Component quality checking device based on line laser three-dimensional measurement and detection method of device

The invention provides a component quality checking device based on line laser three-dimensional measurement and detection method of the device. The quality checking device includes a mobile platform mounted on a guide rail and capable of sliding along the guide rail at a uniform speed. To-be-checked components are fixed on the mobile platform. A camera and a plurality of laser emitters are mounted above the guide rail through a mount. The camera collects images which are casted to the surfaces of the to-be-checked components by the laser emitters and deformed due to surface modulation. The camera transmits the collected image data to a computer for analysis and treatment. According to the detection method, by casting linear stripes emitted by the laser emitters to the surface of the to-be-checked components for linear scanning and by utilizing the camera for collecting image information on the to-be-checked components continuously, measured three-dimensional point cloud data and initially designed three-dimensional image are compared and analyzed in the same coordinate system for judging whether the maximum error is within the maximum permissible error range or not and screening out qualified components. The device provided by the invention is high in detection precision and realizes automatic and flow line production.

InactiveCN106600680AGuaranteed strict fitImprove work efficiency3D modellingPoint cloudAlgorithm
The invention, which belongs to the technical field of model construction, discloses a batch type refined three-dimensional modeling method of a building frame model. The method comprises the following steps: determining a range frame of a batch type refined modeling region of a building; constructing a three-dimensional model; establishing a frame model index; and constructing a model of a batch type refined modeling accessory structure. According to the method, a BSP building model reconstruction method under a DLG building outer contour constraint is put forward; and with the high-plane precision of a DLG, a defect of low precision of a point cloud boundary is overcome, so that strict matching of the main contour of the frame model with the outer contour of the DLG can be realized. On the basis of a one-to-one correspondence relationship among a building DLG base map, a building point type in a range, and a generated model, batch type refined modeling and quality checking of buildings in a large area can be realized and a well-developed production and quality checking working flow can be formed. A model space matching and duplicating method is put forward and base elevation and precise orientation information of the model can be obtained automatically, so that the precise modeling efficiency can be improved.

Multicomponent gas concentration quantitative analysis method based on absorption spectrogram reconstruction

The invention discloses a multicomponent gas concentration quantitative analysis method based on absorption spectrogram reconstruction, which comprises the following steps: preestimating the concentration of each component in analyzed gas and converting absorbance, and reconstructing the spectrogram according to a Lambert-Beer theorem; then constructing a hook-shaped loss function by taking the difference of the spectral lines of the reconstructed spectrogram and an actual spectrogram. Input takes zero as a boundary; when the input is less than zero, a function value decreases progressively, and the decrease amplitude is smaller; when the input is greater than zero, the function value increases progressively, and the increase amplitude is bigger. Then iteration operation is carried out on the concentration of each component in the gas to be analyzed by adopting a momentum method or a genetic algorithm until the concentration difference of each component in the iteration results of two adjacent times is less than a preset admissible value to end the iteration operation. The method has high analysis speed, accurate result and small influence of interference on an analysis result, can be used for gas logging, product quality check and fault diagnosis and the multicomponent gas quantitative analysis of the fields of hardware, chemical industry, environmental protection and the like.
