Problems solved by technology

The traditional positioning methods relying on wireless signals, such as radio frequency signal positioning, wireless network positioning, etc., are large or small because the metal material of the car body affects the signal transmission, so the positioning accuracy cannot meet expectations, and the depth sensor will not be affected by this, so it will be The positioning of the vehicle by the depth sensor is a faster and more convenient application
[0004] Defects of the existing technology: the RGB camera cannot recognize the distance and attitude of the vehicle / personnel, and the wireless signal positioning is easily affected by the metal material of the body

Embodiment 1

[0053] Embodiment one: if figure 1 As shown, a positioning method based on depth recognition in the garage:

[0054] In the first step, M depth sensors 1 are set in the garage, and the depth data detection area of ​​the M depth sensors 1 covers the driveway and each parking space of the garage;

[0055] In the second step, when the vehicle / person enters the garage, the N depth sensors 1 closest to the vehicle / person detect the depth data of the vehicle / person, M≥N;

[0056] In the third step, the garage server calculates the position of the vehicle / person in the garage by combining the N depth data.

[0057] The depth data in this embodiment is a depth image of a vehicle / personnel, and the depth data detection area of ​​each of the depth sensors 1 is a fixed area, then N takes the minimum value.

[0058] N is preferably 1, and the third step is as figure 2 Shown:

[0059] A1, the garage server establishes a garage positioning map, and the garage positioning map includes t...

Embodiment 2

[0063] Embodiment two, such as image 3 As shown, a positioning method based on depth recognition in the garage:

[0064] In the first step, M depth sensors 1 are set in the garage, and the depth data detection area of ​​the M depth sensors 1 covers the driveway and each parking space of the garage;

[0065] In the second step, after the vehicle / personnel enters the garage, after the depth reading activation device reads that the vehicle / personnel enters the garage, the depth sensor within the reading range of the depth reading activation device starts to work;

[0066] In the third step, when the vehicle / person enters the garage, the N depth sensors 1 closest to the vehicle / person detect the depth data of the vehicle / person, M≥N;

[0067] In the fourth step, the garage server calculates the position of the vehicle / person in the garage by combining N pieces of depth data.

[0068] The depth data described in this embodiment is the depth distance of the vehicle / personnel, and...

Abstract

The invention discloses a method and system for positioning in a garage based on depth recognition. The method comprises the following steps: setting M depth sensors in a garage; detecting depth dataof the vehicle/person by the N depth sensors closest to the vehicle/person after a vehicle/person enters the garage, wherein M is greater than or equal to N; and calculating the location of the vehicle/person in the garage through a garage server by combining N depth data. The system comprises a garage server, wherein M depth sensors and L depth reading activation devices are arranged in the garage, and the depth data detection area receiving regions of the M depth sensors cover the lanes and each parking space of the garage. The method and system for positioning in a garage based on depth recognition has the beneficial effects that: identities and locations of vehicles/persons entering the garage can be quickly recognized to provide multiple services for vehicles/persons, such as parkingguidance and road guidance; depth identification can be used to quickly determine the identities and locations of the vehicles/persons; and the deep reading activation devices are set to save the workload of the depth sensors.

Description

technical field [0001] The invention relates to the technical field of garage positioning, in particular to a depth recognition-based positioning method and a positioning system in a garage. Background technique [0002] The depth sensor is a device that integrates an RGB camera and a 3D data detection mechanism. Since the depth sensor can detect the depth data of each element in the plane image and the scene in real time, a 3D scene map can be obtained through joint operation, and its accuracy is the same as the obtained 3D The image is better than the data obtained by pure RGB camera, so it is widely used in human body recognition, face recognition and other fields, such as somatosensory games, faceID, etc., but the existing depth sensors are more limited in the field of pan-entertainment, There are still few applications in more life-like fields, and its market potential has not yet been tapped. [0003] As a highly used life scene in the garage, the identity of the ente...
