The detection area can be determined according to the placement position of the object a to be detected and the relative position relationship between the placement position and the perspective part 102.
For example, the object a to be tested has 4 foot pads, the perspective part 102 has 4 foot pads, and the 4 perspective parts 102 correspond to the four foot pads of the object a to be tested respectively; the number of detection regions is 4, and the detection regions are located within the range of the four perspective parts 102.
Or, for example, the object a to be measured has 4 foot pads, and the support part is a transparent glass support plate; the detection area has 4, respectively corresponds 4 callus on the sole of the article A that awaits measuring.
After the detection area is set, the moving range of the distance measuring sensor 103 in the measurement state is limited in the detection area, but not in the range of the perspective part, so that the moving range of the distance measuring sensor 103 is correspondingly reduced, and after the moving range is reduced, the distance measuring sensor does not need to move in a larger range to search for the position of the foot pad, thereby being beneficial to improving the detection efficiency and accuracy.

Specifically, when the bottom surface of callus on the sole contacts and forms certain angle with the upper surface of backup pad 101, the maximum distance between the bottom surface of callus on the sole and the upper surface of backup pad 101 is not 0, and the bottom surface of callus on the sole does not laminate completely with the upper surface of backup pad 101 promptly, realizes from this that the detection to the bottom surface of callus on the sole and the upper surface laminating degree of backup pad 101 does benefit to and improves product quality.

and the discharging device 109 is used for acquiring the object A to be detected after the flatness detection is finished so as to drive the object A to be detected to leave the flatness detection structure.
Automatic feeding and discharging can be realized through the detection system, so that the automation of detection can be realized, and the labor cost is reduced.
