触三次元測定装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-contact three-dimensional measuring device, and more particularly to a non-contact three-dimensional measuring device for three-dimensionally measuring industrial mass-produced products by using a surveying instrument such as a theodolite or a total station.

三次元測定が行われている。On the other hand, in recent years, a three-dimensional measurement of a large structure such as a bridge or an aircraft has been performed using a surveying instrument such as a total station.

に測定点が存在するとき測定点の動きに合わせて測量機
を駆動する追尾などの機能を測量機に持たせた。However, in the case of three-dimensional measurement by a surveying instrument, it is necessary for the operator to collimate the measuring point himself, and if there are many measuring points, the burden on the operator will be significantly increased. It has functions such as searching and tracking, and the collimation work is automated. In other words, in order to perform automatic collimation by the surveying instrument instead of collimation by the operator's visual inspection, when there is no measuring point in the field of view of the telescope, the search or telescope that drives the surveying instrument until the measuring point is found The surveying instrument has functions such as tracking to drive the surveying instrument according to the movement of the measuring point when the measuring point exists in the field of view.

【発明が解決しようとする課題】ところが、測定点の捜
索や追尾による自動視準では、視準精度が５″以上であ
り、三次元測定には精度が足りない。However, in the automatic collimation by the search or tracking of the measurement point, the collimation precision is 5 ″ or more, and the precision is insufficient for the three-dimensional measurement.

することにより解決できるが、非常にコストが高くなる
という問題があった。When the automatic collimation is performed by using image processing, the collimation accuracy is improved to about 1 ″, but when a wide field of view is used to search for a measurement point, the resolution of the image pickup element is relatively deteriorated, and the tracking performance is reduced. Therefore, if high-speed performance is prioritized, calculation processing cannot be performed sufficiently.These problems can be solved by using a high-grade image pickup element and calculation element, but there is a problem that the cost becomes very high.

If the width of the line 14 is set to, for example, 10 mm, and this width is set within the allowable range of installation error, it serves as a guide. The positional relationship between the line 14 and the known point targets 11 and 12 is known.

4). The collimation work here may be performed manually or may be performed by automatic collimation by image processing. Since the measurement object 13 is roughly aligned in advance, even if the installation error of 10 mm and the manufacturing error of 15 mm are combined, the error is within about 30 mm. Therefore, when the angle is converted at a distance of 10 m from the measurement object 13, 10 is obtained. If the angle of view for image detection is larger than this (for example, 1 °), image processing can be performed, and thus a large-scale search is not required.

Based on the design data read from the CAD system 3, the measurement object 13 is directed to a plurality of design points on one end surface.
As described above, since the measurement point target 16 is attached to the bolt hole of the measurement object 13, when the telescope of the total station 1 is aimed at the design point of the measurement object 13,
The measurement point target 16 enters the field of view. At this time, the distance between the instrument point of the surveying instrument and the design point of the measuring object 13 is obtained as focusing data based on the instrument point of the surveying instrument and the design data. That is, since the positional relationship with the measurement object is known from the instrument point of the surveying instrument determined in step 102, the distance (focusing data) from the instrument point of the surveying instrument to the design point can be calculated. . Then, this focusing data is stored in the automatic focusing unit 20 in association with the design data read from the CAD system 3. Therefore, when the center of the telescope faces the design point of the measuring object 13, the automatic focusing unit 20 is operated based on the design data and the focus data of the design point to perform focusing. Further, since the total station 1 is provided with the distance measuring unit 4, when the center of the telescope faces the design point of the measuring object 13, the CPU 10 controls the distance measuring unit 10 to perform distance measurement, It is also possible to operate the automatic focusing section 20 based on the distance measurement data to focus. The field of view is captured by the CCD camera of the image capturing unit 5 (S106).

The image processing unit 6 calculates the amount of deviation on the image due to the video signal based on the coordinates of the center of the image signal 6. When the measurement is completed for all of the plurality of design points, the process returns to step 104 and the same measurement is repeated for the other measurement object 13.
