“…Si bien ya está demostrado que el trabajo de medición animal, a poyado en tecnología de captura de imagen arroja resultados semejantes a los hechos de forma manual (Tasdemir, et al, 2008), estas técnicas determinan su éxito en los recursos y métodos empleados en el momento de tomar la imagen; aspectos como la iluminación, la posición del animal, la distancia del dispositivo, determinan la calidad de la captura (Hawkins, et al, 2001), lo cual sugiere un proceso estricto y riguroso que garantice las tomas con resultados más cercanos a la realidad.…”

Abstract:The production of native or creole breeds in all geographical areas of Colombia have in common, the search for better meat and milk production in the tropics, but to do this, cattle production has to adapt technological concepts that allows to potentiate the Maximum of the animals' quality to face the environmental conditions that will require most biological strength. The selection, evaluation and judgment should be supported in all the resources necessary to be successful. This paper shows how using agile methods, a software for zoometry that supports the process of making zootechnical decisions was built allowing improved the production in bovine cattle, becoming a technological alternative for taking animal's measure instead the photogrammetry.Keywords: Animal genetics, zoometry linear evaluation, selection, trial, appellate.Resumen: La producción de razas criollas o nativas en toda las áreas geográficas de Colombia tienen en común, la búsqueda por mejorar la producción de carne y leche en el trópico, pero para lograrlo la producción bovina tiene que adaptar conceptos tecnológicos que le permitan potencializar al máximo la calidad de los animales para enfrentarse a unas condiciones ambientales que le van a exigir su mayor fortaleza biológica. La selección, la evaluación y el juzgamiento se deben apoyar en todos los recursos necesarios para que sea exitosa. Este trabajo muestra como por medio de métodos ágiles, se construyó un software para zoometría que apoya el proceso de toma de decisiones zootécnicas, permitiendo mejorar la producción de razas bovinas, convirtiéndose en una alternativa tecnológica para la toma de medidas animales que la fotogrametría.

Digital close range photogrammetry for 3D body scanning for custom‐made garments

The Photogrammetric Record

Among several biometric applications, one of those currently attracting great interest is the possibility of carrying out 3D digitisation of human individuals to analyse their physical characteristics. These characteristics can be used for several purposes, such as security, medicine and tailoring for custom‐made clothing. In recent years, although the development of online 3D scanning systems has been accelerating fast, little work has been devoted to offline systems, which would be particularly suitable for the textile and clothing industries. In the present research the author presents a specially designed low‐cost offline 3D body digitiser, based on digital close range photogrammetry. A specially designed photogrammetric 3D scanner of the human body is presented, featuring automatic image processing procedures. The scanning system consists of eight cameras with a resolution of 5 megapixels, equipped with 16 mm wide‐angle lenses; there are four white‐light illuminators, of 100 W each. Tests on a tailor’s dummy and on whole human bodies are reported, demonstrating the usefulness of the technique for textile applications. The digitisations performed on human bodies generally yield worse results than the corresponding ones on the dummy, and full body digitisations are worse than corset digitisations owing to the lower point density and to target distortion. Nevertheless, the results are satisfactory for tailoring applications that do not require high accuracies.

This study presents a novel technique for the measurement of insertion depth of an epidural Tuohy needle in real-time. A wireless camera is used which transmits video images during insertion to a host computer. The computer contains the image processing algorithm to detect the visible needle in the image and measures the length. The measurement is done by HSV background removal, colour comparison and using RGB intensity profile to locate 10 mm markings on the Tuohy needle shaft. The visible length is then subtracted from the known length of the needle to calculate the depth of the needle tip. The camera can be placed in the operating theatre between 50 and 100 cm away from the needle insertion site. Wireless camera is beneficial since it minimises disturbance to the anaesthetist and the patient and avoids ethical and sterility concerns which would be caused by bringing additional equipment into the hospital room. The speed of the image processing technique is 10 frames per second with a maximum error of ±3 mm. The image processing failure rate was 3 frames out of 150 which gave an overall reliability of 97.8% during insertion. Also this enables continuous needle depth monitoring during insertion by storing measurements into a data file. The purpose of measuring needle depth in real time is to precisely place the needle in the epidural space.
