Abstract

The invention discloses an active light hand-held target and a cooperation mark point identification method thereof. The active light hand-held target comprises a target main body, a wireless switch controller, a handle, a light modifying plate, a diffuser plate, a light source aluminium substrate, and a measuring head. The wireless switch controller is disposed above the handle. The light modifying plate is disposed inside the light modifying plate groove of the target main body. The diffuser plate is fixedly adhered to the surface of the light modifying plate. The light source aluminium substrate is fixed on the back of the target main body. The handle is disposed on the back of the light source aluminium substrate. The measuring head is fixed at the tail of the target main body. The light modifying plate is equipped with a plurality of light-transmitting circular holes that are taken as cooperation mark points, an active light source is disposed on the light source aluminium substrate to correspond to each cooperation mark point, and the diffuser plate is provided with light equalizing films that correspond to the cooperation mark points. The active light hand-held target is convenient to use, is wide in viewing angle and usage scope, and is also high in detection precision.

Description

technical field [0001] The invention belongs to the technical field of optical three-coordinate measurement, and in particular relates to an active light hand-held target used in the optical three-coordinate measurement technology and a method for recognizing cooperative mark points thereof. Background technique [0002] The manufacturing industry is one of the pillar industries for the development of the national economy, and measurement technologies such as spatial positioning and dimension measurement are necessary conditions for the development of the machinery manufacturing industry. With the development of aerospace, shipbuilding, metallurgy, automobile manufacturing, port machinery, and wind power equipment, the trend of heavy-duty and integrated equipment is becoming more and more obvious. In the manufacturing and assembly process of large-scale equipment, how to realize the precision measurement of the geometric dimensions and spatial positions of large-scale workpi...
