摘要： The present disclosure refers to a method for determining a bulk material such as fertilizer, seed or the like, the method comprising: providing a bulk material (2) to be distributed such as fertilizer, seed or the like by a distribution machine; providing a measurement tool (1) having an optical landmark (7) on a front side of the measurement tool (1); providing the measurement tool (1) in a measurement position in which the bulk material (2) is provided in proximity to the measurement tool (1); providing a camera device (3) configured to detect images; detecting image data by the camera device (3), the image data indicative of an image of the front side of the measurement tool (1) provided in the measurement position and the bulk material (2) provided in proximity to the measurement tool (1); and determining characteristics of the bulk material (2) from image data analysis of the image data. In the one or more processors, the determining comprises: determining the optical landmark (7) from the image data; in response to determining the optical landmark (7), providing dimensional data assigned to and indicative of dimensional characteristics of the optical landmark (7); and determining characteristics of the bulk material (2) taking into account the dimensional characteristics. Further, a measurement system for determining a bulk material is provided. (Fig. 1)
