This study aimed to verify if biophotogrammetry can be used to determine the angles of the locomotor system of horses and thus demonstrate a complementary method for analysis of the quarters of horses. Experimental design was completely randomized with 22 horses in four treatments and the control group: treatment 1 – distance of 1.50 m and height of 0.75 m; treatment 2 - distance of 1.50 m and height equal to half of the withers height; treatment 3 - distance twice the withers height and height of 0.75 m; treatment 4 - distance twice the withers height and height equal to half of the withers height, and the control group that was the visual measurements of the joint angles on the animal. For determination of the angles, the points corresponding to the joints were spotted with adhesive and measured with using horse measuring stick and protractors and, later, five photos for each treatment were taken with a digital camera. In order to standardize, the left size of the lateral plane of the animal at rest, in standing position was used. The images with 4000 x 3000 pixels of resolution were subsequently edited in CorelDraw® program for angles determination. Data was submitted to analysis of variance to determine the possibility of utilization of the images and then to the correlation tests of Spearman and Kappa to determine which camera position would be the most adequate for each angle considering the camera positions evaluated in this study. There was no significant difference in the analysis of variance (p>0.05), determining that the images can be used to evaluate joint angles of horses. Correlation tests determined that the best positions of camera were T4 (distance twice the withers height and height equal to the half of the withers height) and T2 (distance at 1.50 m and height equal to the half of the withers height). This study concluded that the position of the camera must respect the conformation of the animals in order to obtain reliable images for evaluation of the joint angles. |
