Embodiment approach
[0036] According to one embodiment, the image acquisition device is a CCD camera, and the image processing device is an industrial computer. The pixels of the CCD camera are high enough (for example: 10 million pixels) so that the sampled pictures can clearly distinguish the scale and numerical information on the scale. The industrial computer is mainly used to receive the pictures sampled by the CCD camera, perform image recognition, and calculate the height of the material.
[0037] Preferably, the floor of the warehouse is a horizontal plane. The reason that the floor of the warehouse is a horizontal plane is to facilitate the setting of scales, as well as later image recognition and calculation of material height. In some material storage bins, the height of the material can also be calculated if the bin floor is not horizontal, for example, where the bin floor is conical and the top of the cone faces downwards.
[0038] Preferably, the surface of the wall is a plane or ...

The embodiment of the invention provides a material height measuring device and a material height measuring method. The measuring device is used for measuring the stacking height of materials in a warehouse. The measuring device comprises a scale arranged on the ground of the warehouse, scales arranged on the surfaces of two opposite wall bodies in the warehouse and image acquisition devices arranged on the surfaces of two opposite wall bodies in the warehouse. The photographing range of each image acquisition device can cover all scale and numerical value information of the scale on the ground of the warehouse when no materials are stacked in the warehouse and all scale and numerical value information of the scale on the surface of the wall body below the corresponding image acquisition device. The image acquisition device is used for photographing and sampling the inner part of the warehouse with the materials stacked, and the sampled image information is sent to an image processingdevice. The device and the method can measure the mateirla height in the warehouse in real time, and the material transportation management efficiency is improved.
Description
technical field [0001] The invention relates to the field of measurement, in particular to a material height measuring device and a material height measuring method. Background technique [0002] During the production process, the height of the material pile is in a state of dynamic change. Under normal circumstances, the measurement and dynamic management of the height of these materials needs to be measured and estimated manually, which is inefficient, and the transportation of the feeder must be stopped at regular intervals, which affects the continuity of production. Therefore, in order to realize the automatic management of the material yard, it is first necessary to realize the digital technology of the material yard, and the key point of the digital technology of the material yard is how to realize the automatic measurement and dynamic observation of the height of the material pile. Therefore, the automatic detection of the height of the material pile is an important...
