The invention provides a map navigation method. The method comprises the following steps: a server receives a real time image sent by a mobile terminal and navigation condition information for confirming a navigation path, wherein the navigation condition information includes information of a navigation destination; comparing the real time image with a data image in an image database, and determining the current position and direction of the mobile terminal; calculating a navigation path from the current position to the navigation destination according to the navigation condition information; and obtaining the traveling direction identifier information of the navigation path according to the navigation path, the traveling direction of the navigation path and the current position and direction of the mobile terminal, and sending the traveling direction identifier information to the mobile terminal. The invention also provides a map navigation apparatus and a system thereof. The map navigation method, the apparatus and the system realize map navigation of the real time image shot by a user, and can improve the navigation efficiency.

The invention provides a navigation method in live-action function on a mobile terminal. The method comprises the steps of running an electronic map program on the mobile terminal; determining a target site address according to operations of a user on the electronic map program; acquiring a current geographical location of the mobile terminal; displaying a live-action shooting image on the mobile terminal; drawing a navigation route in a live-action function interface according to the current geographical location and the target site address; detecting a ground image area in the live-action shooting image; mapping the navigation route to a plurality of characteristic points of the ground image area; identifying movement of the characteristic points of the ground image area on the live-action shooting image; and keeping continuity of the navigation route along a connecting line of the characteristic points. Accordingly, the invention provides an electronic map client. The navigation method and the electronic map client can increase navigation efficiency of a live-action function.

The invention relates to a method for calibrating zero offset of a quartz flexible accelerometer component, which is a system grade calibrating method using a velocity error as observed quantity. In the method, the conventional calibration equipment is still used, the six-position calibration scheme has simple operation and high calibration accuracy; and compared with conventional multi-position division calibration test, the calibrating time of the method of the invention is greatly shortened, calibration errors caused by rotary table errors when multiple positions are calibrated are reduced, and the navigation performance of a strapdown inertial navigation system can be improved. The invention provides a practical system grade calibration method for the accelerometer component.

The invention discloses a real-time navigation method based on road conditions. The method comprises: a road condition acquisition unit periodically collects real-time traffic information of each road section, and sends the real-time traffic information to a real-time traffic server, and the real-time traffic server receives the real-time traffic information After information processing, the real-time congestion degree of each road section is obtained; the terminal navigation device obtains the starting position and the end position, and provides driving route 1 after path calculation; the terminal navigation device obtains the congestion degree of each road section from the current position to the end position, based on the congestion degree The lowest strategy provides driving route 2; the terminal navigation device obtains the predicted congestion degree of each road section from the current position to the terminal position after a predetermined time period, and provides driving route 3 based on the lowest predicted congestion degree strategy. Compared with the prior art, the present invention enables users to conveniently and clearly know the real-time road conditions on the way and the predicted road conditions after a period of time, provides three routes for users to choose, has strong real-time performance, and improves navigation efficiency.

The invention discloses a shutter type hydraulic self-control gate. The shutter type hydraulic self-control gate comprises a gate frame, window lattices, small door leaves and small door spindles, wherein, a plurality of window lattices are arranged in the gate frame; the small door spindles are arranged at the top part of the window lattices; the small door leaves are suspended on the small door spindles; a large door spindle is arranged at the top part of the gate frame to form a top spindle shutter type hydraulic self-control gate; and a large door spindle is arranged at the bottom part of the gate frame to form a bottom spindle shutter type hydraulic self-control gate. The top spindle type and fixed type shutter type hydraulic self-control gate can efficiently utilize tidal power resources in riverine and coastal areas and effectively control reservoir deposits of tidal power station, and provides safe energy and water insurance for the development of riverine and coastal areas. The bottom shaft type shutter hydraulic self-control gate can be used as a navigation gate of a ship elevator, reduce the open and close resistance of a flap gate and the error of water level of navigation, shorten navigation time, and comprehensively improve the navigation efficiency of ship elevators. Compared with the traditional gate, the shutter type hydraulic self-control gate has good work state and the passing water current is uniform.

The invention provides a path navigation method and device. The method comprises the steps that query data are obtained, the query data comprise a departure point and a destination point, and two or more navigation paths from the departure point and the destination point are further obtained according to the query data, so that the two or more navigation paths can be output in a navigation map. Not only one navigation path is displayed in the navigation map any more, instead, all the navigation paths can be displayed, therefore, the technical problem that in the prior art, data interaction between an application and a terminal is increased due to the fact that a user switches applications repeatedly so as to display all the navigation paths on the navigation map can be avoided, and thereby processing burden of the terminal is lowered.

The invention discloses a multi-destination path navigation method, comprising the following steps: a) selecting an interest point through a mobile terminal to serve as a destination, sending a path navigation request to a server, and calculating a first navigation path through the server with the destination as end point; b) searching interest points with the same name or category within a preset range on the surrounding of the destination through the server; c) if interest points with the same name or category exist, using all searched interest points as end points, and continuing to calculate the navigation path to obtain a plurality of second navigation paths; d) respectively comparing the plurality of second navigation paths with the first navigation path, and if a second navigation path with better pre-estimated distance or pre-estimated time obviously exists, simultaneously sending the second navigation path and the first navigation path to the mobile terminal for selection. By adopting the multi-destination path navigation method provided by the invention, detour or time waste caused by improper destination selection of a user is avoided, and the navigation efficiency is greatly improved.
