Automatic-configuring system for digital photogrammetric optical parameters

Abstract

The invention relates to an automatic-configuring system for digital photogrammetric optical parameters, which mainly comprises an ambient light sensor, a computer, a system controller, a light distribution floodlight and an image sensor, wherein the input ends of the ambient light sensor and the system controller which are arranged at a test area of the image sensor are connected with a data acquisition card of the computer through shielding signal wires, and two output ends of the system controller are respectively connected with the light distribution floodlight and the image sensor through signal wires. Light strong signals of the test area are directly sent to the computer through signal wires, the computer figures out the best light distribution parameters of the image sensor according to the light strong signals and sends a control instruction to the system controller, and the system controller controls the turning-on and off of the light distribution floodlight and regulates the light distribution parameters of the image sensor in real time according to the control instruction sent by the computer. The system can be used for effectively measuring high-speed moving objects and can ensure that the image effect measured by the image sensor is best.

Description

technical field [0001] The invention relates to an automatic configuration system of digital photogrammetry optical parameters for improving the photosensitive effect, in particular to an automatic configuration system of optical parameters for digital photogrammetry of high-speed moving objects outdoors. Background technique [0002] Because digital photogrammetry technology has many characteristics such as high test accuracy, fast test speed, good environmental adaptability, and convenient use, digital photogrammetry technology has been widely used in various fields of human production and life in today's society. [0003] The accuracy of digital photogrammetry is directly related to the sharpness of the image of the measured object. If the exposure is insufficient, the important details of the measured object will be blurred on the measured image, which will not only affect the accuracy of photogrammetry, but also cause serious problems. The measurement features cannot be...

Problems solved by technology

The disadvantage of this method is that it is only suitable for the measurement of stationary targets and moving targets with slow moving speeds, because the photosensitive sensor is used to measure the brightness of the image in the target area and configure (adjust) optical sensors such as the aperture of the image sensor and the exposure time accordingly. The parameter takes more than 1 second, which cannot meet the needs of the measurement of high-speed moving targets (such as high-speed vehicles)
