Body measurement of riding horses with a versatile tablet-type 3D scanning device.

Abstract: The measurement of various body dimensions of horses plays a significant role in quality improvement, genetic breeding, health, and soundness. There has been significant advancement in the technology for acquiring stereoscopic images with a three-dimensional (3D) scanner. This study aimed to validate the accuracy of body measurements obtained from stereoscopic images taken with a 3D scanner. We manually took the following body measurements for 8 riding horses: height at the withers, height at the back, height at the croup, chest depth, width of the chest, width of the croup, width of the waist, girth circumference, cannon circumference, and body length. Using a versatile tablet-type 3D scanning device, we captured a 3D image of each horse. Relative errors varied from -1.37% to 6.25%. The correlation coefficient between manual and 3D measurements was significant for all body measurements (P<0.01) except for width of the waist and cannon circumference. The low accuracy of cannon circumference (r=0.248) was due to effect of hair. A simple regression analysis of all body measurements revealed a strong correlation (P<0.001, R=0.9994, root-mean-square error [RMSE]=1.522). Notable advantages of this methodology include high accuracy, good operability, non-contact, high versatility, and low cost. Further studies are required for the establishment of an accurate measurement methodology that can scan the whole body in a shorter time.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research aimed to validate the accuracy of body measurements of riding horses, obtained from stereoscopic images taken with a 3D scanner. The findings reveal that the vast majority of measurements closely matched those obtained through manual measurement.

Objective of the Paper

  • The objective of the study was to examine the accuracy of body measurements taken from stereoscopic images of horses captured with a 3D scanner. The researchers sought to validate this modern technique against traditional manual measurements.

Methodology

  • The team manually measured various body dimensions of eight riding horses, which included aspects such as height at the withers, chest depth, girth circumference, and body length.
  • After recording these measurements, they obtained a 3D image of each horse using a tablet-type 3D scanning device.
  • These images were then used to gather similar body measurements that had been taken manually.

Findings

  • There was a significant correlation between the 3D measurements and the manual measurements for all body dimensions, barring the width of the waist and cannon circumference.
  • The research notes that the lack of accuracy in measuring the cannon circumference was likely due to the effect of the horse’s hair.
  • A relative error range of -1.37% to 6.25% was noted between the 3D and manual measurements.
  • The low error rate, high correlation coefficient, and a minimal root-mean-square error (RMSE) suggest high accuracy in the 3D scanning method.

Benefits and Further Research

  • The measuring methodology with 3D scanning was discerned to have several significant advantages including its non-contact nature, low cost, high versatility, good operability, and high accuracy.
  • However, the paper concludes with a recommendation for further research into developing an even more accurate measurement methodology, capable of scanning the horse’s complete body in less time.
