Abstract
A kind of laser displacement inspecting device of video auxiliary, belongs to deflection of bridge span detection technique field.The present apparatus includes mobile bracket, laser, backboard, backboard bracket, camera, camera connecting rod, backboard is identified with transverse and longitudinal coordinate scale, laser is fixed on mobile bracket, backboard is fixed on backboard bracket, camera is fixed on camera connecting rod, and camera connecting rod is fixed on above backboard.Mobile bracket is fixed on target object when use, follows target object mobile, and the laser that adjustment backboard angle emits laser is vertical with backboard, captures laser point displacement automatically by camera to determine the displacement process of target object.The present apparatus determines the displacement process of target object in such a way that laser positioning and camera capture the displacement of laser positioning point, can improve detection accuracy with more intuitive determining target object moving process.
Description
Technical field
The utility model relates to a kind of laser displacement inspecting devices of video auxiliary, belong to deflection of bridge span detection technique neck
Domain.
Background technique
Amount of deflection is to evaluate the important indicator of bridge safty, directly reacts whether bridge structure deformation reaches risk range.
Deflection of bridge span instrument is the instrument for measuring amount of deflection, and flexometer can measure the variation of the vertical distance of object, be mainly used for bridge
Static, Dynamic flexural degree measurement, has extensive use in construction unit, unit in charge of construction and engineering detecting, supervisor.
Device, facility in existing market for amount of deflection detection are mainly photo-electric flexometer, photo-electric flexometer equipment
Complexity, imaging device is strongly professional, and accuracy is high, but there is also operate professional problem high, use cost is high simultaneously.This reality
With it is novel by means of video auxiliary propose a kind of displacement detector, it can be achieved that amount of deflection detection major function, with current valence
The more cheap picture pick-up device of lattice replaces professional Image-forming instrument, while easy to operate, has greatly saved installation cost, while again
Detection accuracy can be effectively ensured, have the characteristics that using easy, precision is high, at low cost.
Summary of the invention
The purpose of this utility model is the laser displacement inspecting device for proposing a kind of video auxiliary, by laser positioning and
The mode that camera captures the displacement of laser positioning point determines the displacement process of target object, can be with more intuitive determining object
Body moving process improves detection accuracy.
The utility model includes mobile bracket, laser, backboard, backboard bracket, camera, camera connecting rod, backboard
It is identified with transverse and longitudinal coordinate scale, laser is fixed on mobile bracket, and backboard is fixed on backboard bracket, and camera, which is fixed on, to be taken the photograph
As on head connecting rod, camera connecting rod is fixed on above backboard.
Bracket is moved when the utility model is used to be fixed on target object, is followed target object mobile, is adjusted backboard angle
The laser that degree emits laser is vertical with backboard, captures laser point displacement automatically by camera to determine the position of target object
Move past journey.
The utility model has the beneficial effects that
The utility model proposes a kind of laser displacement inspecting devices of video auxiliary, fill compared to existing displacement detecting
It sets, has using easy, precision is high, the remarkable advantages such as at low cost.
