Problems solved by technology

However, since the robot does not know the location of the landmarks, the robot can only turn on the lighting source for a long time to ensure that the camera can capture the landmarks at any time, which leads to the rapid consumption of the robot's own power, which not only reduces the use time of the robot, but also wastes energy. Increased robot usage cost
Another solution is to set a lighting source on the road sign, but the lighting source also needs to be turned on all the time, which also wastes energy and cost

Embodiment 1

[0037] See attached figure 1 , which shows the schematic structure of the navigation landmark of the present invention. The navigation road sign of the present invention includes a housing 4, a coordinate function induction light 2, an encoding function induction light 3 and a power supply (not shown in the figure).

[0038] The front of the housing is provided with induction light interfaces (N≥3) arranged in an N×N array, and each induction light interface can be equipped with an induction light. The back of the housing is connected and installed on the ceiling, and a power supply is arranged in the housing, and the power supply is connected to each induction lamp interface, and is used to supply power to the installed induction lamps, and can also supply power to other devices in the road signs.

[0039] Such as figure 1 As mentioned above, on the three corners of the array, a coordinate function induction lamp 2 is respectively set, but on the other corner 1B, no inducti...

Embodiment 2

[0048] On the basis of the first embodiment above, the robot involved in this embodiment further includes an adjustment device, which can adjust the luminous intensity of the light source device under the control of the main control system, so as to emit infrared light with different brightness and ultraviolet light. Correspondingly, the infrared sensor lamp on the road sign can emit light of different brightness based on the intensity of the received infrared light. The stronger the intensity of the received infrared light, the brighter the light emitted by the infrared sensor lamp; similarly, the road sign The UV sensor lamp on the camera can also emit light with different brightness based on the intensity of the received UV light. The stronger the intensity of the received UV light, the brighter the light emitted by the UV sensor lamp. Under the same intensity of infrared light and ultraviolet light, the brightness of the infrared induction lamp and the ultraviolet inductio...

Embodiment 3

[0053] In the actual application of the robot, the shooting of road signs may also be affected by the shooting angle. Since the road signs are set on the ceiling, the most suitable shooting position for the robot is directly below the road signs, but in actual operation, it may not be possible to do so. to this point. Therefore, on the basis of the above two embodiments, the road sign of this embodiment also includes a base plate, the back of the housing of the road sign is connected and installed on the lower surface of the base plate, the base plate is suspended from the ceiling, and has a turning mechanism and a rotating mechanism . The bottom plate is initially in a horizontal state, the turning mechanism can make the bottom plate tilt to a specified angle, and the rotation mechanism can make the bottom plate rotate around a vertical axis passing through its center. The base plate also includes a controller and a wireless communication device, the controller can control t...

Abstract

The invention relates to a robot navigation road sign and a recognizing method. The robot navigation road comprises an infrared induction lamp and an ultraviolet induction lamp; the induction lamps are turned on after receiving infrared light and ultraviolet light; a lighting device capable of emitting infrared light and ultraviolet light is arranged on a robot; and when the road sign cannot be clearly recognized under the insufficient light condition, the robot emits infrared light and ultraviolet light to light up the road sign, so that recognizing the road sign by the robot is facilitated.

Description

【Technical field】 [0001] The invention belongs to the field of robot visual navigation, and in particular relates to a navigation landmark used in robot visual navigation and a recognition method. 【Background technique】 [0002] Usually, in order to control the movement of an indoor robot indoors, the robot needs to recognize its own position. In the prior art, artificial landmarks are mainly used. For example, an artificial landmark with a certain pattern is installed on the ceiling, and a camera is installed on the top of the robot to photograph the ceiling. When the artificial landmark is photographed, the image of the photographed landmark is processed to identify the landmark, and then determine the location of the robot itself. Spatial location. [0003] In the above-mentioned prior art, the clarity of the artificial road sign image captured by the robot is very important, but the clarity of the camera is largely affected by the illumination light. If the road sign is...
