Embodiment
In order that the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings and specific implementation
The utility model is described in detail example.
The utility model provides a kind of scolding tin three-dimensional surface scanning means, circuit board with translation stage linear uniform motion,
When scolding tin on circuit board shoots field by video camera, the twice laser lines on scolding tin surface can form offset, when will be different
Between the offset put carry out three-dimensional data reduction, finally give scolding tin three dimensional surface data information.
Before construction measurement, a scaling board is used, the fixed thickness of this scaling board is 0.2mm, for laser rays
By having during the scolding tin surface of height, laser lines offset can be formed, this offset value and scaling board 0.2mm offset value are changed
Calculate the height for obtaining this scolding tin.
When scolding tin at the uniform velocity moves ahead with mobile platform, the laser rays that two generating lasers are projected forms two on platform
Road parallel lines, when there is scolding tin to pass through camera field of photography, twice laser rays formation offset is obtained using image processing algorithm
Laser rays centre coordinate when there is each pixel of laser line position on scolding tin surface, then obtain on platform and have in the laser of laser rays
Heart coordinate, two coordinate differences and time write file in real time, when scanning object skids off scanning area, terminate Current Scan automatically.
Embodiment 1
The present embodiment provides a kind of scolding tin three-dimensional surface scanning means, including：Generating laser I, generating laser II, thousand
Million web cameras, translation stage；Circuit board with scolding tin is placed on translation stage, generating laser I, generating laser II, thousand
Million web cameras are placed in above translation stage, and generating laser I, generating laser II are located at gigabit networking video camera both sides；Institute
