Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Example one
In order to solve the technical problems in the prior art, the embodiment of the invention provides a method for detecting a cleaning area of a sweeping robot.
Fig. 1 is a flowchart of an embodiment of a method for detecting a cleaning area of a cleaning robot according to the present invention, and as shown in fig. 1, the method for detecting a cleaning area of a cleaning robot according to the present embodiment may specifically include the following steps:
100. if an edgewise command is monitored, controlling the sweeping robot to carry out edgewise sweeping, and recording an edgewise sweeping track;
in general, an outline formed at an edge of a certain space is a maximum coverage area of the space, and therefore, in this embodiment, in order to improve the coverage rate of the sweeping robot, when the sweeping is required, an edge instruction may be generated, so that if the edge instruction is monitored, the sweeping robot may be controlled to find an edge, so that the sweeping may be performed along the edge, and in the sweeping process, an edge sweeping track is recorded. For example, the edgewise sweeping trajectory may be formed by a plurality of trajectory points.
In practical application, if an edgewise instruction is monitored, it needs to be determined whether the edgewise instruction is sent for the first time or not. If the edgewise command is sent for the first time, the sweeping robot starts to move, resets the odometer coordinate system from when the robot moves to the edge position of the current space, starts Simultaneous positioning and Mapping (SLAM), then performs edgewise sweeping, and records the sweeping track points along the edge to form an edgewise sweeping track. If the edge command is not sent for the first time, the edge can be directly cleaned, and the cleaning track points of the edge are recorded to form an edge cleaning track.
The edge finding principle of the embodiment is as follows:
normally, the structured light is located right in front of the sweeping robot, and the structured light has a blind area of about 20cm, so that an object right in front can be detected. Fig. 2 is a schematic diagram of the sweeping robot for finding edges. As shown in fig. 2, if the direction 1 is directly ahead and the inclination angles are 50 degrees (direction 2), 60 degrees (direction 3), and 70 degrees (direction 4) to the right, the detection distance is gradually increased. The problem of the blind zone of the structured light detecting the object directly in front can be avoided by the measurement of the directions 2, 3, 4.
For example, if the distance in the direction 1 directly ahead is 20cm, the distance in the direction 2 is 20cm tan (50) ≈ 23.8cm, the distance in the direction 3 is 20cm tan (60) ≈ 34.6cm, and the distance in the direction 4 is 20cm tan (70) ≈ 54.9 cm.
The sensor real-time supervision is right ahead data, carries out filtering process to the data of sensor, and the distance that detects apart from the barrier constantly reduces, when being less than 20cm, no longer detects the distance of direction 1 this moment, detects the data of direction 2, when the data of direction 2 is less than blind area 20cm, detects the distance of direction 3, and so on. And when the data in the maximum angle direction is less than a certain threshold value, the mark is close to the object and needs to be rotated.
101. If a closed track is formed along the edge cleaning track, determining the track direction of the closed track;
in this embodiment, while the edgewise cleaning trajectory is recorded, it is determined whether the edgewise cleaning trajectory forms a closed trajectory. Specifically, if the edgewise cleaning track is a misaligned track, determining the distance between the starting point of the edgewise cleaning track and the current point of the edgewise cleaning track; and if the distance is smaller than or equal to the preset distance threshold value, determining that the edgewise sweeping track forms a closed track. In this embodiment, the distance between the entrance and the exit is preferably used as the preset distance threshold, so that it is not necessary to determine that the starting point of the edgewise cleaning track and the current point of the edgewise cleaning track are completely overlapped, and it can be determined that the edgewise cleaning track forms a closed track, thereby effectively reducing the error of the determination result.
102. Judging whether the track direction of the closed track is the same as the specified direction, if so, executing a step 103, otherwise, executing a step 104;
in practical application, although the sweeping robot forms the closed track along the edge sweeping track, since the sweeping robot may not directly walk from the edge of the space, in the process of finding the edge, the robot may find the edge of the obstacle first and walk along the edge of the obstacle, and the sweeping robot can also form the closed track along the edge sweeping track, but an internal area corresponding to the closed track is not an area to be swept, and therefore, in this embodiment, it is further necessary to determine whether the internal area corresponding to the closed track is a sweeping area.
