Problems solved by technology

[0005] As a distance measurement method, radar or laser is mainly used. At this time, if the number of vehicles increases, there is a possibility of mutual interference or interfering with each other.
In addition, when installing sensors on roads, there is a problem that construction costs increase
Therefore, as a method of measuring the distance from each vehicle, there is a method of coloring the road like a checkerboard, but this method requires a lot of expenses.
In addition, when drawing lines separately from the traffic lanes on the road, a large amount of expenses will also be incurred.

Abstract

The invention discloses a distance and position measuring method and apparatus using image tracking for automatic driving. The distance and position measurement method using image tracking for automatic driving according to one side of the present invention is executed by a computer device, and comprises the steps of recognizing a square or rectangular mesh matching part marked on a road captured by a camera; a step of generating a virtual grid applicable to a road by using the grid matching unit; and aligning the four points of corners of a rectangle in the virtual grid with four points of corners of the grid matching part by geometric deformation to generate a three-dimensional plane coordinate, and calculating the distance to the object by using the plane coordinate.

Description

technical field [0001] The invention relates to a distance and position determination method and device using image tracking for automatic driving. Background technique [0002] For automatic driving of vehicles, accurate position measurement of the vehicle and distance measurement technology with other objects are particularly important. That is, it has become an important hot spot to identify the exact coordinates of the current position of the vehicle and measure the distance based on its position for safe automatic driving. distance to obstacles, etc. [0003] A GPS receiver is used to determine the position, but GPS also produces a certain degree of error, and this error may cause collisions with fast-moving vehicles. Therefore, a more accurate position measurement method is currently required. . [0004] That is, the GPS currently used in a vehicle measures its own latitude and longitude through an American military artificial satellite. However, due to the militar...
