Abstract
The utility model relates to an on-line measuring system of an automotive frame. The on-line measuring system comprises a computer host. The computer host is connected with a displayer, a controller and CCD cameras. The controller is connected with a laser light source. The number of the CCD cameras is two, and the two CCD cameras are arranged at two sides of the laser light source. The laser light source and the CCD cameras are arranged below the automotive frame. The on-line measuring system of the automotive frame has the advantage of con-contact, high-speed and high-precision measuring characteristics. The measuring system has a wide application potential. The on-line measuring system can be used to measure the automotive frame, and can also be used to measure the body shape of an automobile. Through improvement, the expansion of the system as a distance detecting system is relatively easy to realize. The system is capable of providing necessary surrounding information to realize intelligent auxiliary driving functions such as an auxiliary braking function and a proximity warning function.
Description
Technical field
The utility model relates to a kind of automotive frame on-line measurement system.
Background technology
Automotive frame plays the effect of bearing vehicle body, and the size of automotive frame, profile all have the specification of standard, in order to guarantee the safety of vehicle, can be arranged on vehicle just the automotive frame of producing all will carry out strict detection to its profile, size and performance.
But the precision of some present measurement mechanisms does not reach requirement, often makes measurement result error occur, for the safe handling of vehicle production and vehicle has brought potential safety hazard.
The utility model content
The utility model proposes a kind of automotive frame on-line measurement system, have noncontact, high speed and high-acruracy survey characteristic have made up weak point of the prior art.
The technical solution of the utility model is achieved in that
A kind of automotive frame on-line measurement system, comprise host computer, described host computer is connected with display, controller and CCD camera, be connected with a LASER Light Source on described controller, described CCD camera is two, be positioned at the both sides of described LASER Light Source, described LASER Light Source and described CCD camera are positioned at the below of automotive frame.
The beneficial effects of the utility model are: have noncontact, high speed and high-acruracy survey characteristic.This measuring system is with a wide range of applications.Not only can the measured automobiles crossbeam, also can measured automobiles car body profile.By improving, this systematic comparison easily expands to the distance measurement system.For realizing that the auxiliary function of driving of intelligence provides necessary ambient condition information.Assist brake function and near warning function for example.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structured flowchart of the described automotive frame on-line measurement system of the utility model embodiment;
Fig. 2 is the measurement procedure figure of the described automotive frame on-line measurement system of the utility model embodiment.
In figure:
1, host computer; 2, display; 3, controller; 4, CCD camera; 5, LASER Light Source; 6, automotive frame.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the described automotive frame on-line measurement system of the utility model embodiment, comprise host computer 1, described host computer 1 is connected with display 2, controller 3 and CCD camera 4, be connected with a LASER Light Source 5 on described controller 3, described CCD camera 4 is two, is positioned at the both sides of described LASER Light Source 5, and described LASER Light Source 5 and described CCD camera 4 are positioned at the below of automotive frame 6.
If 2 are depicted as the measurement procedure figure of the described automotive frame on-line measurement system of the utility model embodiment, in order to realize high-acruracy survey, at first to correct optical imaging system.Correct content and comprise that mainly in face, distance is corrected, principal point aligning and imaging len bending differ rectification.Then position and the degree of tilt of image are demarcated.On this basis, resolve the vertical distribution height of sample by means such as coordinate transforms.In conjunction with two-dimensional image information, finally synthetic 3D shape distributes.
This system adopts photogrammetric technology, and the 3D shape that detects automotive frame distributes.Developing by leaps and bounds of digital imaging system and computing machine processing capacity realizes that high speed, high-precision three-dimensional shape measure become possibility.Several pieces of testing sample surface images are taken from different viewpoints by this system, process through image, calculate the three-dimensional of parsing sample and highly distribute.Throw identifier on image by laser projector, measuring accuracy can be brought up to 0.05mm.In order to improve the system data analytic ability, adopt the parallel data processing capacity of image processor, realize the high speed image conversion.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
