Description

Technical Field

[0001] The utility model relates to the technical field of land survey, in particular to a tool for providing evidence in the field of land survey. Background Art

[0002] During the process of land survey or land change survey, in accordance with the requirements of the superior technical plan, the county level should use mobile phones or tablet devices with satellite positioning and direction sensors while conducting field surveys, and use the "Internet +" evidence software to take evidence photos or videos of the map blocks that need to be proved, including the actual coordinates of the map blocks, shooting azimuth, and shooting time.

[0003] Evidence photography requirements: Evidence photos should be taken in the correct direction on the spot, and should be sufficient to illustrate the land use situation in the area where the surveyed land type is inconsistent with the image characteristics. Evidence photos should be able to reflect the overall picture and utilization characteristics of the map, and should be taken at three or more different standing points. Only one best photo can be uploaded from the same standing point and the same direction, and each map must not have less than 3 evidence photos. For the map investigated as construction land, if the external evidence photos are not sufficient to confirm that it is construction land, internal photos should also be taken; for the map investigated as facility agricultural land, photos of the interior and exterior of the building or photos of buildings (structures) that can reflect the purpose should be taken (threshing grounds that can be accurately identified based on image characteristics do not need to be provided as evidence). During the photo shooting process, attention should also be paid to the beauty and rationality of the photo shooting. The photos taken should have the sky above and the ground below. Pay attention to avoid shooting at the ground, the sky, and the wall. Avoid standing in front of obvious obstructions such as electric poles, street light poles, trees, fences, and enclosures to avoid obvious obstructions in the photos.

[0004] In the actual field evidence presentation process, due to the limitations of the on-site conditions, in order to take evidence photos that meet the requirements as much as possible, it is often necessary to use ladders and other tools to stand at a commanding height to take photos. However, when presenting evidence in the field, it is impossible to equip each field evidence presenter with a ladder. Moreover, standing on a ladder to present evidence in the field increases the safety risk of field personnel falling, which in turn affects the efficiency of field evidence presentation. In addition, if the mobile phone is directly mounted on a selfie stick and held high for field evidence presentation, the shooting direction and quality of the photos cannot be checked during shooting, and the quality of the photos cannot be guaranteed.

[0005] Therefore, it was decided to design a tool for field evidence collection in land surveys to facilitate the taking of evidence photos that meet the requirements. Utility Model Content
