Problems solved by technology

[0002] The existing common target recognition technology for civilian vehicles and ships generally uses radar systems. When this system identifies small targets, such as targets below 0.25 square meters, it is easy to make mistakes in judgment, and the cost is as high as tens of thousands of yuan.
There is also an ultrasonic recognition system, which has very low anti-interference performance and poor effect
Therefore, the above two systems have not been widely used in civilian vehicles and ships, especially in vehicles.
However, without early warning devices, accidents are prone to occur during the travel of vehicles and ships, and there are potential safety hazards.

Embodiment Construction

[0009] The present invention will be further described below in conjunction with embodiment:

[0010] The present invention is: the light emitted by the light source is irradiated to the monitoring surface in front of it through the grating or light spot, and the monitoring surface reflects the light to the receiving device, and the receiving device transmits the received signal to the signal processing system for processing, and the signal processing system Quickly identify whether there is a target on the monitoring surface according to the difference of the received signal, so as to provide useful control signals. When there is no target on the monitoring surface, the light emitted by the light source passes through the grating or light spot, and the light signal reflected from the monitoring surface to the receiving device contains the image of the grating or light spot, and the image of the grating or light spot maintains the original shape because there is no target on th...

Abstract

A method for recognizing target includes irradiating the light beam from light source via raster or optical pattern onto the monitored plane, reflecting it to receiver, sending the received signals to processor, and fastly recognizing if there is a target on the monitored plane for providing useful control signal. Its advantages are high speed and high anti-interference performance.

Description

(1) Technical field [0001] The invention relates to a method for identifying targets, in particular to a method for identifying obstacles by using photoelectric and digital image processing techniques during the travel of civilian vehicles and ships. (2) Technical background [0002] The existing common target recognition technology for civilian vehicles and ships generally uses radar systems. When this system identifies small targets, such as targets below 0.25 square meters, it is easy to make mistakes in judgment, and the cost is as high as tens of thousands of yuan. There is also an ultrasonic identification system, which has low anti-interference performance and poor effect. Therefore, above-mentioned two kinds of systems fail to be widely used in civil vehicles and ships, especially on vehicles. And the lack of early warning devices, in the process of moving vehicles and ships, accidents are prone to occur, and there are potential safety hazards. (3) Contents of the...
