Problems solved by technology

[0003] However, the inventors have found that at least the following problems exist in the prior art: the robots with autonomous positioning and navigation functions are not only walking indoors and other places with flat roads, but also need to walk outdoors and other environments with complex ground conditions, such as paving with cobblestones. the road
When walking on undulating roads, the robot will continue to bump, which will cause the image acquisition device (such as a camera) used to collect images of the surrounding environment to be in the exposure state for a long time, and it will not be possible to capture a clear image
Since the captured images of the surrounding environment are not clear and cannot be matched with the pre-built map to locate the current location of the robot, the robot cannot plan the navigation route in a timely and accurate manner and complete the work, which also seriously affects the user's use to experience

Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present application clearer, some embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0022] The first embodiment of the present application relates to a positioning method, which is mainly applied to robots with autonomous positioning and navigation functions, and its specific process is as follows figure 1 shown.

[0023] In step 101, it is determined that the positioning through the surrounding environment image fails during the process of driving to a preset distance.

[0024] Specifically, when the robot travels to the preset distance, the operation of positioning through the surrounding environment image can be realized in the fol...

Abstract

The application relates to the technical field of visual navigation, and discloses a positioning method, device, robot and computer-readable storage medium. In this application, the positioning method is applied to a robot with autonomous positioning and navigation functions, which includes: determining that the positioning through the surrounding environment image fails during the process of driving to a preset distance; controlling the robot to slow down, and during the slow down process Positioning is carried out through the surrounding environment image until the positioning is successful. The positioning method can reasonably adjust the running speed of the robot according to the environment where the robot is located during the driving process of the robot, and accurately locate the position of the robot.

Description

technical field [0001] The present application relates to the technical field of visual navigation, in particular to a positioning method, device, robot and computer-readable storage medium. Background technique [0002] With the rapid development of science and technology, such as sensor technology and artificial intelligence algorithms, the robot's autonomous positioning and navigation technology based on visual real-time localization and map construction (VSLAM) has achieved certain results, which further enriches the functions of the robot and makes the robot's The scope of application continues to expand. For example, automatic delivery robots used in the logistics industry are gradually replacing people to complete part or all of the work, allowing more and more people to get more personal leisure time in order to enjoy life. [0003] However, the inventors have found that at least the following problems exist in the prior art: the robots with autonomous positioning an...
