摘要： A scanner obtains point-cloud data of adjoining parts of a product. A computing device reads two point-clouds from the point-cloud data, fits two or more lines according to the two point-clouds, selects two lines that have the same ascending direction from the two or more lines, and creates a two-dimensional coordinates system base on the two selected lines. The computing device determines a highest point in each of the two point-clouds based on distances from each point in either of the point-clouds to a corresponding selected line, and determines two nearest points in the two point-clouds. A difference between Y coordinates of the two highest points is determined as a gap-height of two adjoining parts of the product, and a difference between X coordinates of the two nearest points is determined as a gap-width between two adjoining parts.

摘要： In a method of a computing device for calibrating light channels, one or more channel options of an illumination selecting unit of the computing device are selected to turn on the one or more light channels of a light source device. A camera unit captures a first image of the light source device. A zone and a serial number of each light channel are marked on the first image. Each channel option of the illumination selecting unit is eliminated. The camera unit captures a second image of the light source device when a light channel is turned off. The first image and the second image are compared, and a correlation between the light channel that is turned off and the eliminated channel option is determined. The serial numbers of the channel options are modified and remapped according to correlations between each light channel and each channel option.
