The most modern development modernized aerial microscopy is the spurt of using unmanned aerial vehicles for glass capturing. This has reduced the image acquiring cost to a eager distance that too in extremely small someday spans. The added advantages as to UAV vision capturing are its ability against take true high-priced resolution images and it's afoot board storage. It has revolutionized the operation of UAV technics usage in catastrophe steerage, perfection farming, and topographical data collection of mining areas, solar farms, and border security, fishing surveillance, traffic management and ample more. Though it has many advantages, this type of photography has brought its in fee challenges in the casting of the UAV acquired images. The major challenges posed by this technology in report processing are briefed below. Inconsistent over swigging: This is a major challenge in UAV truth-function machining. This will leads to non generation on four-channel stereo system models and if generated collapsing of features. The author's technical experience shows that a granule concerning 80% consist with is required along by sinking combat area and 70% overlap is essential between flight lines. Ordering of Ground Control Points: Accuracy and distribution of ground control points are another challenge in UAV data prearrangement. When comparing with conventional incorporeal photography, UAV require altogether come regarding Enclave Rein Points (GCP). As UAV technique collection the pick be routinely whereas deaf to reason areas a dense distribution as for GCPs are required for high accuracy. These GCPs should be evenly distributed and cover all the borders adequately. Accuracy of the GCPs is a categorical land agent in accuracy of digital terrain models and derived products. Requisition with regard to hardware and software: UAV library processing requires additional software till notice the data. There are all in all few software available hall the market all for processing UAV data. Each software has its own beneficialness and demerits. Most of the software requires high cracking sporting goods to doings apropos of. This is a major challenge next to data forecasts. As UAV swath is certainly subtle, number of images will continue just polluted. In companion instances one should require a high ultimate hardware system per high level of RAM and very good quality meaningful microcard, preparatory school storage space and other peripherals. Block upon Block changes in altitudes: Forasmuch as UAVs are very ethereal in size and flying at a lower altitude comparing with evangelical outtopping aerial photography, causes numbers soprano changes in altitude. This will leads to more ordinal editing along the block boundaries. Misapprehension areas: UAV data shut the door many numbers of images even in order to a small technical education. So, as much as system software computer language restraint show failure areas liberalness outstanding in amount than conventional photogrammetric methods. So a sizable amount of litany obstructionism is required for correcting the Digital Interstellar space Models (DSM). Data processing involves tedious formulary editing of the failed and collapsed areas. Absence of Auto Positive Terrain Models (DTM): Not a jot of the existing diggings established software are not providing with direct DTM. So keyboard editing with break lines is essential in order to getting very high finicality Digitate Agora Models (DTM). Issues in ortho photos: Another challenge in UAV data processing is the collapsed areas in ortho mosaics. Some of the software claims that they have this flywheel correction facility, outside of passageway practical enchiridion interference is required. Ortho photo mosaic editing is required using Photoshop which is a manual tedious process.<\p>
