Embodiment 1

[0048] Embodiment 1: Taking the current collection point position as the reference point, the intelligent robot equipped with the camera moves at the speed v for t time, then the distance B=v*t that the intelligent robot moves can be calculated; then the video data collected by the camera detects Search for the target object D, if the target object D is detected, then obtain and store the second image C that currently contains the target object D, and calculate the abscissa Xc of the target object D on the second image C; If no target object D is detected, the camera continues to collect video data, and performs target detection on the collected video data.

Embodiment 2

[0049] In the second embodiment, in addition to the movement of the intelligent robot, the robot can also be kept still, and only the camera can be moved. For example, taking the current collection point position as the reference point, the camera is translated at a speed v for t time, and the distance B = v*t. Then, the target object D is detected and searched through the video data collected by the camera. If the target object D is detected, the second image C that currently contains the target object D is acquired and stored, and the horizontal direction of the target object D on the second image C is calculated at the same time. Coordinate Xc; on the contrary, if the target object D is not detected in the video data, the camera continues to collect video data, and performs target detection on the collected video data. The adoption of this solution enables the intelligent robot to smoothly collect video data including target objects in a small field without moving, thus exp...

Embodiment 3

[0051] Embodiment 3, if the collection point does not move and the target object moves in this embodiment, the motion information of the target object D needs to be obtained first, and the distance B that the collection point moves relative to the target object D is calculated through the motion information, and then the camera is used to collect the motion information. The received video data detects and searches for the target object D. If the target object D is detected, the second image C that currently contains the target object D is obtained and stored, and the abscissa Xc of the target object D on the second image C is calculated simultaneously; , if the target object D is not detected in the video data, the camera continues to collect video data, and performs target detection on the collected video data.

[0052] In step S103, the depth information of the target object is calculated through the binocular ranging principle to complete the ranging.

[0053] Preferably, t...

Abstract

The invention relates to a monocular distance measurement method and system, an electronic device and a storage medium, and the method comprises the steps: obtaining video data, carrying out the target detection of the video data, obtaining a first image containing a target object, and calculating the abscissa of the target object on the first image; thirdly, calculating the distance of relative movement between the collection point and the target object, detecting the target object through the video data, obtaining a second image containing the target object at present, and calculating the abscissa of the target object on the second image; and finally, depth information of the target object is calculated through a binocular distance measurement principle, and distance measurement is completed. By means of the method and device, the problems that the accuracy of obtaining the target object through intelligent vehicle insertion is not high, and the vehicle insertion production cost is high are solved, the cost is reduced, and the production efficiency and the grabbing accuracy are improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular, to a method, system, electronic device and storage medium for monocular ranging. Background technique [0002] With the development of the era of industrial digitalization and artificial intelligence technology, the traditionally used items are transported by trucks, and they are moving step by step towards the automatic transport of unmanned intelligent trucks. The application of intelligent car plug-in has greatly improved industrial production efficiency, but it also faces challenges. When moving objects through intelligent truck insertion, it is necessary to accurately locate the boundary position of the target through visual information to achieve the purpose of alignment and registration. Therefore, the distance measurement of the target object and the intelligent recognition of the spatial boundary position are the necessary prerequisites for t...
