Optical device and positioning system of robot

Abstract

The invention discloses an optical device and a positioning system of a robot. The optical device comprises a transmitting optical assembly and a receiving optical assembly, wherein the transmitting optical assembly is used for transmitting a detection signal; and the receiving optical assembly is not arranged on the same optical axis as the transmitting optical assembly, comprises a detector anda first receiving mirror and a second receiving mirror which are different in focal length, and is used for determining positioning information of the robot according to reflection signals and detection signals of a target object detected by means of the first receiving mirror and a target object detected by means of the second receiving mirror. Therefore, the problems that no matter whether a co-optical-axis mode is adopted or an off-axis mode non-coaxial with a transmitting-receiving optical path is adopted, the use requirements of the measurement precision and the overall structure cannot be met at the same time, complex and variable environments cannot be timely and effectively dealt with, and the use performance of the robot cannot be reduced are solved.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to an optical device and a positioning system of a robot. Background technique [0002] At present, laser radar, such as the two-dimensional laser radar used in indoor construction robots, is like the human eye, realizing the functions of indoor positioning and obstacle avoidance of robots, but the near-field detection blind spots of laser radar are too many, and it cannot be timely and effectively Coping with the complex and changeable indoor environment will lead to the decline of the performance of indoor construction robots. [0003] In related technologies, the optical path of the two-dimensional laser radar mainly adopts a common optical axis method in which the transmitting and receiving optical paths are on the same axis, and an off-axis method in which the transmitting and receiving optical paths are not coaxial. Among them, the blind area range of the common optical a...
