Volume measuring method and depth camera module group

Abstract

The invention discloses a volume measuring method and a depth camera module group. The volume measuring method comprises the following steps of obtaining standard point cloud data of a first depth camera and a second depth camera installed in a cargo box body, and according to a depth image shot by the first depth camera under a preset standard posture, acquiring cargo placement information in thecargo box body; and acquiring a volume of a cargo in the cargo box body based on the cargo placement information and a spatial position of the standard point cloud data. In the invention, through obtaining the cargo placement information in the cargo box body, volume measurement calculation is performed based on a cargo placement condition, a condition of erroneously calculating a non-cargo volume within the cargo volume is avoided, an error is reduced, volume measuring result accuracy is increased and a measuring process is stable.

Description

technical field [0001] The invention relates to the technical field of depth cameras, in particular to a volume measurement method and a depth camera module. Background technique [0002] With the development of the logistics industry, the freight business has received more and more attention. How to digitally control the loading rate of trucks and the volume of on-board cargo is an inevitable requirement for digital management of the logistics industry and improvement of efficiency. With the maturity of the depth camera technology, the depth camera has developed rapidly and has received extensive attention. Using the depth camera, a non-contact visual sensor, to measure the volume of goods and serve the logistics and transportation industry has become the focus of research. [0003] There is a volume measurement scheme, which is to use the depth camera to obtain the three-dimensional point cloud of the cargo surface in the cargo box, and then perform triangulation to calcul...

Problems solved by technology

[0003] There is a volume measurement scheme, which is to use the depth camera to obtain the three-dimensional point cloud of the cargo surface in the cargo box, and then perform triangulation to calculate the volume of the cargo after projecting the three-dimensional point cloud on the cargo surface. This scheme reduces the measurement error to a certain extent , but when the goods are randomly placed in the container, the goods are easy to be blocked and cause visual blind spots, which leads to inaccurate volume measurement of the goods
