Abstract of disclosure A method for three dimensional measurement of objects (1) being conveyed through or moved relative to a measurement frame (4) for, by incremental measurements of height, width and length of the object to calculate cubical and circumscribed volume of the object. Each transmitter/receiver element pair of the measure- ment frame (4) is calibrated by controlling the amount of the light emitted from the transmitter and the threshold level of the receiver, such that the signal/noise ratio of the receiver lies above a specific limit, simultaneously with the illumination time being kept the shortest possible. By incremental measurements at least one pair consisting of transmitter element and directly opposite receiver element in the measurement frame (4) is activated at time, and an external signal being a function of the movement of the object relative to the measurement frame is compared with the registered signals from the receiver elements for calculation of the said volumes. The measurement frame is constructed in the form of horizontal and vertical transmitter- and receiver modules (6.1,6.2; 8.1, 8.2; 7.1, 7.2; 9.1,9.2) ting of said transmitter elements and receiver elements, respec- tively. A computer is connected to the measurement frame for calibration of the respective transmitter- and receiver elements of the measurement frame (4) and for calculation of said volumes being derived as a result of shadow images of the object on the receiver elements. A display (22) is associated with the computer for display of the volume magnitude of the object. Utilization for e.g. calculation of freight charges of objects. (Fig. 1).
