Embodiment Construction

[0054] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] figure 1 It shows the structural principle diagram of the mobile robot dead reckoning correction system of the present invention, and the system includes a mobile robot dead reckoning unit and a dead reckoning correction unit.

[0056] The dead reckoning unit of the mobile robot includes an odometer, an inertial navigation sensor and a dead reckoning module installed on the robot; the odometer is used to collect the travel distance of the mobile robot, and the inertial navigation sensor outputs the inertial navigation of the robot in real time In the direction, the dead reckoning module is used to calculate the driving trajectory and positioning point of the mobile robot. The odometer is composed of left and right wheel speed sensors, which are respectively installed on the left and right hubs of the rear wheels of the robot, and the w...

Abstract

The invention provides a mobile robot dead reckoning correction system and method based on straight-going intersection detection, the method is simple and the accuracy is high. The system includes a mobile robot dead reckoning unit and a dead reckoning correction unit; the mobile robot dead reckoning unit includes an odometer, an inertial navigation sensor and a dead reckoning module installed on the robot; the dead reckoning correction unit It includes a camera installed on the robot, an intersection detection module and a correction module. Firstly, the mobile robot is dead reckoned by odometer and inertial navigation data to obtain the initial positioning position, and then by obtaining the data obtained based on the detection of the zebra crossing at the intersection, combined with the electronic map data, the dead reckoning position is corrected to obtain a relatively accurate movement Robot location.

Description

technical field [0001] The invention relates to the technical field of positioning of a mobile robot, in particular to a dead reckoning correction system and method for a mobile robot based on straight road intersection detection. Background technique [0002] With the continuous development of information technology, the application of robots has become more and more extensive, and has penetrated into almost all fields, among which mobile robots are an important branch of robotics. As early as the 1960s, research on mobile robots had already begun. Mobile robots include indoor mobile robots and outdoor mobile robots in terms of working environment. Robots based on mobile driving in outdoor environments have been applied to intelligent transportation systems and military combat systems. In intelligent transportation systems, mobile robots can significantly improve the driving performance of vehicles. Security, in the military combat system, mobile robots are playing an incr...
