Problems solved by technology

On the one hand, it reduces the intelligence of the system; on the other hand, vehicle bumps affect the focusing device of the digital camera, which disturbs the image acquisition
To sum up, the existing technical conditions limit the application of machine vision technology in the intelligent detection of highway tunnels. The root cause is the lack of a set of image stabilization acquisition devices, resulting in poor quality of the collected images, which affects subsequent image processing and features. identify

Abstract

The invention relates to a car-mounted adjustment platform used for tunnel image acquisition and the implementation method thereof. The platform comprises an installation platform, motion branches, a base and a rotary driver. There are three motion branches, two of which are in the form of an SPR structure and the rest in the form of a PRS structure. The motion branches are connected with the base; the base is connected with a vehicle luggage carrier through a rotary platform. The rotary platform is capable of rotating under the drive of a stepper motor. Compared with the prior art, the invention possesses the ability to move along the longitudinal direction of the tunnel so that what is between a digital camera and the tunnel lining surface stays within the depth-of-field of the camera and that the vertical height of the digital camera could be adjusted in real time. In addition, the application of parallel robots in the field of highway tunnel image acquisition prevents the influence of vehicle trajectory deviation on the image acquisition equipment. At the same time, the spatial position of the digital camera can be adjusted according to the tunnel structure size, therefore, solving a plurality of difficult technical problems of an existing image acquisition system used in road tunnels.

Description

technical field [0001] The invention belongs to the technical field of road detection, and in particular relates to a vehicle-mounted adjustment platform for tunnel image acquisition and an implementation method thereof. Background technique [0002] Due to geological disasters, operating years and other reasons, expressway tunnels will have cracks, which seriously threaten the operation safety of expressways. At present, tunnel crack detection methods and equipment are still relatively backward, and manual or manual instruments are often used to complete the detection task with the help of aerial vehicles. This method based on manual detection is inefficient and highly subjective, especially in the case of a number of new super-long tunnels in my country, and it is impossible to complete the detection task in a short period of time by relying on manual labor. [0003] The core and key of machine vision technology is how to acquire high-quality images, which requires that t...
