one or more assets, wherein at least a subset of the data acquired comprises a plurality of images captured from multiple views Identifying, using domain knowledge driven machine learning technique(s), a region of interest (ROI) in the one or more parts -308 of the one or more assets to obtain a plurality of segmented ROI images Extracting, a plurality of features from each of the plurality of 310 segmented ROI images to detect anomalies in the one or more? assets Classifying, the detected anomalies as one of (i) a potential 312 anomaly or (ii) a non-potential anomaly to predict failure ofho the one or more assets r500 K502 Images are captured and provided as input Detecting railway track lines 5 Estimating position of railway track line on an image 506 Calculating deviation of the railway track line with 508 respect to center of the image in pixel coordinates Converting the deviation in pixel coordinates to real 510 world coordinates (meters) i512 No Deviation greater than a tolerance level olerable leve Yes |Providing Roll correction to the UAV to correct the 514
