Embodiment Construction

[0051] The following examples are used to describe the implementation of the present invention in detail, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0052] image 3 Demonstrated a package volume measurement method based on a TOF depth camera, S1: Calibration of relevant parameters, using the camera to capture the height value h of the conveyor belt 0 ; Determine the ratio K between the observed volume and the actual volume, and intermittently place several regular objects on the conveyor belt moving at a constant speed. After image processing, determine its outline, such as Figure 4 Shown and the center of mass, record the number of times the center of mass is in the statistical area, and take the average as K; S2: Obtain the depth image returned by the TOF depth camera, install the TOF depth camera above the conveyor belt, and the shooting direction ...

Abstract

The invention provides a TOF depth camera-based parcel volume measurement method. The TOF depth camera-based parcel volume measurement method comprises the steps of 1, calibrating a relevant parameter; 2, acquiring a depth image returned by a TOF depth camera; 3, extracting a hot point region, sieving and correcting data of the hot point region, and reserving a rectangular hot point region; 4, processing noise; and 5, measuring volume. By the TOF depth camera-based parcel volume measurement method, the problem volume calculation of stacked parcels on a conveying belt and volume calculation ofan irregularly-shaped parcel can be effectively solved, and the method is accurate and effective and is high in practicability.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a package volume measurement method based on a TOF depth camera. Background technique [0002] China's express delivery industry has grown by more than 50% every year for six consecutive years, and China has become the world's largest express delivery country. China accounts for 30 billion of the approximately 70 billion annual express deliveries globally. [0003] In traditional logistics sorting centers such as post offices, the sorting volume is large, there are many kinds of parcels, irregular shaped parcels appear during the loading process, densely stacked and even crowded parcels are common problems, the volume calculation under the above problems is an industry A big problem. [0004] With the continuous development of computer vision technology, it is possible to use computers or special hardware devices to measure the volume of objects. This technology has developed...
