Embodiment

[0046] Such as figure 1 As shown, a color-coded identification-based robot navigation method includes the following steps:

[0047] In step S101, a video signal is acquired through a camera, and image data is collected. The robot obtains the video signal through the camera. The digital camera is a digital video input device. The color bit is generally 24bit, and the average video capture speed is 30 frames per second.

[0048] Step S102, extracting the navigation marking line and determining the path direction according to the collected image data. Image processing is performed on the collected image data to identify and extract the navigation line, that is, to separate the navigation line from the background image. Identify the navigation marking lines laid on the ground through the visual method. The advantage of this method is that it has strong versatility. No matter what kind of environment it is in, as long as there is a track line, the robot can move along the line, a...

Abstract

The invention discloses a robot navigation method based on color coding identifiers, which comprises the following steps of: extracting a navigation identification line according to the acquired image data, and determining the path direction; identifying a breakpoint mark in front of the color coding identifier, and preparing to regulate the movement trail for the color coding identifier; and identifying a color coding block around a corner or other positions, and executing turning or other command. The invention further discloses a robot navigation system based on the color coding identifiers. The robot navigation system has a simple principle, strong expandability and good visual perception, and can complete the positioning and navigating tasks of an indoor service robot; the robot navigation system can be combined with other navigation systems, so the stability and practicability of the navigation system are improved; and the problems of weaker applicability to complicated environments, error navigation accumulation, large operand, mutual interfered sensors and the like in the current robot navigation field can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of robot navigation control, in particular to a robot navigation method and system based on color-coded identification. Background technique [0002] The existing robot navigation control mainly uses electromagnetic or ultrasonic sensors for navigation. The measured data is relatively direct, and the data processing capability of the sensor is not high, but non-visual sensors will pollute the detection environment, such as microwave, ultrasonic, etc. Etc., each sensor will also interfere with each other. Using sensors such as gyroscopes and compass for inertial navigation, the displacement relationship between the robot and the initial position can be known by calculating the accumulated detection data. This method can obtain relative displacement information. increased by exercise. Visual navigation has the advantages of wide detection range and rich information. However, it is difficult to overcome the d...
