[0025] Such as figure 1 As shown, the measuring machine of the first embodiment has: a measuring machine body 1, a telescope optical system 10, a first collimating optical system 30, and a second collimating optical system 110. The light source 29 in the machine body 1 emits the reflected light sent by the angular cube (measuring point) 60, detects the position of the angular cube 60 on the image sensor 50, and moves the measuring machine body according to the position information so that the angular cube 60 is located at Collimation within the field of view of the telescope optical system 10 (second collimation optical system 110 ).
[0026] Here, the first collimation optical system 30 is used to make the reflected light emitted by the corner cube 60 enter the telescope optical system 10 or the second collimation optical system before the telescope optical system 10 or the second collimation optical system 110 performs collimation. The field of view of 110 is composed of an...

[0043] In this embodiment, the same components as those in the first embodiment are denoted by the same symbols.
[0044] Such as Figure 6 As shown, the first collimating optical system 80 has: an omnidirectional reflector 70 that is arranged on the upper part of the measuring machine body 1 and can incident light of at least the entire hemisphere of the measuring machine body 1 , and is used for imaging on the image sensor 52 An imaging lens 71 for imaging and a prism 72 for collimating light. In this structure, the light beam emitted by the light source 79 installed above the omnidirectional reflector 70 is reflected by the collimation light prism 72 provided on the omnidirectional reflector 70, and is emitted to the outside of the measuring machine. On the other hand, the light beam incident on the omnidirectional reflector 70 from the outside of the measuring machine is reflected by the omnidirectional reflector 70 and is imaged on the image sensor 52 by the imaging lens...
no. 3 approach
[0057] In this embodiment, the same components as in the first embodiment are denoted by the same symbols.
[0058] Such as Figure 7 As shown, in the third embodiment, there is a collimation optical system 130 instead of the first collimation optical system 30 and the second collimation optical system 110 in the first embodiment. That is, the collimating optical system 130 is composed of an objective lens 11, a light source 19, a prism 12 for collimating light, a branch prism 13, and an image enlargement mechanism 90, wherein the objective lens 11, the light source 19, the prism 12 for collimating light, and the branching prism 13 are closely related to the telescope optics. System 10 is shared.
[0059] In the collimating optical system 130, the collimating optical system 130 can be switched from wide-angle to telephoto through the image magnification mechanism 90 provided between the branch prism 13 and the image sensor 50. After reflection, an image is formed on the imag...
