Abstract
The utility model discloses a dual-lens image measurement instrument. The dual-lens image measurement instrument comprises a detection table and a first lens can be used to perform local high-precision scanning. The first lens is installed on a movable rack. The movable rack is slideably installed on the detection table relative to the detection table. The movable rack is further provided with a second lens can be used to perform large-scale scanning. The second lens is located beside the first lens. Thus, the position of an element to be measured can be scanned firstly with the second lens in a large-scale scanning manner, and then high-precision scanning is performed with the first lens, so both of the fast scanning function and the high-precision detection function can be realized, so that the measurement process is more convenient.
Description
Technical field
The utility model relates to imager art, refers in particular to a kind of twin-lens video measuring instrument.
Background technology
Along with scientific and technological progress, use visual pattern to detect more and more general in automated production, visual pattern detects directly and replaces human eye measure and judge with machine, and the accuracy rate of measurement is higher, and testing cost is effectively reduced.But, because visual pattern detects, belong to mechanization running, while detecting, element under test must drop in the coverage of image-pickup device (two kinds of point CMOS and CCD), and product needed, in relatively static state, just can photograph image clearly.The image absorbing is more clear, and false drop rate is lower.
Traditional image measurer generally comprises CCD camera, light source and detection table top, by this CCD camera, the element under test of specific position is carried out to high-precision image capture.This image measurer is only installed single CCD camera lens, can only obtain local, image among a small circle, and therefore its effect can only be small articles to picture, cannot scan the entirety of large workpiece.When the topography to large workpiece absorbs, need manually certain position to be measured of workpiece is moved in the coverage of camera lens, this manually-operated mode takes time and effort very much, and detection speed is slow, has restricted production efficiency.
Utility model content
In view of this, the utility model is for the disappearance of prior art existence, and its fundamental purpose is to provide a kind of twin-lens video measuring instrument, takes into account rapid scanning and high-precision measuring ability, makes to measure convenient.
For achieving the above object, the utility model adopts following technical scheme:
A kind of twin-lens video measuring instrument, comprise the first camera lens that a monitor station and can local high-precision scanning, this first camera lens is installed on a movable machine frame, this movable machine frame relatively monitor station is installed on monitor station slidably, on this movable machine frame, be also provided with one can large area scanning the second camera lens, this second camera lens is positioned at by the side of the first camera lens.
Preferably, described the first camera lens is face image capture device, and described the second camera lens is linear image intake device.
Preferably, described movable machine frame comprises vertical supporting arm and the cross-brace arm of integral type, and this cross-brace arm sling is in the top of monitor station.
Preferably, described the second camera lens is hung on cross-brace arm.
Preferably, described the first camera lens has sleeve outward, and this second camera lens is fixed on sleeve.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, it is mainly by other second camera lens that increases of the side at the first camera lens, can be first with the position of the second camera lens large area scanning element under test, then use the precision measure of first mirror head height, thereby can realize rapid scanning and high precision measuring ability, can effectively improve detection efficiency, increase the convenience detecting.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.

Embodiment
Please refer to shown in Fig. 1 to Fig. 2, the concrete structure that it has demonstrated the preferred embodiment of the utility model, includes a monitor station 10, one first camera lens 20 and one second camera lens 30.
Wherein, outside described the first camera lens 20, there is a sleeve 21.This first camera lens 20 is installed on a movable machine frame 40, and this movable machine frame 40 relatively monitor station 10 is installed on monitor station 10 slidably.Described movable machine frame 40 comprises vertical supporting arm 41 and the cross-brace arm 42 of integral type, and this cross-brace arm 42 is suspended from the top of monitor station 10.The first camera lens 20 is installed on the bottom surface of cross-brace arm 42, thereby the first camera lens 20 can be just to 10 of monitor stations.
Described the second camera lens 30 can directly be installed on sleeve 21, or hangs in the bottom surface of cross-brace arm 42, and this second camera lens 30 is positioned at by the side of the first camera lens 20.In the present embodiment, this first camera lens 20 is first used face image capture device, can detect image among a small circle high-precisionly, and this second camera lens 30 is selected linear image intake device, thus can large area scanning the position of to be detected.
When needs detect on a large scale, as Figure 1-3, element under test 50 is placed on monitor station 10, by driving mechanism (motor or cylinder etc.), drive relative monitor station 10 translations of movable machine frame 40, thereby drive the first camera lens 20 and the second camera lens 30 to move on monitor station 10, mode (or from right to left) large area scanning element under test 50 from left to right by this second camera lens 30 with linear sweep 31, and the each concrete position 51(that will be detected by system log (SYSLOG) element under test 50 is such as hole, components and parts, concane gap etc.) position.When carrying out high definition detection to part among a small circle, by the selected accurately some concrete position 51 of measurement that needs of control system, then with the first camera lens 20, be displaced to the just top to this concrete position 51, this is carried out pointedly to high-acruracy survey, the detected value of high-acruracy survey comprises size, internal-and external diameter, outer shape defect etc.
In sum, design focal point of the present utility model is, it is mainly by other second camera lens 30 that increases of the side at the first camera lens 20, can be first with the position of the second camera lens 30 large area scanning element under tests, use again the first camera lens 20 high-acruracy surveys, thereby can realize rapid scanning and high precision measuring ability, can effectively improve detection efficiency, increase the convenience detecting.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
