Embodiment

[0092] Step 1. Install and calibrate the scanning instrument.

[0093] When the machine moves in a large range or the scanning accuracy is inaccurate, the scanner can be calibrated. Open the software, use the "Automatic" menu - "Turn an Angle" function to turn the lens and projection to a position 90 degrees away from the white fixed point mark, put the calibration plate, and click the "Settings" menu in the software - "Take a calibration map". Click Calibration Calculation, click Calculate RT. Check that the number of points is within a reasonable range (400-441). If it is not within a reasonable range, it is necessary to check whether there is interference from reflective objects around, whether the calibration board is placed correctly, whether the angle is correct, etc., and re-calibrate after adjustment. After confirming that it is correct, exit the software and reopen it to make the calibration result take effect. Then perform axis calibration, click the "Automatic" m...

Abstract

The invention provides a conformal insole generation method based on a rotary 3D foot type scanner, and relates to the technical field of conformal insole generation, and the method comprises the steps: a tested person steps on plaster with a naked foot, a rotary scanning camera carries out multi-angle multi-line structured light data collection on the instep of the tested person, and instep and base data is obtained; moving the bare foot from the plaster by the testee, and performing multi-angle multi-line structured light data acquisition on the plaster by a rotary scanning camera to obtain sole and base data; converting the instep and base data and the sole and base data into point cloud data, and respectively merging the point cloud data to generate complete instep and base point cloud data and complete sole and base point cloud data; extracting instep point cloud data and sole point cloud data, and merging to obtain complete foot model point cloud data; and generating a Mesh model according to the foot model point cloud data, and calculating a conformal insole model based on the Mesh model. According to the invention, the complete data of the foot shape of the tested person is collected, and the conformal insole is calculated and generated according to the foot shape data.

Description

technical field [0001] The invention relates to the technical field of conformal insole generation, in particular to a method for generating conformal insole based on a rotary 3D foot scanner. Background technique [0002] The comfort of foot movement is closely related to the distribution of plantar pressure. A comfortable insole needs to be designed with a reasonable pressure distribution according to the characteristics of the human foot. The existing insole production methods are mainly based on the classification of human foot shape information, and produce insoles with representative foot shapes of various groups, which have limited adaptability to individual plantar information. In specific fields, such as improving athletes' sports performance, it is necessary to design suitable insoles according to each individual to meet the requirements of sports mechanics and comfort to the greatest extent. Sports insoles that are not individually targeted cannot meet such requir...
