Problems solved by technology

[0003] Specifically, the trajectory map can only simply record the overall trajectory of the path, but cannot describe the local information of the path, while the recording method using video can describe the local information of the path, but it cannot reflect the overall trajectory information of the path, and requires A large amount of storage capacity makes it difficult to find path information, which needs to be viewed through the time axis

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] see figure 1 , 2. The existing track recording products on the market can only simply record the overall track of the route, but cannot describe the local information of the route. See image 3 , the way the video records the path does not reflect the overall trajectory.

[0021] The road recording method based on the image conversion of the present invention puts the road surface image information on the map through the image conversion, so that the detailed information of the overall track and the road surface is obtained. The path recording method based on image transformation of the present invention comprises the following steps:

[0022] 1) Take pictures with a mobile phone or a digital camera, and collect image data fused with GPS data;

[0023] 2) Separate the GPS data from the image data to obtain a two-dimensional array corresponding to on...

Abstract

The invention discloses a path recording method based on image transformation. The method includes the following steps that (1) path image data containing GPS data are collected; (2) the GPS data andthe image data are separated, so that image data in which each GPS datum corresponds to one path image are obtained; (3) the GPS data are converted into map image coordinates, and each map image coordinate corresponds to an image array of each path image; (4) the image data of the path images are transformed relative to images corresponding to the image coordinates, and background images are added; and (5) the transformed images with the added background images are printed, and path recording images are obtained. The method can not only record a whole track of a path, but also can describe local information of the path, and has the characteristics of low cost, high speed and high reliability.

Description

technical field [0001] The invention relates to a path recording method, in particular to a path recording method based on image conversion. Background technique [0002] Recording the path can facilitate the selection of a more suitable path in subsequent path planning, and summarize the advantages and disadvantages of the recorded path. Existing path recording methods include trajectory graphs and video recordings, but there are some shortcomings in these methods. [0003] Specifically, the trajectory map can only simply record the overall trajectory of the path, but cannot describe the local information of the path, while the recording method using video can describe the local information of the path, but it cannot reflect the overall trajectory information of the path, and requires A large amount of storage capacity makes it difficult to find path information, which needs to be viewed through the time axis. Contents of the invention [0004] The object of the present...
