Embodiment Construction

[0020] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0021] Such as figure 1 As shown, the virtual image-oriented robot navigation method includes:

[0022] Step 1. Acquire a first image and a second image, and calculate a first bidirectional flow field between the first image and the second image.

[0023] Step 2: Using the first bidirectional flow field to generate a first virtual perspective image corresponding to the first image and a second virtual perspective image corresponding to the second image.

[0024] Such as figure 2 As shown in , there is also a flow field correspondence between the virtual perspective image and the first image and the second image. Set the image represented by the virtual viewing angle to appear as figure 2 As shown, it can be considered that there is a ...

Abstract

The invention discloses a robot navigation method oriented to virtual images. The method comprises steps as follows: a first bidirectional flow field between a first image and a second image is calculated; a first virtual view angle image and a second virtual view angle image are generated by adopting the first bidirectional flow field; a second bidirectional flow field between the first virtual view angle image and the second virtual view angle image is calculated, and field depth information of the first virtual view angle image and the second virtual view angle image is calculated; the first virtual view angle image and the second virtual view angle image are subjected to image close-up according to the field depth information, and a virtual image is obtained through fusion of an obtained first virtual close-up image and an obtained second virtual close-up image; a panoramic view image of an ambient environment of a robot is acquired and matched with the virtual image for azimuth positioning; a distance calculation function of the robot is fitted out according to a corresponding relation between an image feature point ratio and a distance, and a motion distance of the robot is output. The robot navigation method has the advantages of smaller storage data, low memory consumption and high calculation speed.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a virtual image-oriented robot navigation method. Background technique [0002] Robot (Robot), as a mechanical device, can automatically perform specified work, and at the same time it is a new type of substitute for human activities. From the first industrial revolution to the present, science and technology have been advancing step by step, and the development of robot technology has become more and more popular. Similarly, human beings have an increasing demand for robots, and various types of robots have emerged as the times require. From the expansion of industrial production, nuclear energy, medicine, biochemistry, household cleaning, deep sea development, medical rehabilitation, Mars exploration, etc., robots appear in every corner of human society. In many applications, robots are gradually liberated from fixed machinery, and the demand for navigation technology is im...
