Embodiment 1

[0027] A automatic charging method based on a reverse image, characterized in that the steps of:

[0028] Step 1, target recognition:

[0029] Such as figure 1 As shown, set color positioning point A on the charging pile. When the vehicle is parking, the reversing image takes a photo containing the positioning point A. Target identification uses color-based recognition algorithm Meanshift algorithm (prior art), the specific steps are as follows:

[0030] (1) Select a search box W in the color distribution map;

[0031] (2) Calculate the zero-order matrix M 00 = Σσi (x, y); where

[0032] (3) Calculate the first order matrix M 01 = Σσxi (x, y) and m 10 = Σσyi (x, y);

[0033] (4) Calculate the size of W;

[0034] (5) Ask the centroid coordinates of the search box, namely the centroid coordinates of color positioning point A.

[0035] Step 2, the target positioning:

[0036] The three-dimensional coordinate M1 of the positioning point A is obtained by using the single-graphic positi...

Embodiment 2

[0044] An automatic charging system based on reversing images, including:

[0045] The image acquisition unit is acquired using the camera of the reversing image to collect the image of the color positioning point set on the charging pile; the target identification module, calculates the catholic coordinates of the color positioning point based on color-based recognition algorithm;

[0046] Target positioning module, uses the three-dimensional coordinates of color positioning points using the single-graphic positioning principle of the reversing image;

[0047] The coordinate conversion module converts the camera coordinate system into a world coordinate system with a color positioning point as the coordinate origin, and obtains the three-dimensional coordinate of the camera core relative to the color positioning point;

[0048] The coordinate superposition module is superimposed on the three-dimensional coordinates of the camera core relative to the color positioning point, and t...

Description

Technical field [0001] The present invention relates to an automatic charging system and method belonging to the field of new energy vehicle technology. Background technique [0002] Automobile charging is the hot spot in the new energy automotive industry research, and no one is charging is the direction of future development. Most of the existing charging piles are manually charged, and the charging efficiency is reduced, and the human is wasted. Some charging piles use unmanned charging methods, but traditional binocular positioning methods need to be used in two cameras, although the precision is high, but the cost of two cameras is expensive. With the development of the new energy vehicle industry, use the machine instead of manual, fully automatic, high-precision positioning and low cost charging system to become the industry's pursuit. Inventive content [0003] It is an object of the present invention to provide an automatic charging method, achieving unmanned charging, ...
