Abstract
The utility model belongs to the technical field of automobile manufacture and detection, which relates to a calibration tool for three-dimensional optical detection. The calibration tool comprises a calibration plate and a fixed bracket for supporting the calibration plate. The calibration tool is characterized in that the calibration plate is a hard flat plate; the upper surface of the calibration plate is black; the fixed bracket comprises two or more brackets with the same size and structure; each bracket is at least provided with two grooves, wherein the widths of the grooves are matched with the thickness of the calibration plate; one groove is a vertical groove; two groove sides of the vertical groove are respectively perpendicular to the groove bottom mutually; the other groove is a chute; and one chute side of the chute is obliquely crossed with the chute bottom. According to the calibration tool disclosed by the utility model, the calibration efficiency and the calibration precision can be improved.
Description
Technical field
The utility model belongs to automobile making and detection technique field, relates to the three-dimensional calibration tool that detects usefulness of a kind of automotive part.
Background technology
Development along with the modern industry manufacture level, product parts adopts the irregular complex curved surface in a large number, links such as its design, production, detection, test need be carried out a large amount of digitizing of three-dimension curved surface entity and three-dimensional measurement, press for quick, efficient, accurate, portable three-dimensional measurement technology and counter inverting to designing technique.Adopted the three-dimensional optical detection system of two or two above video cameras, the workplace is often unfixing, in use or transportation, because vibration or other reasons, sometimes the angle between the video camera can change, thereby cause precision to change, thereby need often demarcate.How to improve demarcation efficient and just seem very important.
The utility model content
The purpose of this utility model is at above-mentioned existing problems, provides a kind of and can improve a kind of instrument of demarcating efficient and stated accuracy.Technical scheme of the present utility model is as follows:
A kind of calibration tool that is used for the three-dimensional optical detection comprises scaling board and the fixed mount that is used to support scaling board, and described scaling board is a hard plate, and its upper surface is a black; Described fixed mount comprises the support that two or more sizes are identical with structure, offers the groove that two groove widths and scaling board thickness are complementary on each support at least, and a groove is a vertical channel, and two trough rim is vertical mutually with bottom land respectively; Another groove is a skewed slot, one bar trough rim and bottom land oblique.
As preferred embodiment, the angle of described skewed slot is 60 °.
Adopt calibration tool of the present utility model, cooperate specific scaling method, can improve the precision and the efficient of timing signal.
Description of drawings
Fig. 1 is the structural representation of calibration tool of the present utility model.
Fig. 2 (a) is the structural representation of a support of scaling board fixed mount.Fig. 2 (b) is its front elevation.
Embodiment
Calibration tool of the present utility model comprises scaling board 1 and fixed mount 2 two parts, scaling board 1 is to be made with the duroplasts material, the surface spray black, fixed mount is the support 2 that the duroplasts of two elongate strip is made, length is at 200mm, and the groove that two groove widths and scaling board thickness are complementary is dug in the centre.A groove is a vertical channel 3, and two trough rim is vertical mutually with bottom land respectively, is used for vertically placing scaling board; Another groove is a skewed slot 4, and one bar trough rim or two trough rims and bottom land oblique are used for tiltedly placing scaling board, and the skewed slot of present embodiment is 60 ° of grooves.
When using calibration tool of the present utility model, measuring head is adjusted to certain height fixes, again scaling board is put on the fixed mount, height will with measuring head always, the calibration request according to plane template eight footworks moves fixed mount then, finishes demarcation.So-called eight footworks are exactly that the template image of gathering eight different azimuth is successively demarcated.Scaling method is as follows:
The first step is measured plate and is placed in the vertical channel, measures a plate range observation 1000mm;
Second step, measure plate and be placed in the vertical channel, measure a plate range observation 900mm;
The 3rd step, measure plate and be placed in the vertical channel, measure a plate range observation 1100mm;
The 4th step, measure plate and be placed in 60 ° of grooves, measure a plate range observation 1000mm;
The 5th step, measure plate and be placed in the vertical channel, measure a plate range observation 1000mm, measure plate and turn clockwise 90 °;
The 6th step, measure plate and be placed in the vertical channel, measure a plate range observation 1000mm, measure plate and turn clockwise 180 °;
The 7th step, measure plate and be placed in the vertical channel, measure a plate range observation 1000mm, measure plate and aim at left camera;
The 7th step, measure plate and be placed in the vertical channel, measure a plate range observation 1000mm, measure plate and aim at right camera.
Claims (2)
1. one kind is used for the calibration tool that three-dimensional optical detects, and comprises scaling board and the fixed mount that is used to support scaling board, it is characterized in that described scaling board is a hard plate; Described fixed mount comprises the support that two or more sizes are identical with structure, offers the groove that two groove widths and scaling board thickness are complementary on each support at least, and a groove is a vertical channel, and two trough rim is vertical mutually with bottom land respectively; Another groove is a skewed slot, one bar trough rim and bottom land oblique.
