Abstract

The invention discloses a judgment method suitable for optical flash three-dimensional imaging radar interference, and aims to solve the problem that the accuracy of distance calculation is often influenced by external strong light interference received by an optical flash three-dimensional imaging system, so that an error occurs in an imaging distance, and the false alarm rate is increased. According to the method, interference of short-time strong light incidence or long-time direct background light entering the Flash imaging radar can be judged, the distance range of a target is defined according to a distance gate gating method and a pulse rising edge and falling edge measuring method, and imaging radar and target interference pre-judgment is achieved. The method is simple and reliable, and the false alarm rate of the flash three-dimensional imaging radar can be reduced.

Description

technical field [0001] The invention belongs to the industrial field and relates to a judgment method suitable for optical flash three-dimensional imaging interference. Background technique [0002] The basic principle of optical 3D imaging technology is to collect reflected radiation from the detection scene by illuminating optical pulses. The active illumination of the optics is completely independent of day or night light environment conditions, so the image contrast is relatively robust in this respect. [0003] The advantages of optical 3D imaging technology are: (1) Optics are used as the lighting source, independent of ambient light, which can well avoid the influence of sunlight on the detection system and realize all-day work. (2) Optics have excellent directivity and extremely high power density, so the working distance of high-precision imaging systems can be expanded. (3) The 3D information of the target can be obtained directly without relying on the target fe...
