Abstract
The invention discloses a cross cursor for automobile position and posture detection, aiming to solve the problem of lack of suitable markers for automobile position and posture detection. The cross cursor for automobile position and posture detection mainly comprises steel rods (1), nine iron rings (2), nine light-emitting diodes (3) and four magnets (4), wherein the nine iron rings (2) are arranged crossly in central symmetry, the nine light-emitting diodes (3) penetrate through inner holes of the nine iron rings (2) and are fixedly in interference fitting with the iron rings (2), the four magnets (4) are arranged crossly in central symmetry, and each of four of the steel rods (1) is fixedly welded between every magnet (4) and each of four outmost iron rings (2) while each of the rest of the steel rods is fixedly welded between every two adjacent iron rings (2). The cross cursor for automobile position and posture detection has the advantages of small occupied area, simple structure, high detection precision, simplicity and convenience in operation, easiness in mounting, low in cost and reliable performance.
Description
Technical field
The present invention relates to the annex of a kind of automobile position posture detection device, in particular, it is a kind of vapour
Truck position attitude detection tracking cross.
Background technology
For ensureing the safety traffic of automobile, the most quickly automobile is pacified by position and the athletic posture of detection automobile
Full property is significant.The position and attitude using Machine Vision Detection automobile has the feature of non-cpntact measurement,
And the accuracy and speed of detection is had a significant impact by the marker of automobile, it is therefore desirable to a kind of simple in construction of design,
The automobile logo thing that easy for installation, known quantity is many, it is achieved the accuracy detection to automobile pose.
Summary of the invention
The problem that the present invention is directed to vehicle body position and attitude detection marker, it is provided that a kind of simple in construction, operation
Easy, be easily installed, cost is relatively low, the automobile position attitude detection tracking cross of dependable performance.Automobile position
Put attitude detection tracking cross and identified structure by the multi-characteristic points of the cross distribution of known distance determined by steel pole
Become, it is achieved the representation function to vehicle body position and attitude.
Refering to Fig. 1 to Fig. 2, for solving above-mentioned technical problem, the present invention adopts the following technical scheme that and is achieved.
Automobile position attitude detection tracking cross provided by the present invention include steel pole, iron hoop, light emitting diode with
Magnet.
Nine iron hoop Central Symmetry crosses are arranged, are wherein welded and fixed with a steel pole between each two iron hoop even
Connecing, nine light emitting diodes penetrate that the endoporus of nine iron hoops is fixing with iron hoop interference to be connected, four magnetic blow out centre
Symmetrical cross is arranged and with a steel pole be welded and fixed each with between outermost four iron hoops is connected.
Steel pole described in technical scheme is the hard parts that standard steel pole is made.
Iron hoop described in technical scheme is steel annular part.
Magnet described in technical scheme is the cylindric part of magnetic.
The invention has the beneficial effects as follows:
(1) present invention uses lever to connect each parts, two parts fixed due to hard parts steel pole
Between distance known and will not change, therefore can carry out visual modeling as known a priori condition, simplify
The computing of vehicle body pose.
(2) present invention uses light emitting diode to constitute cross vapour with the connected mode of iron hoop interference fit
Car marker, iron hoop lighter weight, the shape of marker is easy to identify and measure, is used four blocks of magnet to realize
The Fast Installation of cross marker, is greatly saved the time of operation.
Accompanying drawing explanation
Fig. 1 is the shaft side figure of automobile position attitude detection tracking cross；
Fig. 2 is the steel pole 1 of automobile position attitude detection tracking cross, iron hoop 2 and light emitting diode 3 local axle
Mapping；
In figure: 1. steel pole, 2. iron hoop, 3. light emitting diode, 4. magnet.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings:
Refering to Fig. 1 to Fig. 2, automobile position attitude detection tracking cross includes steel pole 1, iron hoop 2, luminescence
Diode 3 and magnet 4.
The flexible part that steel pole 1 is made for standard steel pole, iron hoop 2 is steel annular part, and magnet 4 is magnetic
Property cylindric part, nine iron hoop 2 Central Symmetry crosses arrange, wherein between each two iron hoop 2 with one
Steel pole 1 is welded and fixed connection, and nine light emitting diodes 3 penetrate endoporus and iron hoop 2 interference of nine iron hoops 2
Fixing connection, four magnet 4 Central Symmetry crosses are arranged also and each with one between outermost four iron hoops 2
Individual steel pole 1 is welded and fixed connection.
The using method of automobile position attitude detection tracking cross:
Automobile position attitude detection tracking cross is fixed on car body by magnet, lights light emitting diode,
Nine light emitting diode lights can be extracted by the image of nine light emitting diodes of camera acquisition during motor racing
Dot center position, as the measurement characteristic point of automobile pose, utilizes the condition of the steel pole length of known rigidity to build
Vertical vision-based detection model, and then obtain the attitude parameter of vehicle body, it is achieved the detection function of vehicle body pose.
