Embodiment Construction

[0029] Regarding the technology, means and effects used in the present invention, a preferred embodiment is given and described in detail below with drawings, which are for illustration purposes only, and are not limited by this structure in the patent application.

[0030] refer to figure 1 , is a schematic diagram of the use of the distance measuring function of the present invention. The present invention includes a light source 10, a lens group 20 and a display 30 to measure the images of the first object A and the second object B to be measured and the distance from the vehicle. distance, where:

[0031] refer to Figure 2 to Figure 5 , the light source 10 is installed at the rear of the car, the light source 10 can project a light 11, the light 11 can be projected on the objects A and B at the rear of the car, and appear on the objects A and B A pattern 12, the pattern 12 is a regularly arranged mesh grid, and the light 11 is invisible light, so it will not affect the...

Abstract

A reverse image device with a ranging function is composed of a luminous source, a lens group and a display, wherein the luminous source is arranged at the tail of an automobile and can project a ray which can generate a pattern on an object to be measured; the lens group is arranged at the tail of the automobile and is internally provided with a lens, a photo-sensitive component and a circuit board, the lens collects images at the rear part of the automobile to be projected on the photo-sensitive component, and the circuit board calculates the off-car distance between the object to be measured and the tail of the automobile based on the pattern compactness read by the photo-sensitive component; and the display is arranged in the automobile for a driver to view and is electrically connected with the lens group so as to enable the display to display the off-car distance between the image of the object to be measured and the object to be measured. By pattern compactness projected by the luminous source, the off-car distance of the object to be measured is calculated so as to avoid the driver from judging the off-car distance of the object to be measured by mistake; and the ray is invisible light, thus having no influence on coming vehicles or pedestrians at the back.

Description

technical field [0001] The present invention mainly discloses a reversing image device with a distance measuring function, especially a reversing image device that uses light to project on an object to be measured to measure the distance from the vehicle. Background technique [0002] refer to Figure 9 to Figure 11 , is a schematic diagram and display screen of a conventional reversing image device, which has a lens 101 and a display 102, and there are a first object to be tested a and a second object to be tested b at the rear of the car, wherein the first object to be tested a and the second object to be tested The height and size of the two test objects b are about the same. When the lens 101 collects the first test object a and the second test object b respectively, on the screen of the display 102, the visual distance from the vehicle of the first test object a The visual distance from the vehicle is closer than that of the second object under test b, and visually matc...
