| dc.description.abstract | Este proyecto, presenta el diseño y desarrollo de una aplicación móvil funcional capaz de estimar la producción de cacao, que propone la implementación de técnicas de visión por computador y aprendizaje profundo. Esto se debe a que la detección de objetos en la agricultura es importante para estimar la producción de un cultivo, porque incrementa la certeza en la toma de decisiones por parte de un agricultor, por consiguiente, el diseño propuesto realiza un conteo de las mazorcas de cacao que se encuentran en tres estados de sanidad, ya sea con presencia de monilia, fitóftora o completamente sanas. La aplicación planteada hace uso de una cámara de un dispositivo móvil y el sistema operativo Android. Los elementos presentes en el sistema, son un modelo de aprendizaje de máquina entrenado, un conjunto de datos, y tecnologías que apoyan el proceso de desarrollo de software. En primera instancia, se realiza una revisión de la literatura para profundizar sobre las técnicas, tecnologías, y métricas asociadas con visión artificial y que puedan ser aplicadas en el proyecto. Luego, se propone la selección de un conjunto de imágenes con Theobroma cacao. Asimismo, se plantea la adaptación de un modelo de aprendizaje profundo con una definición de parámetros e hiper parámetros, para posteriormente proponer un diseño y desarrollo de un prototipo móvil que detecta, clasifica y localiza las mazorcas de cacao con sus respectivos estados de sanidad, y a su vez estima la producción en términos de kilogramos de granos de cacao seco, teniendo en cuenta la variedad indicada por el usuario. Los resultados obtenidos dejan la evaluación de 8 modelos, en donde el mejor obtiene una mAP de 80.09% y se determina la incidencia de variables asociadas al balanceo sobre la precisión. | spa |
| dc.description.abstractenglish | This project presents the design and development of a functional mobile application capable to estimate cocoa production based on the implementation of computer vision and deep learning techniques. Object detection in agriculture is important to estimate production in a crop because it increases the confidence in decision making by a farmer, therefore, the proposed design performs a count of cocoa pods that are in three sanitary states, either with the presence of monilia, phytophthora or completely healthy. The following application implements an Android mobile device camera. The elements existing in the system contain an object detection model, a dataset, and technologies that support the software development process. A literature review is done to explore techniques, technologies, and metrics associated with computer vision. Subsequently, a selection of an image dataset is done to train a deep learning model, setting up parameters and hyperparameters. Consequently, a design and development of a mobile prototype are proposed to detect, classify, and localize cocoa pods with their respective health status, and it returns the estimated value of production given in kilograms of dry cocoa beans, taking into account the variety indicated by the user. The results show the evaluation of 8 models, where the best one obtains a mAP of 80.09% and the incidence of variables associated with the balancing on the accuracy is determined. | spa |
