Problems solved by technology

The system has the characteristics of high measurement accuracy and fast point touch measurement speed; however, its attitude measurement accuracy is affected by background stray light, spherical aberration of the imaging system, and the shape of the light source on the probe; and the length of the probe rod is also limited. It is only suitable for short-distance measurement and cannot meet the needs of long-distance measurement of large equipment

Embodiment Construction

[0019] Further detailed description will be given below in conjunction with the accompanying drawings.

[0020] see figure 1 The combined non-contact spatial coordinate measuring device of the embodiment of the present invention includes a total station 1, a laser electronic target 2, a laser displacement sensor 3, a spoke groove laser electronic target fixing plate 4 and a spoke groove laser displacement sensor fixing plate 5 and computer18.

[0021] The collimated laser beam emitted by the total station 1 enters the laser electronic target 2 to realize the measurement of the spatial angle. The distance measuring laser emitted by the laser displacement sensor 3 measures the relative distance from the reference point to the measured point, and according to the coordinate transformation relationship of the entire system, the spatial coordinates of the measured point in the total station coordinate system are obtained.

[0022] see figure 2 , There is a circumferential V-sha...

Description

technical field [0001] The invention belongs to the technical field of space coordinate measurement, and in particular relates to a combined non-contact space coordinate measurement device. Background technique [0002] At present, the combined measurement system composed of a probe and a laser tracker or a total station instrument is widely used in space coordinate measurement due to its advantages of portability, high precision, low cost, and simple operation. The principle is to calculate the spatial coordinates of the measured point by measuring the spatial position and attitude of the probe and according to the coordinate transformation. The spatial position of the probe can be measured by a laser tracker or a total station, and the spatial attitude measurement of the probe is based on the principle of camera measurement. The system has the characteristics of high measurement accuracy and fast point touch measurement speed; however, its attitude measurement accuracy is...
