Embodiment 1

[0045] Use "light sensor-based 3D data acquisition equipment" including but not limited to RGBD cameras, lidars, light curtains, etc. to collect raw data, and then complete samples through 3D reconstruction algorithms including but not limited to Kintinuous, ElasticFusion, InfiniTAM, BundleFusion, Loam, etc. 3D reconstruction to obtain a preliminary 3D model of the sample.

[0046] Due to the inherent defects of "3D data acquisition equipment based on light sensors", the preliminary 3D model is usually defective in terms of data integrity, which is specifically reflected in the fact that there are often holes on multiple surfaces of the sample for which data cannot be obtained, or even a whole The absence of all data on the surface.

[0047] In addition, the spatial pose of the preliminary 3D model is arbitrary, and it needs to be restored from the arbitrary pose to the physical real pose, that is, to be straightened.

[0048] Attitude refers to the 3D rotation state of the o...

Abstract

The present invention relates to the field of visual recognition technology. It is a non-contact device for measuring the drainage volume of special-shaped objects. The reconstruction algorithm completes the three-dimensional reconstruction of the sample, and obtains the preliminary 3D model of the sample; step 20, pose calculation: detects the feature detection of the preliminary 3D model of the sample, completes the pose calculation of the preliminary 3D model of the sample, and obtains the straightened position by restoring the real physical pose of the sample 3D model of the final sample; step 30, model completion: complete the 3D model of the sample after the alignment, enough to obtain a 3D model of the sample that is aligned and complete without holes; step 40, volume calculation: through the integral volume algorithm, calculate the to-be Measure the true volume of an object. The non-contact device for measuring the drainage volume of the special-shaped object has the advantages of high volume measurement accuracy and reduced equipment cost.

Description

technical field [0001] The invention relates to the technical field of visual recognition, in particular to a non-contact device for measuring the drainage volume of special-shaped objects. Background technique [0002] Application Scenario 1: Real volume measurement of warehouse stockpiles [0003] Explanation: For warehouse managers, it is necessary to frequently check the real volume of a pile of goods in the current warehouse (that is, the drainage volume), for example: it is necessary to quickly and accurately know the real mass and real volume of the coal pile in the current warehouse, and accordingly to determine how many delivery trucks are needed. The measurement method of true volume is usually visual inspection, which is very inaccurate and depends on the experience of skilled workers. The present invention can effectively solve this problem, and measure the size of the real volume (drainage volume) quickly and very accurately. [0004] Application Scenario 2: ...
