Panoramic computer system for realizing controllable advancing display of streetscape map

Abstract

The invention discloses a panoramic computer system for realizing controllable advancing display of a streetscape map, which comprises the following steps of: in a streetscape map environment with a panoramic image set based on an electronic map, controlling an advancing starting point and an advancing direction, according to a set advancing distance and a set time interval and along the advancing direction; a plurality of panoramic images are automatically and sequentially extracted and displayed one by one, so that the panoramic images are automatically extracted and displayed in batches along the route in the electronic map in sequence and in a delayed manner, and the problem that repeated man-machine interaction is needed to position and display the panoramic images when a plurality of panoramic images are manually extracted and displayed on the electronic map along the route in the prior art is solved; the working efficiency of displaying the plurality of panoramic images along the route is improved, and meanwhile, compared with a full-automatic playing technical scheme of extracting and displaying the plurality of panoramic images one by one along the route, the controllability of route and direction change is enhanced.

Description

technical field [0001] The invention relates to the technical field of Internet geographic information, in particular to a computer system for realizing controllable marching display of a street view map. Background technique [0002] Based on the electronic map, the street view map integrated with massive panoramic images has become a new and open geospatial data resource. The panorama image acquisition method is mainly that the panorama image acquisition vehicle travels along the street at a constant speed, and takes a panorama image and its longitude and latitude coordinates at a certain distance. The Internet geographic information service platform provider provides an open platform for the development and utilization of electronic maps and panoramic images, such as Provide Android, iOS, and Web development open platforms for free to realize the call and display of electronic maps and panoramic images, and build feature-rich and interactive electronic map applications. ...

Problems solved by technology

The panoramic image in the street view map is automatically collected along the route, but relying on the existing Internet street view map, such as "Earth Online Street View Map" or well-known street view map service providers at home and abroad, it is necessary to rely entirely on manual operations on the electronic map , through human-computer interaction, move the mouse continuously on a certain road section of the electronic map to repeatedly query and obtain multiple panoramic images, just like "single shot", which is vividly said to be "one shot to change a place", and the positioning position of manual operation is random Strong and difficult to repeat, the problem is prominent, or the mouse is constantly moved in the panoramic image window and the direction arrow is repeatedly operated to obtain the front panoramic image, and the work efficiency of manual operation for a long time is greatly reduced; in view of the above problems, "a way to realize street view display Method and device" (Application No.: 201410457789.3, patent authorization announcement No. CN 104199944 B) has carried out a beneficial exploration, which adopts pre-generated part of the panorama images within the field of view angle range of each road section along the direction of road travel to splicing into dynamic images, according to the received The coordinates of the starting point and end point of the starting point and the end point are generated to automatically play the dynamic image. This solves the problem of manual operation in the prior art and obtains the quick advantage of the automatic playback of the dynamic image. The disadvantage of playing is that it is like a "Katyusha rocket launcher", once it is started, manual intervention and adjustment can no longer be implemented; in addition, "a computer system for displaying panoramic images along the electronic map" (application number: 2019104154393, patent authorization announcement number: CN 110110248 B ) has also carried out useful explorations. By sequentially receiving the latitude and longitude coordinates of a series of points, a polyline with a direction of travel is formed to represent the route set on the electronic map. Within the polyline, multiple points are automatically sequentially extracted and displayed along the direction of travel at certain intervals. Panoramic images, realize the one-by-one extraction and directional display of panoramic images of the electronic map, solve the problem of automatically extracting and directional displaying multiple panoramic images on a certain delineated road section of the electronic map, change the manual operation of panoramic image extraction and display of street view maps one by one, reduce The number of human-computer interaction actions has been increased, and the work efficiency of directional display of multiple panoramic images within a delineated line has been improved, but the disadvantage is also like a "Katyusha rocket launcher", once it is started, manual intervention and adjustment cannot be implemented; A technical problem that technicians are eager to solve is how to manually simulate the "single shot" browsing panoramic image technical solution on the above-mentioned existing street view map and how to fully simulate the automatic cruise driving along the specific line as mentioned in the above two invention patents. Katyusha Rocket Launcher” to seek a compromise semi-automatic and controllable browsing panoramic image technical solution, that is, in the street view map environment based on the panoramic image collection on the electronic map, by controlling a geographic travel The initial point and direction of travel, according to the set travel distance and time interval, along the direction of travel, simulates the basic driving actions, controls start, stop, steering and other actions, automatically travels, sequentially extracts and displays multiple A panoramic image, to realize a semi-automatic simulation of manual driving on a street view map, and to implement a semi-automatic travel query display panoramic image technology solution that can be manually intervened. On the one hand, this technical solution solves the problem that traditional manual extraction and display of multiple panoramic images along the route on the electronic map requires repeated human-computer interaction to locate and display the panoramic images, and improves the work efficiency of displaying multiple panoramic images along the route. On the other hand, , there is no need to input a specific and uncontrollable section of the set route during the travel process, the input volume is relatively reduced, and at the same time, the controllability of the geolocation process of the query is increased, that is, "manual driving" is realized. The control of this technical solution The simplicity of the part is closer to the above-mentioned purely manual technical scheme of the existing street view map. The animation effect of the output of this technical scheme, the continuous walking stage is similar to "a computer system that realizes the display of panoramic images along the electronic map" (application number: 2019104154393) Cruise driving plays panoramic images
