Abstract

The invention provides a speed measurement method, device and equipment and a computer readable storage medium. The method comprises the following steps: enabling first image collection equipment to collect a first image, and enabling second image collection equipment to collect a second image, wherein the first image and the second image have the same partial image; calculating the movement displacement of a movable carrier according to the spacing distance between the first image collection equipment and the second image collection equipment and the relative displacement of the same part ofimages of the first image and the second image; obtaining the interval time of the acquired images of the first image collection equipment and the second image collection equipment; and determining the moving speed of the movable carrier according to the moving displacement of the movable carrier and the interval time of the acquired images. According to the scheme, the problems of low vehicle displacement / speed measurement precision and high cost in the prior art are solved, the vehicle displacement / speed measurement cost is reduced, and the accuracy of the measurement result is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a speed measurement method, device, equipment and computer-readable storage medium. Background technique [0002] The measurement of vehicle displacement / velocity is a basic measurement item in the transportation industry and the automotive industry. Such as vehicle speed measurement, overspeed measurement, acceleration measurement, etc. all rely on this basic measurement item. High-precision vehicle displacement / velocity measurement can be used to evaluate vehicle performance, road conditions, etc., and is of great significance to the formulation of traffic rules and identification of traffic accidents. [0003] Existing vehicle displacement / speed measurement technologies mainly include GPS speed measurement, radar speed measurement, photoelectric or electromagnetic induction speed measurement, optical speed measurement, etc. GPS speed measurement, specifically...
