Embodiment Construction
[0055]Next, the technical solutions in the embodiments of the present invention will be described in the following examples, and the described embodiments are merely, not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.
[0056] It should be noted that all directional instructions (such as above, lower, left, right, front, and post, ...) are only used in a particular attitude (as shown in the accompanying drawings). The relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication is also changed accordingly.
[0057] Further, as described in the present invention, as described in the description of "first", "second", etc., is only used to describe purposes, and cannot be understood as an indication or implies its relative im...

The invention discloses a depth module ranging method, device, depth camera and mobile terminal. The depth module is used to measure the distance from a square object. The method includes: controlling the depth module to measure the distance of the square object. The object is photographed to obtain a depth image and a grayscale image, and the pixel positions of the depth image and the grayscale image are in one-to-one correspondence; according to the depth image, three-dimensional information on the upper surface of the square object is obtained; according to the grayscale image, obtaining the three-dimensional coordinates of the outer corner corresponding to the position of the outer corner of the square object; according to the three-dimensional coordinates of the outer corner, obtaining the effective length of the vertical side of the square object; through the three-dimensional information and the vertical The effective length of a side is measured to obtain the volume of the square object. The invention can effectively measure the volume of the square object and ensure accurate measurement of the contact position between the square object and the ground.
Description
Technical field [0001] The present invention relates to the field of depth ranging technology, and more particularly to depth modules ranging methods, devices, depth cameras, and mobile terminals. Background technique [0002] The depth module is also known as the TOF (Time of Flight, the flight time ranging) module, the depth module is a transmitted optical signal, and receives the reflected optical signal, and the measuring component of the object distance is calculated. [0003] The depth module provides a lot of convenience on people's daily lives in measurement, in which the depth module has a unique advantage in three-dimensional modeling. The volume of the square object can be quickly calculated by shooting measurements in three-dimensional modeling. The module is a reflection phenomenon in the contact position of the object and the surface of the square object and the ground by receiving light reflection, in the contact position of the square object and the ground, and th...
