Embodiment Construction

[0018] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention. Those skilled in the art can Adjust it as necessary to suit the specific application. For example, although the technical solution of the present invention is described by taking the full-sea depth autonomous remote-controlled submersible as an example in this specification, the products to which the technical solution of the present invention is applied are not limited to the full-sea-depth autonomous remote-controlled submersible. The technical solution can also be applied to other machines, and this change does not depart from the principle and scope of the present invention.

Abstract

The invention relates to the technical field of robots, in particular to a visual servo positioning and grabbing method, and aims to solve the problem in the prior art that the robot can not precisely position and grab a target object by self. The visual servo positioning and grabbing method comprises the following steps: acquiring an image of the target object; determining the position information of the target object in the image; determining the actual position of the target object in the environment according to the position information; and according to the actual position, controlling a manipulator of the robot to grab the target object. With adoption of the technical scheme, the robot efficiently and precisely positions and grabs the target object by self; and in addition, a hardware system of the robot does not need to be improved, so that limitation of the environment to the hardware system of the robot is lowered.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a visual servo positioning and grasping method. Background technique [0002] For a long time, due to the limitations of deep-sea exploration technology, the scientific community has limited understanding of deep-sea life, environment and geological processes. With the continuous breakthrough of deep-sea exploration technology, deep-sea science is becoming the latest frontier field of international marine science. Full-sea deep autonomous remote operated vehicle (ARV, Autonomous&Remotely operated Vehicle) provides an important technical means for scientists to carry out deep-sea frontier scientific research. Through full-sea deep ARV, it can realize large-scale high-precision detection and local fine sampling operations in deep sea areas. Scientists can Explore the origin, evolution and environmental adaptation mechanism of deep-sea species, study the basic environmental characte...
