27. Support map navigation UAV returning 28, three-dimensional data acquisition to provide fast accident recovery analysis.
(4)The system can draw the scale map of traffic accident scene quickly and accurately, draw the scene map by computer, automatically and quickly draw the sketch of road traffic accident scene, generate the scale map according to the requirement, and automatically generate the record of accident scene investigation.；(5)There are three independent drawing layers in the system, which can distinguish roads, icons and traces. The layers can be stored in layers by layers, so that no interference can be caused in drawing, and the wrong operation can be avoided effectively. Supporting triangular and right-angled positioning methods used separately or in combination, automatic and manual annotation can be used.；(6)The drawing process conforms to the traditional drawing process habit of police officers. It does not need to fill in forms, and WYSIWYG is easy to find errors in real time. The operation adopts full left-click dragging operation mode, completes the same operation with the least number of keystrokes, shields right-click operation, and facilitates operation on tablet computer and field use.；(7)It is easy to draw various forms of roads (such as straight roads, forks, etc.) with a handwritten pen.SBends, intersections, T-junctions, various complex intersections, road profiles, unequal broad roads, irregular roads, etc.；(8)The parameters of the whole road can be set, and the parameters of each road can also be set (e.g. the width of lanes, the number of lanes, the width of individual lanes, etc.). The shape and style of various markings and green belts can be adjusted arbitrarily.；(9)Special roads can be generated (e.g. expressways, urban and rural roads, County roads, etc.).SShape road, etc.SV-bend can be dragged freely by multiple control points, and various data can be marked automatically.；(10)It has the function of road memory, which can store the roads involved in the field maps and be easy to call directly in the future. It also has the function of road pre-storage, which can input the template of accident-prone sections and complex sections in advance, so as to make the field mapping more convenient and fast, or use it in combination with electronic map data.less thanData provided by usersgreater than；(11)Open symbol library, labeled symbols are drawn according to national standards in advance, users can add non-standard symbols manually; all other symbol libraries are managed by open database, which is easy to add, delete, modify or personalize according to regional characteristics.；(12)The labeled symbols should be added according to the national standard, and special symbols can be added manually. Open management of road map database and vehicle feature symbol is adopted in order to add, delete, modify or set individually according to regional characteristics.；(13)Automatically adjust the size and position of the input data to determine the required positioning data,And input the measured data into the corresponding items of the computer.,Click on the automatic adjustment button to adjust the position of each icon element in the actual position relationship transfer diagram. The automatic marking line and location distance can be automatically generated to avoid missing important parameters.；(14)The system provides error warning function, which can prompt for data missing, data redundancy and data logic errors, so as to avoid errors in exploration or data filling.
