摘要：In the NI Vision Builder for Automated Inspection handled using image
processing computer, image-forming module includes imaging sensor and pretreatmentcircuit, such as is calculated for executing background subtracting and/or gradient. Thealso compressible image information of the pretreatment circuit. Host computer receivespreprocessing image data, executes and is used to complete every other calculatingnecessary to machine vision applications, such as one or more wheel alignment
parameters to determine main body vehicle. In the open example for aligner wheel, whichfurther includes illumination component, which provides relevant camera control.Background subtracting, gradient calculate and relevant compression needs simpler,more cheap circuit ratio to be used for typical image pre-processing boards. However,the processing load machine vision implementation that the pretreatment at image-forming module greatly reduces host computer is compared, master computer is floweddirectly to using image data.
