Embodiment 1

[0032] This embodiment discloses a monocular camera ranging method based on target position information.

[0033] like figure 1 As shown, the monocular camera ranging method based on target position information includes the following steps:

[0034] S1: Obtain an image to be tested containing the target to be tested through a monocular camera;

[0035] S2: perform target detection on the image to be measured, and obtain the position information of the target to be measured in the image to be measured;

[0036] S3: Based on the position information of the target to be measured in the image to be measured, combined with the following ranging model, the corresponding longitudinal distance of the target is calculated as the distance between the target to be measured and the monocular camera;

[0037] Ranging model:

[0038] In the formula: D represents the target longitudinal distance; k represents the set fitting parameters; y 1 and y 2 Indicates the position information o...

Embodiment 2

[0079] This embodiment discloses a readable storage medium.

[0080] A readable storage medium on which a computer management class program is stored, and when the computer management class program is executed by a processor, implements the steps of the method for measuring the distance of a monocular camera based on target position information of the present invention. The readable storage medium may be a device with a readable storage function such as a USB flash drive or a computer.

Abstract

The invention relates to the technical field of monocular camera distance measurement, in particular to a monocular camera distance measurement method based on target position information and a readable storage medium. The method comprises the following steps: acquiring a to-be-detected image containing a to-be-detected target through a monocular camera; performing target detection on the to-be-detected image to obtain position information of a to-be-detected target in the to-be-detected image; and based on the position information of the to-be-measured target in the to-be-measured image, calculating a corresponding target longitudinal distance as the distance between the to-be-measured target and the monocular camera in combination with the following distance measurement model. The invention further discloses a readable storage medium. According to the invention, the distance measurement of the aerial target can be realized, so that the comprehensiveness and effectiveness of monocular camera distance measurement can be improved.

Description

technical field [0001] The invention relates to the technical field of monocular camera ranging, in particular to a monocular camera ranging method based on target position information and a readable storage medium. Background technique [0002] At present, vehicles with Advanced Driver Assistance System (ADAS) or Autonomous Driving (AD) functions have been gradually introduced to the market, which has greatly promoted the development of intelligent transportation. The sensors that support AD / ADAS mainly include radar, visual camera system, lidar, ultrasonic sensor, etc. Among them, the visual camera system is the most widely used because it can obtain the same two-dimensional image information as human vision, and its typical applications include lane detection, Object detection, vehicle detection, pedestrian detection, cyclist detection and other specified target detection. [0003] The visual camera system mainly includes monocular camera and stereo camera. Among them, ...
