Abstract

An in-vehicle driving image map data establishment system is provided, and includes an image capture apparatus, a vehicle speed unit, and a control apparatus. The image capture apparatus continuously captures and outputs a plurality of outside-vehicle images. The vehicle speed unit continuously detects and outputs real-time vehicle speed information. The control apparatus is electrically connected to the image capture apparatus and the vehicle speed unit, the control apparatus continuously receives the real-time vehicle speed information, and the control apparatus selectively controls, when the real-time vehicle speed information is greater than a threshold, the image capture apparatus to capture the outside-vehicle images at a first frequency, or the control apparatus selectively controls, when the real-time vehicle speed information is less than the threshold, the image capture apparatus to capture the outside-vehicle images at a second frequency, in which the second frequency is less than the first frequency.

Claims

1. An in-vehicle driving image map data establishment system, comprising:

at least one image capture apparatus, continuously capturing and outputting a plurality of outside-vehicle images;

a vehicle speed unit, continuously detecting and outputting real-time vehicle speed information; and

a control apparatus, electrically connected to the image capture apparatus and the vehicle speed unit, wherein the control apparatus continuously receives the real-time vehicle speed information, and the control apparatus selectively controls, when the real-time vehicle speed information is greater than a threshold, the image capture apparatus to capture the outside-vehicle images at a first frequency, or the control apparatus selectively controls, when the real-time vehicle speed information is less than the threshold, the image capture apparatus to capture the outside-vehicle images at a second frequency, wherein the second frequency is less than the first frequency.

2. The in-vehicle driving image map data establishment system according to claim 1, further comprising an image upload apparatus, electrically connected to the control apparatus and the image capture apparatus, and receiving the outside-vehicle images, wherein the control apparatus further controls, when the real-time vehicle speed information is greater than the threshold, the image upload apparatus to wirelessly transmit the outside-vehicle images to the outside at a third frequency, or the control apparatus further controls, when the real-time vehicle speed information is less than the threshold, the image upload apparatus to wirelessly transmit the outside-vehicle images to the outside at a fourth frequency, wherein the fourth frequency is less than the third frequency.

3. The in-vehicle driving image map data establishment system according to claim 1, further comprising an image processing apparatus, electrically connected to the image capture apparatus, wherein the image processing apparatus receives the outside-vehicle images, and correspondingly outputs a plurality of processed images, and a data amount of each of the processed images is less than a data amount of each of the outside-vehicle images.

4. The in-vehicle driving image map data establishment system according to claim 3, wherein each of the processed images is combined from two adjacent outside-vehicle images.

5. The in-vehicle driving image map data establishment system according to claim 3, wherein each of the outside-vehicle images comprises a near-field image and a far-field image, and each of the processed images comprises only the near-field image.

6. The in-vehicle driving image map data establishment system according to claim 3, wherein resolution of each of the processed images is less than resolution of each of the outside-vehicle images.

7. The in-vehicle driving image map data establishment system according to claim 3, further comprising an image upload apparatus, electrically connected to the image processing apparatus, wherein the image upload apparatus wirelessly transmits the processed image to the outside.

8. The in-vehicle driving image map data establishment system according to claim 7, wherein the control apparatus is connected to the image upload apparatus, and the control apparatus controls, when the real-time vehicle speed information is greater than the threshold, the image upload apparatus to wirelessly transmit the outside-vehicle images to the outside at a third frequency, or the control apparatus further controls, when the real-time vehicle speed information is less than the threshold, the image upload apparatus to wirelessly transmit the outside-vehicle images to the outside at a fourth frequency, wherein the fourth frequency is less than the third frequency.

9. The in-vehicle driving image map data establishment system according to claim 1, further comprising an image identification apparatus, electrically connected to the image capture apparatus and the control apparatus, wherein the image identification apparatus receives each of the outside-vehicle images, and correspondingly outputs a quantity of the identified objects, and the control apparatus controls, when the quantity of the identified objects is greater than a preset value, the image capture apparatus to capture these outside-vehicle images at an adjusted frequency, wherein the adjusted frequency is greater than the first frequency and the second frequency.

10. The in-vehicle driving image map data establishment system according to claim 1, wherein there is a plurality of thresholds, and there are a plurality of first frequencies and a plurality of second frequencies.
