Embodiment Construction

[0024] The technical solutions of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0025] The present invention provides a kind of method utilizing 2D radar to realize space detection, and it comprises the following steps:

[0026] 1) When the moving speed of the moving subject is relatively slow, such as figure 1 and figure 2 As shown, on the front of the moving body, a 2D laser radar 1 is arranged along the vertical or horizontal direction of the moving body.

[0027] When the moving speed of the moving subject is relatively fast, such as image 3 As shown, two 2D laser radars 1 are arranged in parallel along the vertical direction of the moving body, and at least one 2D laser radar 1 is arranged along the horizontal direction of the moving body.

[0028] The rotating part 2 is arranged on the moving body, the number of the rotating parts 2 is the same as that of the 2D laser radar 1, the 2D laser radar 1 is conn...

Abstract

The present invention relates to a method of utilizing a 2D radar to realize space exploration. The method comprises the following steps of setting a 2D laser radar and a rotating part on a mobile main body; setting a power supply module, a main control module, a signal processing module and a driving module in the mobile main body, wherein the power supply module supplies a working voltage to the main control module, the 2D laser radar is connected with the rotating part, and the rotating part is connected with the main control module via the driving module; using the main control module to drive the rotating part to rotate up and down or left and right around the right side of the mobile main body via the driving module, using the rotating part to drive the 2D laser radar to rotate, and using the 2D laser radar to send a detected electromagnetic wave which is emitted back by a front barrier to the signal processing module; using the signal processing module to process the received electromagnetic wave and then send to the main control module, and using the main control module to calculate the orientation and distance information of the front barrier. According to the present invention, the 2D laser radar can be utilized to finish the omnibearing detection in front of the mobile main body.

Description

technical field [0001] The invention belongs to the technical field of radar detection, and in particular relates to a method for realizing space detection by using 2D radar. Background technique [0002] Laser ranging radar has been used more and more in military, aviation and civil fields due to its advantages of fast ranging speed, high precision, and intuitive information acquisition. In the research of intelligent mobile robots, LiDAR, together with CCD cameras and ultrasonic sensors, has become one of the indispensable external environment perception sensors for robots. [0003] At present, there are mainly two types of laser ranging radar: two-dimensional and three-dimensional. Two-dimensional laser radar only obtains distance information on a fixed scanning plane, also known as single-line scanning; Rotating the scan plane, also known as multi-line scanning. Compared with two-dimensional laser radar, because three-dimensional laser radar can directly and quickly ob...
