Device for improving vehicle-mounted binocular vision system performance and use method thereof

Abstract

The invention discloses a device for improving vehicle-mounted binocular vision system performance and use method thereof. The device is connected between a camera module and an ADAS host; the cameramodule comprises two camera units, the device comprises a data receiving module, a gray processing module, an exposure control module, a digital zoom module and a data sending module; the effective exposure control can be performed on the camera module without using an ISP chip, the redundancy and cost rising are avoided; and meanwhile, the digital zoom is performed on the data image according tothe vehicle speed before performing the data processing on the ADAS host, thereby effectively reducing the visual angle, amplifying an attention region, relieving the ADAS host computing burden, and improving the response speed; and the ADAS whole performance is further improved.

Description

technical field [0001] The present invention relates to the field of forward collision warning (Forward Collision Warning, hereinafter referred to as FCW) of advanced driver assistance systems (Advanced Driver Assistance Systems, hereinafter referred to as ADAS), and more specifically, relates to a method for detecting forward objects through a binocular camera. A system that realizes the FCW function through ranging perception. Background technique [0002] As one of the important functions of ADAS, FCW assists the driver to avoid or slow down high-speed, low-speed rear-end collisions and collisions with forward obstacles by identifying forward obstacles. In FCW, sensors such as radars and cameras are usually used to perceive obstacles in front to complete the early warning function. In the prior art, binocular vision system distance measurement is to use the left and right image pairs captured by two cameras at the same time to perform stereo matching, and calculate the d...

Problems solved by technology

[0005] Aiming at the disadvantages in the prior art of using ISP chips to push up the cost and the ADAS host’s computational burden being too heavy to limit the response speed, the technical problem to be solved by the present invention is to propose a device placed between the camera module and the ADAS host. The device can improve the performance of the vehicle-mounted binocular vision system, reduce system redundancy, and adjust the output image of the device according to the vehicle speed, so as to be more suitable for the calculation of the ADAS host, reduce the burden on the ADAS host, and improve the response speed
