Method for determining biometric properties of pigs, comprising the determination of the weight of pigs, wherein - at least one image of the pig is created using a camera system, - wherein the images are taken from any desired recording positions around and above the pig, - wherein image processing methods, preferably pattern recognition, are used to determine distinctive points (M1SA, M20AR,... M35xKM) of the body surface, - wherein parameters of a statistical model of the pig are also created from the distinctive points (M1SA, M20AR,... M35xKM) of the surface, and - wherein the biometric properties of the pig are determined using the statistical model, characterized in that, when determining the weight of pigs from the distinctive points (M1SA, M20AR,... M35xKM) of the surface, - geodesic and/or Euclidean length dimensions such as the shoulder-ear length, the tail-shoulder length, - geodesic and/or Euclidean width dimensions such as the shoulder, chest and flank width, and - geodesic and/or Euclidean areas on the surface of the animal body, and - shape properties of defined sites of the body such as the rear region, in an elliptical, concave, etc. form, and - the contour of the body, and - circumference dimensions such as the chest circumference and the flank circumference are determined, and - in that these dimensions are provided as parameters of a weight model of the pig. - at least one image of the pig is created using a camera system, - wherein the images are taken from any desired recording positions around and above the pig, - wherein image processing methods, preferably pattern recognition, are used to determine distinctive points (M1SA, M20AR,...
