Embodiment Construction

[0033] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] figure 1 Shown is a mobile robot applying the present invention, which includes a self-propelled unit 1, a communication unit, and a working device 2. In order to realize the control of the mobile robot, the present invention is also provided with an image acquisition device 4 above its working area 3 to constitute a control system for the mobile robot. Wherein, the mobile robot may be a lawn mower robot or other robots with a self-propelled function for outdoor environments. The lawn mower robot can also be provided with a map construction unit and a path planning unit, which are used to construct a map of the work area of ​​the lawn mower robot according to the im...

Abstract

The invention discloses an out-of-bound judgment method and system for a mobile robot. According to the invention, the global video image data of the working area is acquired through the image acquisition device arranged above the working area; By selecting and identifying pixel points in the image, especially by clicking or drawing the working area range of the automatic walking device in the image and automatically identifying the mobile robot in the image, automatic judgment on demarcation of the mobile robot is realized. Therefore, effective positioning of the mobile robot and constructionof a working area map can be automatically realized in an open environment, real-time out-of-bound judgment is realized based on the effective positioning and the construction of the working area map, and the operation efficiency and the operation safety of the mobile robot are ensured.

Description

Technical field [0001] The invention relates to the field of mobile robots, in particular to a method and system for determining out-of-bounds of a mobile robot. Background technique [0002] With the continuous improvement of artificial intelligence technology, mobile robots have begun to develop toward autonomy and intelligence. Relying on the data of GPS, lidar, camera, ultrasonic and other sensors, some indoor service / sweeping robots with mobile functions can already realize self-positioning and construction of work area maps in specific areas. [0003] However, outdoors or in relatively open areas, due to the lack of feature points that can be used for positioning in the area, or due to problems such as weak positioning signals in the area, it is difficult to ensure that the robot can recognize it only by relying on sensors installed on the robot. The coordinate relationship with the working area is difficult to ensure stable and safe movement. In this environment, in tradit...
