Recuperação da topografia de ovos por meio da técnica de moiré e calibração independente

Abstract: RESUMO:A recuperação da topografia de ovos por meio de análise de imagens digitais permite, de forma não destrutiva, a estimativa das massas da gema, da clara, da casca e totais, que são produtos amplamente utilizados na esfera industrial. O presente trabalho buscou desenvolver uma metodologia para a recuperação da forma tridimensional de ovos por meio de análise de imagens, em especial usando a técnica de moiré. Foram utilizados ovos de diferentes tamanhos, classificados em: XL (mais de 73 g), L (63 a 73 g), … Show more

“…The minimum, average and maximum percentage errors found for the fuzzy model were 0.17%, 2.33% and 5.68%, respectively. The average error found was lower than the one found for the other technique used by Silva et al (2011), recovering the three-dimensional shape of eggs, which found errors ranging from 2.60% to 5.47%.…”

“…Os ovos brancos e vermelhos apresentaram valores médios de largura e comprimento estatisticamente iguais (p>0,05; Scott-Knott). Silva et al (2011), ao estudarem recuperação da topografia de ovos por meio da técnica de Moiré, verificaram que os valores médios do comprimento e largura dos ovos foram aproximadamente 57,0 e 45,2 mm, respectivamente. Silva (2014), averiguando o volume médio dos ovos de galinhas pelo método de imersão em água, encontrou o valor médio de 50,5 cm 3 , para os ovos do tipo grande.…”

“…This technique is notable for being a non-invasive and non-destructive method, being an alternative for soil profile studies, such as agricultural machine traffic, which can cause overloading of the soil and possible damage to the development of crops (Lino and Dal Fabbro, 2004) and (Mckenzie, 2015). This interferometric technique can be seen in applications such as the estimation of the surface area of broilers (Silva, 2007), in the measurementof the volume of macaúba fruit (Costa et al, 2016), in topography of eggs, estimating the mass of the yolk, white, bark and all the egg (Silva et al, 2011) and also in the investigations of surface profile in mechanical prototypes, seeking low costs and flexibility (Gomes et al, 2009), besides the postural analysis of humans (Fernandes et al, 2003).…”
