Abstract
An apparatus includes a capture device and a processor. The capture device may be configured to generate pixel data corresponding to an exterior view from a vehicle. The processor may be configured to perform operations on video frames generated from the pixel data to detect a moving object in the video frames, determine a predicted path of the moving object, determine a probability of the moving object colliding with the vehicle based on the predicted path, determine whether the vehicle is stationary and generate a control signal if the vehicle is stationary and the probability is greater than a pre-determined threshold. The control signal may be configured to enable a response to alert a person in control of the moving object.
Claims18
An apparatus comprising:
- a capture device configured to generate pixel data corresponding to an exterior view from a vehicle;
- and
- a processor configured to (i) process said pixel data arranged as video frames, (ii) perform computer vision operations on said video frames to detect a moving object in said video frames, (iii) determine a predicted path of said moving object, (iv) determine a probability of said moving object colliding with said vehicle based on said predicted path, (v) determine whether said vehicle is stationary, (vi) perform said computer vision operations on said video frames to measure distances to lines of a parking space occupied by said vehicle and (vii) generate a control signal if (a) said vehicle is stationary and (b) said probability is greater than a pre-determined threshold, wherein
- (i) said control signal is configured to enable an autonomous movement of said vehicle in order to move said vehicle to avoid said predicted path of said moving object,
- (ii) said predicted path is determined by tracking said moving object over time in a sequence of video frames,
- (iii) said autonomous movement comprises a low speed avoidance maneuver within said distances measured,
- (iv) said distances measured define a bounds of said parking space, and
- (v) said autonomous movement comprises moving said vehicle to avoid said predicted path of said moving object while staying within said bounds of said parking space.
