Embodiment 1

[0031] Embodiment 1: When the number of cameras is one, the corresponding attitude sensor and storage box are one, and the camera shake compensation device for tunnel image acquisition includes a tunnel inspection vehicle, attitude sensor, camera, storage box, Trigger signal board, signal acquisition box, synchronous controller, acquisition controller and storage box; The camera and the attitude sensor are fixed on the same horizontal plane of the same detection platform, and the attitude sensor and the trigger signal board are both Connected with the signal acquisition box; the signal acquisition box is connected with the synchronization controller, the synchronization controller is connected with the camera and the acquisition controller respectively, and the acquisition controller is connected with the storage box connected; the trigger signal board is used to generate a trigger signal to trigger the camera, and the attitude sensor is used to provide the attitude signal obta...

Embodiment 2

[0032] Embodiment 2: When there are multiple and even numbers of cameras, the number of corresponding attitude sensors and cameras is the same, the number of corresponding acquisition controllers and storage boxes is half of the number of cameras, and the synchronization controller will trigger the signal Divided into multiple trigger signals, so that multiple trigger signals can simultaneously trigger multiple cameras to collect tunnel images at the same time, and send the collected images to the acquisition controller; while the cameras are collecting images, the synchronization controller sends sensor data to the acquisition controller Multiple cameras are arranged in a semicircular arc, and each camera has a one-to-one corresponding attitude sensor fixed on the same horizontal plane of the same detection platform; the camera is an area array CCD camera; the attitude sensor also includes a built-in gyroscope , the built-in gyroscope is used to detect the x / y / z three-axis ang...

Embodiment 3

[0033] Embodiment 3: When there are multiple cameras and an odd number, the cameras are arranged in a semi-circular arc, the diameter side of the semi-circular arc is parallel to the tunnel road surface, and one of the cameras is located at the highest point of the semi-circular arc, and each camera There is a one-to-one corresponding attitude sensor fixed on the same horizontal plane of the same detection platform, and each camera has a one-to-one corresponding synchronous controller, and all cameras and synchronous controllers share one acquisition controller; the corresponding navigation The number of attitude sensors and cameras is the same, and the number of corresponding acquisition controllers and storage boxes is half of the number of cameras plus 1. The synchronization controller divides the trigger signal into multiple trigger signals, so that multiple trigger signals can simultaneously trigger multiple The camera collects tunnel images at the same time, and sends the...

Abstract

The invention provides a camera shake compensation device and method for tunnel image acquisition. The camera shake compensation device comprises a tunnel detection vehicle, at least one navigation attitude sensor, at least one camera, at least one storage box, at least one trigger signal board, a signal acquisition box, at least one synchronous controller, at least one acquisition controller anda storage box; the camera and the navigation attitude sensor are fixed on the same horizontal plane of the same detection platform; the navigation attitude sensor and the trigger signal board are connected with the signal acquisition box; the signal acquisition box is connected with the synchronous controller, the synchronous controller is respectively connected with the camera and the acquisitioncontroller, and the acquisition controller is connected with the storage box; the camera shake compensation in the high-speed movement process is realized; the angle offset of the camera is calculated through the inclination angle signal, the azimuth angle signal and the built-in gyroscope signal collected by the navigation attitude sensor, so that the image shot by the camera at the corresponding time position is subjected to jitter compensation, and the definition of the information of the image collected by the camera is ensured.

Description

technical field [0001] The present invention relates to the technical field of tunnel defect detection, in particular to a camera shake compensation device and method for tunnel image collection for tunnel detection data. Background technique [0002] Tunnel defect detection is carried out in a high-speed operating environment, and the image data collected by the camera is very large. Not only must the camera’s collection speed be ensured, but in the current existing technology, when using the camera to take pictures due to hand shake or its location For the vibration generated when the platform moves, there are generally several anti-shake methods including optical anti-shake, electronic anti-shake and sensory device (CCD) anti-shake; Chinese patent literature (application number: 200910067505.9) proposes an airborne imaging device image Shake compensation method, this method uses the rate gyroscope to measure the angular motion velocity of the visual axis of the CCD camera...