Specifically, due to the sensor mounting position of the sweeping robot, the direction of the sweeping robot when walking around obstacles is often opposite to the direction when walking along edges, so in this embodiment, the track direction of the closed track may also be determined, and the track direction of the closed track is compared with the specified direction to determine whether the track direction of the closed track is the same as the specified direction, if the track direction of the closed track is the same as the specified direction, step 103 is executed, and if the track direction of the closed track is different from the specified direction, step 104 is executed.
103. Judging that the inner area corresponding to the edge cleaning track is a cleaning area;
if the track direction of the closed track is the same as the designated direction, the inner area corresponding to the edgewise cleaning track is judged to be the cleaning area, namely, no obstacle detouring action exists.
104. And judging that the inner area corresponding to the edgewise cleaning track is not a cleaning area.
If the track direction of the closed track is different from the specified direction, judging that the inner area corresponding to the edge cleaning track is not a cleaning area, namely, obstacle-avoiding behavior exists, removing the obstacle-avoiding track, and then finding the edge again. In the present embodiment, the designated direction is preferably a counterclockwise direction.
According to the detection method for the sweeping area of the sweeping robot, if the edgewise instruction is monitored, the sweeping robot is controlled to carry out edgewise sweeping, and an edgewise sweeping track is recorded; if a closed track is formed along the edge cleaning track, determining the track direction of the closed track; if the track direction is the same as the designated direction, judging that the inner area corresponding to the edgewise cleaning track is a cleaning area; if the track direction is different from the specified direction, the inner area corresponding to the edgewise cleaning track is judged not to be the cleaning area, so that the detection of the maximum coverage area of the current space is realized, the area which is not cleaned is effectively reduced, the repeated cleaning phenomenon is avoided, and the cleaning efficiency is improved.
In one implementation, two adjacent rooms are typically communicated through a doorway, such as room a and room B. If the sweeping robot determines the cleaning area in the room a, the sweeping robot may enter the room B due to a doorway, and thus the cleaning area in the room B is first determined, and the route in the room a needs to be temporarily stored until the cleaning area in the room a is determined after the cleaning robot enters the room a again from the room B, which often results in low cleaning efficiency. Therefore, in order to solve the above technical problems, the present invention further provides the following technical solutions.
Specifically, after the cleaning area is determined, the sweeping robot can be controlled to continue sweeping along the edge, and the position relationship between the current point of the sweeping track along the edge and a preset range outside the cleaning area is determined; and determining the type of the cleaning area according to the position relation. In this embodiment, if the current point of the edgewise cleaning track is located outside the preset range outside the cleaning area, it indicates that the sweeping robot has traveled to the doorway, and it may be determined that the type of the cleaning area is an opening area. In order to prevent that the determined cleaning area cannot be cleaned in time after the cleaning area is determined, in this embodiment, when it is determined that the current point of the edgewise cleaning track is located outside the preset range outside the cleaning area, the sweeping robot is controlled to stop the edgewise cleaning so as to return to the determined cleaning area and then clean the determined cleaning area.
In this embodiment, if the current point of the edgewise cleaning trajectory is located inside the preset range outside the cleaning area, it is determined that the current space is a closed space, that is, the entrance and exit are in a closed state, and it can be determined that the type of the cleaning area is a fully closed area. At the moment, the sweeping robot can be controlled to stop sweeping along the edge after the sweeping robot walks to the edge starting position, so that the determined sweeping area can be swept again.
It should be noted that the method of the embodiment of the present invention may be executed by a single device, such as the sweeping robot itself, a terminal or a server. The method of the embodiment can also be applied to a distributed scene and completed by the mutual cooperation of a plurality of devices. In the case of such a distributed scenario, one device of the multiple devices may only perform one or more steps of the method according to the embodiment of the present invention, and the multiple devices interact with each other to complete the method.
