Articulated engineering machinery, panoramic look-around system and calibration method thereof

Abstract

The invention relates to an articulated engineering machine, a panoramic look-around system and a calibration method thereof. The articulated engineering machine comprises at least two articulated structure sections which are sequentially connected through an articulated frame (3), the at least two articulated structure sections comprise the first articulated structure section (1), and the first articulated structure section comprises a first vehicle body (11) and a cab (12) arranged on the first vehicle body (11); the panoramic look-around system comprises a plurality of shooting parts (6) which are installed on a first hinge structure section (1) and configured to shoot the environment around the hinge type engineering machine; an image processing component (8) which is configured to receive the images shot by the plurality of shooting components (6) and splice the images into a look-around image of the whole circumference of the first hinge structure section (1); and a man-machine interaction component (9) which is configured to display the panoramic image formed by splicing the image processing components (8).

Description

technical field [0001] The present disclosure relates to the technical field of construction machinery driving assistance, and in particular to an articulated construction machinery, a panoramic view system and a calibration method thereof. Background technique [0002] The development of modern science and technology has greatly promoted the intelligence of construction machinery, and more and more high-end technologies have been introduced into the field of construction machinery, making construction machinery move towards more efficient and safer goals. Usually construction machinery can only rely on rearview mirrors or reversing images to assist in observing the surrounding environment during the construction process. However, due to the existence of obstacles such as the front of the car, windows, and pillars, and the generally high view of the construction machinery cab, the driver There are blind spots in the field of vision, and it is impossible to judge whether ther...

AI Technical Summary

Problems solved by technology

Usually construction machinery can only rely on rearview mirrors or reversing images to assist in observing the surrounding environment during the construction process. However, due to the presence of obstacles such as the front of the car, windows, and pillars, and the generally high view of the construction machinery cab, the driver There is a blind area in the field of vision, and it is impossible to judge whether there are obstacles in the occlusion area and the distance between obstacles

[0003] Moreover, in order to improve the flexibility of steering and operation of construction machinery, there have been construction machinery in which the cab and the rear frame are connected through a hinge mechanism. During the steering process of construction machinery, the angle of the rear frame relative to the cab is constantly changing. Therefore, it is more difficult for the driver to judge the environment around the construction machinery, which increases the difficulty of operation and makes it difficult to ensure the safety of the driving process.
