An apparatus and method for determining the volume, form and weight of fish or other objects is presented. A linescan camera records a top view of an object and at the same time records a profile view of the object reflected by a mirror located adjacent to the object. The mirror is positioned to reflect a view of the object which is perpendicular to the direct view of the camera and to the direction of motion of a conveyor belt along which the object moves. As the object moves along a conveyor belt through the field of view of the camera, a number of cross-sectional images are recorded and transmitted to a microprocessor. The microprocessor determines the maximum width of each cross-section from the direct image and the maximum thickness from each cross-section reflected image. Based upon the width and height of each cross-section and a form factor and estimated object density, the microprocessor calculates volume ane weight for each cross-section and adds the series of object cross-sections together to determine a volume and weight of the object.
