Space target characteristic identification device based on image sensing technology

Abstract

The invention belongs to the technical field of embedded information and relates to a space target characteristic identification or measurement device based on an image sensing technology. The device is characterized in that an image sensor is a high-frame or high-density complementary metal oxide semiconductor (CMOS) device; after the image sensor is driven, a digital image signal is output; the data quantity is large and can be hundreds of megabits to thousands of megabits at each second, so a high-speed data acquisition circuit, a storage circuit and a high-speed communication circuit are necessarily adopted; and when characteristic identification or measuring calculation is performed, a field programmable gate array (FPGA) circuit and a microcontroller circuit coordinate to calculate hierarchically. Therefore, image signal acquisition, image signal processing, image characteristic identification or measuring calculation must be performed simultaneously. A high-frame or high-density image acquisition and processing complex huge structure is concentrated into a minitype industrial camera, so the device is convenient to use, in particular, when multiple devices are used simultaneously, a huge number of image data does not need to be transmitted in a network and the burden of the network is reduced. The device has a small size, saves energy and is particularly suitable for being used outdoors.

Description

technical field [0001] The invention belongs to the field of embedded information technology, and relates to a network terminal image device, in particular to a space object feature recognition or measurement device based on high-frame or high-density image sensing technology. Function of the target geometry. High-frame images (up to 500 frames) involve fast-moving targets, and high-density images (up to 12 million real pixels) involve high resolution. Background technique [0002] At present, the implementation of image recognition technology is generally composed of three parts: industrial camera, acquisition card, and computer. The price is high, the system is complex and bulky, and it is not suitable for batch use and field use. This structure usually needs to transmit the image data to the computer first.

[0002] At present, the implementation of image recognition technology is generally composed of three parts: industrial camera, acquisition card, and computer. The price is high, the system is complex and bulky, and it is not suitable for batch use and field use.

This structure usually needs to transmit the image data to the computer first. When high-definition or high-frame requirements are required, due to the transmission of huge amounts of data and the limited bandwidth of the communication channel, it is not easy to meet the technical indicators of high data transmission rates.
