Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
Visual angle, the foot type three-dimensional vision information system foot front light path schematic diagram that Fig. 1 provides for the utility model, visual angle, the foot type three-dimensional vision information system foot side light path schematic diagram that Fig. 2 provides for the utility model.In Fig. 1 and Fig. 2, each arrow represents the direct of travel of light, and the dotted line of same type represents same light path.Shown in composition graphs 1 and Fig. 2, this foot type three-dimensional vision information system comprises the relatively-stationary video camera 2 in position each other, projecting apparatus 1, first speculum 3 and the second speculum 4.Projecting apparatus 1, for projected fringe light, can be any striped light that can be used for three-dimensional measurement, as phase shift striped light and strip encoding light as required.Also can be other structured lights.
The striped light that projecting apparatus 1 projects comprises some parts, the i.e. surface towards projecting apparatus 1 of foot to be measured 5 that directly projects to of some striped light, some striped light has projected to the surface of the rear projection instrument 1 of foot 5 to be measured after the first speculum 3 and the reflection of the second speculum 4.For ease of describing, can be regarded as striped light and comprise some parts, each several part is respectively with descriptions such as Part I, Part II, Part III.
The first surface that the Part I of striped light projects to foot 5 to be measured from first direction forms the first projected fringe, and the direct camera 2 being shot of the first projected fringe gathers.The second surface that the Part II of striped light projects to foot 5 to be measured from second direction after the first speculum 3 reflects forms the second projected fringe, and the second projected fringe camera 2 being shot after the first speculum 3 reflects gathers.The 3rd surface that the Part III of striped light projects to foot 5 to be measured from third direction after the second speculum 4 reflects forms the 3rd projected fringe, and the 3rd projected fringe camera 2 being shot after the second speculum 4 reflects gathers.
As seen from Figure 1, by rationally arranging the relative position of the first speculum 3, second speculum 4, projecting apparatus 1, video camera 2 and foot to be measured 5, the striped light of three direction projections just can be made to be realized covering completely by the perimeter surface of instep to sole to foot together, and namely the first projected fringe, the second projected fringe and the common complete covering of the 3rd projected fringe foot 5 to be measured are by the perimeter surface of instep to sole.When arranging, the optical axis of projecting apparatus 1 and the optical axis included angle of video camera 2 can be set to 20 to 40 and spend, generally desirable 30 degree.
After setting said structure, also need to demarcate this three-dimensional vision information system.From Fig. 1 and Fig. 2, this system can be regarded as and is made up of three subsystems, the first subsystem be made up of projecting apparatus 1 and video camera 2 respectively, the second subsystem be made up of projecting apparatus 1, video camera 2 and the first speculum 3 and the 3rd subsystem be made up of projecting apparatus 1, video camera 2 and the second speculum 4.Each subsystem carries out three-dimensional measurement from a direction to foot 5 to be measured respectively, therefore, needs to demarcate three subsystems respectively.
Need based on demarcation, this three-dimensional vision information system also can comprise the stereo target for demarcating, and stereo target comprises two relatively-stationary plane target drones, and the target surface coordinate system of two plane target drones is parallel to each other.Feature on plane target drone is formed by getting through hole on plane target drone, thus guarantees the parallel relation of two coordinate systems.Particularly, stereo target can be platy structure, and two plane target drones, on the two sides of platy structure, can determine the relative position relation of two plane target drones according to the thickness of plate, desirable 2 millimeters of the thickness of plate.Stereo target is arranged on the position of foot 5 to be measured, and makes one of them plane target drone in the face of projecting apparatus 1, another plane target drone is back to projecting apparatus 1.Carry out timing signal, the striped light that projecting apparatus 1 projects directly will project to one of them plane target drone from first direction, project to another plane target drone from second direction and third direction.Along the equidistant moving target mark in vertical line direction, target face, project phase shift striped and strip encoding simultaneously, just can pass through multinomial implicit calibration method, realizes respectively demarcating simultaneously, thus complete the demarcation to this three-dimensional vision information system to three subsystems.
After demarcation completes, just can realize carrying out three-dimensional measurement by instep to the perimeter surface of sole to foot 5 to be measured from three directions simultaneously.The first projected fringe received by video camera, the second projected fringe and the 3rd projected fringe input computer system, just can obtain the three-dimensional data of foot to be measured through network analysis process.Because demarcation and measuring process are all carried out based under an overall world coordinate system, therefore, it is very fast that native system demarcates speed, and in measurement, the measurement data in three directions does not need to find match point and carries out data splicing, directly carry out the three-dimensional data that data fusion can obtain foot, substantially increase certainty of measurement and speed.Meanwhile, native system only needs a projecting apparatus 1 and video camera 2, reduces measurement cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
