This paper introduces the technical methods and work flow of the geomatics products production by using non-metric digital aerial photographic imagery on digital photogrammetric workstation,studies the key technical procedures.

This paper introduces the method and workflow of aerial triangulation using non-metric digital images in Intergraph SSK system direct via operational production application,and analyzes the accuracy.

But it is non-metric digital camera,so we cannot process the digital image using traditional pho-togrammetric method.

Research on non-contact measurement methods for the dimension of inner diameter based on the principle of optical triangulation;

On the basis of electric eddy current's characteristic that non-contact measurement,we measure boring cutter's radial move accurately with two-point method,to improve the machining precision.

This instrument can realize a quick and non-contact measurement with high accuracy.

The control system based on the model can realize the induration temperature control in shaft furnace by the indirectly measurement.

In this paper, a non contact measurement apparatus by means of matrix CCD as the photoelectric sensor for the geometrical sizes of common cylindrical exterior thread is developed.

Based on the contact type measuring machine for bent tube, the probe, which is improved by using laser and CCD, can be used to achieve the non contact measurement of a bent tube.

Referring to the contact type bent tube measuring machine, a probe, which is improved by the use of two laser diodes and two photodiodes, is used to achieve the non contact measurement of the bent tube.
