Abstract:
Methods and systems can augment 360 degree panoramic LIDAR results (e.g., from a spinning LIDAR system) with color obtained from color cameras. A color-pixel-lookup table can specify the correspondence between LIDAR pixels (depth/ranging pixels) and color pixels, which may be done at different viewing object distances. The operation of the color cameras can be triggered by the angular positions of the LIDAR system. For example, a color image of a particular camera can be captured when the LIDAR system is at a particular angular position, which can be predetermined based on properties of the cameras (e.g., shutter speed). Alternatively or in addition, a common internal clock can be used to assign timestamps to LIDAR and color pixels as they are captured. The corresponding color pixel(s), e.g., as determined using a color-pixel-lookup table, with the closest timestamp can be used for colorization.

Claim (Index 1):
A panoramic color light detection and ranging (LIDAR) system comprising:\n a stationary base; a LIDAR system rotationally coupled to the stationary base and configured to perform a plurality of ranging measurements by transmitting light and detecting reflected light to acquire a LIDAR image including a plurality of LIDAR pixels distributed around an angular field of view; a plurality of color cameras fixedly coupled to the stationary base and disposed circumferentially around the LIDAR system, each camera having a respective camera field of view that is a portion of the angular field of view, the plurality of color cameras configured to acquire a plurality of color images comprising a plurality of color pixels; a memory storing a color-pixel lookup table that defines mappings between the plurality of LIDAR pixels and the plurality of color pixels; a controller operatively coupled to the memory and configured to:\n trigger an image capture of each of the plurality of color images based on a determined angular position of the LIDAR system relative to a respective camera field of view so as synchronize capturing of a portion of the LIDAR pixels with capturing of color pixels of a respective camera of the plurality of color cameras; and \n associate at least one of the plurality of color pixels with a corresponding LIDAR pixel of the plurality of LIDAR pixels using the color-pixel lookup table stored in the memory, thereby generating a colorized LIDAR pixel.
