Vehicular obstacle detection device capable of indicating obstacle distance

Abstract

The invention relates to a vehicle obstruction testing device used for dropping a hint of obstruction distance. A plurality of store fields are divided in the memory of the device. The store fields respectively correspond to position coordinates that ultrasonic signals can reach. And then, the ultrasonic signals are analyzed by a CPU to calculate the position coordinate data of the obstruction. Status data that means whether the obstruction exits or not is filled into the store field. Afterwards, a corresponding section is divided by a video image superposition module in a video image captured by a video image capture according to the position coordinate represented by every store field. The corresponding section is matched with the position of an ultrasonic sensor and the status data of store field memory, so as to lead a display to show the image superposed by the video image of an ultrasonic transmission path and the video image captured by the video image capture.

Description

technical field [0001] The invention relates to a vehicle obstacle detection device, in particular to a vehicle obstacle detection device which can indicate the obstacle distance. Background technique [0002] Today, as technology is more and more developed, the reversing radar has almost become the basic equipment of the car. Generally, the reversing radar is installed with an ultrasonic sensor at the rear of the car. When the reversing file is entered, the ultrasonic sensor is activated to emit ultrasonic signals. When the ultrasonic signal encounters an obstacle, it will turn back and be received by the ultrasonic sensor, and then use the sound alarm installed in the car to prompt and convey the obstacle information to the driver, thereby assisting the driver to complete the parking process smoothly. [0003] At present, there is a better reversing radar device on the market, which further uses a camera to take pictures of the rear, and then presents the rear images on th...

Problems solved by technology

[0004] When the above-mentioned reversing radar device is used, it is still impossible to know the relative relationship between the rear of the car and the obstacle. Although the digital information representing the distance has been presented on the display, it is only a digital presentation for the driver and cannot be viewed from the screen. The image concept representing the distance from the obstacle can be obtained directly on the computer, so the digital concept must be converted into the actual distance concept again
