The invention provides an object measuring method. The object measuring method includes the steps that an color image and depth data of a to-be-measured object are obtained; the depth data is subjected to conversion processing, and a depth image is obtained; the to-be-measured object in the color image is identified, and a color datum point corresponding to the to-be-measured object in the color image is obtained; the color datum point is processed, and a depth datum point corresponding to the to-be-measured object in the depth image is obtained; the depth image is subjected to conversion processing, the to-be-measured object in the depth image after conversion processing is identified, and depth information of the to-be-measured object is obtained; a depth frame corresponding to the depthdatum point is established; depth information contained in the depth frame corresponding to the depth datum point is counted, and average depth information of the counted depth information is computed, and serves as depth information of the color datum point corresponding to the depth datum point in the color image; based on the depth information of the color datum point and the computed height of the to-be-measured object, the volume of the to-be-measured object is determined.
Description
technical field [0001] The present application relates to the technical field of image processing, in particular, to an object measurement method and device. Background technique [0002] In the logistics industry, the volume information of the package is important logistics information, and the reported volume information is of great significance to the estimation of logistics costs and the construction of warehouses. The current volume measurement system includes grating-based measurement and computer vision-based measurement. The cost of grating-based measurement is high, and the accuracy is also limited by the grating. The cost of vision-based measurement is low. However, vision-based measurement mainly includes binocular measurement and structured light. Measurement and Time of Flight (ToF) measurement. [0003] The solution based on binocular vision (including active binocular) measurement can achieve very high resolution, but when the measured object is far away from...
