Embodiment

[0044] This embodiment discloses a method for spatial positioning of automobile fuel filling ports based on geometric modeling, the method is as follows:

[0045] Add external markers on the plane of the car's fuel filler;

[0046] The image of the fuel filling port and markers is collected by the camera, and the position of the fuel filling port and the marker is identified and positioned by the monocular vision positioning method;

[0047] Compute the relative spatial coordinates between the camera and the marker and fuel filler;

[0048] According to the spatial geometric relationship between the camera and the marker, the spatial attitude of the fuel filling port of the vehicle is solved, and the fuel filling port is positioned.

[0049] There are multiple external markers, which are arranged on the left and right sides of the fuel filling port or around the fuel filling port. The external markers are cross markers or eye-catching signs. The marker can help to quickly id...

Abstract

The invention discloses an automobile fuel filling port space positioning method based on geometric modeling. The method comprises the following steps: adding an external marker on an automobile fuel filling port plane; images of the fuel oil filling port and the marker are collected through a camera, and the positions of the fuel oil filling port and the marker of the automobile are recognized and positioned through a monocular vision positioning method; calculating relative space coordinates between the camera and the marker as well as between the camera and the fuel filling port; and according to the spatial geometrical relationship between the camera and the marker, the spatial attitude of the automobile fuel filling port is solved, and the fuel filling port is positioned. The problem that in the prior art, an automobile fuel oil filling port is difficult to position accurately is solved.

Description

technical field [0001] The invention relates to the technical field of spatial modeling and positioning, in particular to a spatial positioning method for an automobile fuel filling port based on geometric modeling. Background technique [0002] Existing object spatial positioning methods mainly include PNP-based pose estimation algorithms, deep learning-based object pose solving methods, and feature-matching-based spatial positioning methods. First of all, there are few spatial positioning methods for automobile fuel filler ports based on geometric modeling, and the existing vision-based positioning technology solution methods require a large number of feature processing processes. If the feature engineering construction is not perfect, it will have irreversible consequences on the results. Contents of the invention [0003] For this reason, the present invention provides a spatial positioning method for the fuel filling port of an automobile based on geometric modeling ...
